Editor’s note: Coastal Review regularly features the work of North Carolina historian David Cecelski, who writes about the history, culture and politics of the North Carolina coast. More of his work can be found on his website.

I first listened to a special group of interviews with African American community elders in Pamlico County almost 20 years ago, but I have never forgotten them. They helped me to see history as more than dates and wars, the rise and fall of the powerful, and the stuff of headlines.

They helped me to understand that history is all those things, but it is also the paths of our souls and the life of the spirit.

The oral history project was called “Preserving the African American Experience in Pamlico County, North Carolina.”

The project was led by Ms. Linda Simmons-Henry, a scholar, archivist and public historian whom I have known and admired for many years.

Ms. Simmons-Henry was uniquely well prepared to lead the project. At that time, she was the director of special collections and the senior archivist at Saint Augustine’s College in Raleigh.

She is currently the dean of the library and archives at Texas College, a historically Black colleges and universities in Tyler, Texas.

She is also a native of New Bern and has always remained deeply attached to the African American community there and in Pamlico County, just to the east of New Bern.

Over the spring and summer of 2007, Ms. Simmons-Henry and a talented team of local volunteers conducted oral history interviews with 20 of Pamlico County’s African American elders.

I found the interviews to be a rare treasure. Taken together, they are a compelling and intimate portrait of African American life in Pamlico County over most of the 20th century.

The whole tenor of the interviews is special. When you listen to them, you can tell that the project’s volunteers and the elders were people who knew and cared for one another.

In the voices of the project’s volunteers, I heard respect and reverence for the elders whom they were interviewing. I also heard a yearning to learn from their wisdom and experience.

In the voices of the elders, I heard a special kind of care. They talk about history, but they also sound like wise grandparents gently sharing love and guidance with those of a younger generation whom they know will need all the help they can get in this fragile, broken world of ours.

* * *

I first listened to the interviews back in 2007. The project’s volunteers had organized a banquet to celebrate and honor the community elders who had so graciously shared their stories with them.

I had been invited to say a few words at that banquet. To help me to prepare for the occasion, Ms. Simmons-Henry made a copy of the interviews for me.

At that time, the project’s volunteers had not yet transcribed the audio tapes, so I could not read transcripts of them. In a way, it was nicer: it meant that I had to listen to them, which I did, and it was a delight.

It made me feel as if I was sitting down with the elders and listening to their stories along with the project’s volunteers.

The interviews and transcripts are now available both at the New Bern-Craven County Public Library in New Bern and in the Southern Oral History Program’s collection at the Southern Historical Collection at University of North Carolina Chapel Hill.

* * *

The project’s oldest interviewee was a woman named Annie Rachel Squires. She was born in a little community called Maribel, on the Bay River, in 1908. At the time of her interview, she was 99 years old.

Ms. Squires and the other community elders shared stories about many different parts of Pamlico County’s history.

They talked about their teachers and schools. They spoke of childhood joys. They remembered long, brutally hard days of digging in potato fields and shucking oysters in the local canneries.

“All I know about my life was work, work, work,” I remember one woman saying, I believe in Vandemere, a small village in Pamlico County.

The community elders also recounted tales of the local struggle for voting rights and racial justice in Pamlico County.

Some remembered the landmark school desegregation lawsuit that black citizens in the coastal town of Oriental filed in 1951. Two or three recalled incidents involving the Ku Klux Klan.

Others told stories about serving in the Second World War and the Vietnam War. Yet others remembered the Great Depression.

My curiosity encompassed all of those historical subjects, but they are not what I remember most about the interviews.

What struck me most deeply about the elders’ words when I first listened to them back in 2007, and what I still find most unforgettable about them now, is how much they are a history of faith and the spirit.

* * *

For instance, I will never forget the project’s interview with the Rev. Kenneth M. Bell Sr., who at that time was still the minister at the Green Hill Missionary Baptist Church in Bayboro.

He was the only church pastor whom the project’s volunteers interviewed, but when it came to matters of the spirit, his words were very similar to most of the other elderly men and women that were interviewed.

Like Rev. Bell, they spoke of their faith and their struggles to know and understand God more fully.

They shared stories of Sunday schools and Bible study groups. They described a hunger to understand more fully what Scripture had to teach them about our purpose here on Earth, the nature of our existence, and what we are called to do for one another.

Rev. Bell was interviewed by Ms. Sandra Mae Hawkins, one of the project’s most devoted volunteers. At one point in the interview, she asked Rev. Bell what he considered the most important event in his life.

He did not hesitate for even a second.

He said it was the day in his boyhood that Mrs. N.F. Harper sang “Pass Me Not O Gentle Savior” at Green Hill Missionary Baptist Church and he accepted Jesus Christ as his Lord and savior.

* * *

When Rev. Bell spoke of Mrs. Harper singing “Pass Me Not O Gentle Savior,” he was remembering a worship service 60 or 70 years earlier.

Born in Bayboro in 1941, he was the youngest of 12 children.

When Sandra Made Hawkins talked with him, he explained that he had grown up in hard times. However, he did not linger on his family’s hardships or the things they did without.

Instead, he talked about his father, who was a farmer and a devout member of the local African Methodist Episcopal Zion Church.

His father was not the pastor of the church, but he had been a missionary. Rev. Bell explained that when his father was not in his fields, he strove to live the Bible’s teachings.

He visited the sick, lonely, and down and out. He cut firewood for elderly neighbors. After hog killings, he shared the meat with those who had none.

In the interview, Rev. Bell recalled that his father’s face had been disfigured in a hunting accident when he was a boy.

When I heard that part of his life story, I wondered if his father’s malformity had helped to teach him, and maybe his son too, to look at people’s souls, not on that which is only skin deep.

Rev. Bell remembered that people in Pamlico County often referred to his father as a prophet. He said that his father understood how to listen for God’s word, and again and again, God spoke to him. God made him promises, and those promises, Rev. Bell said, came true.

He was not describing the world that we watch on TV or read about in the New York Times: he was describing a world where miracles happened.

 “He never talked much to us except about the Bible,” Rev. Bell recalled.

He spoke with great admiration and appreciation for his father. On the other hand, listening to his interview, I also got the feeling that he felt as if his father may have left some important things unsaid.

* * *

I was also taken with the project’s interview with a gentleman named Charlie Styron. Mr. Styron was born in Oriental in 1933.

I wish I had known him. He spoke with a beautiful voice, full of kindness.

In reflecting on his life, Mr. Styron described how he had always worked with his hands. Listening to him talk about his life, I got the impression that there was not much that he could not do with those hands.

For many years, he had worked at a sawmill and a veneer plant. But at different times, he explained, he had made his living as a heavy equipment operator, a bricklayer, a carpenter, and an electrician.

After he retired, he said, he found his greatest joy in playing with his grandchildren. He kept active, too. At the time of the interview, he was still operating a lawn mower repair business out of his home.

Passersby often saw him singing hymns and praying while he worked on the lawnmowers.

Sandra Mae Hawkins was also the project interviewer who spoke with Mr. Styron.

When she asked him, “What have been some important events of your life?” he, like Rev. Bell, did not hesitate even for a moment: “Well, to be born from above, that was the most important event,” he told her.

* * *

The project’s interview with a woman named Eula Felton Monk also stood out to me. Ms. Monk had grown up in Mesic, a rural, predominantly African American community on the Bay River.

I had a good friend there when I was young, Ed Credle, who was Mesic’s first mayor. Listening to Ms. Monk’s stories gave me a special joy because they brought back memories of Ed and his neighbors whom I got to know in Mesic back in those days, good people, all.

When Ms. Monk was a girl, she recounted, her father had been the captain of a shrimp trawler. He worked on the Bay River and out in Pamlico Sound, but he also followed the shrimp as far south as Key West.

At the time of her interview, Mrs. Monk had been a teacher for 43 years. She had retired from teaching full-time, but she was still working part time as a substitute teacher in the local public schools.

When asked about her childhood, she recalled long days of working in the fields: chopping cotton, digging potatoes, picking tobacco.

Her family worked on local farms, but also traveled to fields as far away as Merritt, Arapahoe and Aurora.

She spoke of her schoolteachers with great reverence. She had endless admiration for how they did so much, and cared so much for their students, back in those days of Jim Crow when Pamlico County’s schools were segregated by race and so little was given to the African American schools.

Mrs. Monk said that she would never forget the great debt that she owed those teachers.

When the interviewer asked her if she was religious, she, too, was matter of fact:

“I believe in God and I believe in being a doer of His word…, (and I) try very hard to do those things daily that He says that I should do in His world.”

The interviewer then asked a question with a kind of directness with respect to faith and religion that I do not often see in oral history projects.

She asked if Mrs. Monk believed in Jesus Christ.

Mrs. Monk was not caught off guard by the question in the least, and her reply was direct:

 “Oh, yes I do, as my Lord and my Savior. He is my Savior. Yes.”

When the interviewer asked her how she put her faith into action in her daily life — another question I do not often hear in oral history interviews — Mrs. Monk turned to Scripture.

“Second Timothy 2:15 says to study to show thyself approved of God, not to be ashamed, rightly dividing the word of truth. I study the word of God, and then I pray.”

She also said:

“And the Bible says we should visit the sick…, the Bible says that we should reach out to those who are less fortunate than we are… and to love thy neighbor as thyself.”

She said that she strove to do all those things, though of course she acknowledged that she was far from perfect.

Then she said:

“I love God with all my heart and all my mind, and all my soul. And I would like to say, the greatest point in my life, the most important event in my life, is when I accepted Jesus as my Lord and Savior, when I became saved.”

* * *

As I listened to their voices, I found a comforting sense of familiarity in the way that the lives of the Pamlico County elders were entwined so tightly and so seamlessly with their faith and their churches.

I grew up just across the river from Pamlico County, and I found that their voices reminded me again and again of home and the lives of my family and the people around whom I was raised.

* * *

There was a kind of cadence to the stories of their lives, like a gentle heartbeat, held steady by their knowledge of themselves as spiritual beings and kept in time by daily prayer, Bible study, worship services, Sunday school, church suppers, choir practices, baptism, weddings and funerals.

So many little things in these interviews caught my attention, and they did so in a way that, even all these years later, they remained fixed in my memory.

Listening to the interview with Annie Squires, the 99-year-old woman I mentioned earlier, I could feel how her heart filled with joy when she played the piano at her church in Maribel.

She told the young woman who interviewed her that she had been the church’s pianist for more than half a century.

Likewise, in my mind’s eye, I could see Roosevelt Stokes Jr., another of the interviewees, as he made his weekly rounds among the frail and sick in Grantsboro’s nursing home.

He had never been a pastor or a missionary at a church, but he had his own ministry visiting those people who lived in the nursing home.

On the days of his nursing home visits, Mr. Stokes would stop and read the Bible to any of the patients who desired him to do so.

He would hold their hand, and often they would pray together. Sometimes one of the nurses would join them.

His words brought back memories for me, and maybe helped me appreciate what it was like for Mr. Stokes to read the Bible by those bedsides, and how much it might have meant to those who lay there. Because, now and then, I have been called on to read the Bible at a bedside, too.

* * *

I know these are just little moments, but even some of the passing comments in the interviews made a deep impression on me.

For instance, another of the interviewees, Emma Bell, recalled how, when she was a small child, her mother began every day by giving a Bible verse to her and to each of her brothers and sisters.

They would read the Bible passage at breakfast.

I could see them: a mother and her children, early in the mornings of what I am sure were busy days, taking a few minutes to recite Bible verses before going out into this stormy world of ours.

I also loved a little something that one of the other interviewees, Sabia Ruth Gibbs, said.

Ms. Gibbs grew up in Maribel. Way up in her 90s, she was one of the oldest people who shared her life story with the project’s volunteers.

All the same, when she was asked to pause for a moment and think about the long span of her life, one of the first things she did was reach far back in time, as if to another world, and describe the joy of singing in the choir at St. Galilee Missionary Baptist Church when she was a girl.

She remembered it like it was yesterday.

It was a memory, in her telling of it, that seemed to be made of pure light.

* * *

I doubt that I am much different from anyone else. When I am driving through the countryside, as I did last night, on my way to my family’s homeplace on state Highway 101, I go by all the homes and see the lights on and I wonder how the people that live there are doing, and do they feel loved, and, if they pray, what they pray for at night before they fall asleep.

I wonder about their prayers, and all that goes unsaid in life, and the whispered words we have between us and our maker.

At those times, I think about the quiet joys for which we show gratitude at that late night hour. I think too of the fears that go unsaid everywhere else, the dreams that we keep to ourselves, the hungers that can’t be put into words.

The interviews in “Preserving the African American Experience in Pamlico County, North Carolina” are an invaluable historical record of life on the North Carolina coast throughout the 20th century.

The more times that passes, the more special they will seem, the more important they will be.

I cherish them for that reason but also because they help me to remember that our path through life, our history, is partly what can be seen and heard and touched, and partly what cannot.

A team has scheduled two discussions for later this month to hear from Ocracoke residents their thoughts on the challenges associated with changes to the physical environment the island is likely to experience.

University of North Carolina Chapel Hill, North Carolina State University, Duke University and East Carolina University researchers have already completed a multiyear research project that simulates how the physical landscape such as beaches, shoreline, dunes and marshes of Ocracoke Island may change in the future because of road management decisions.

The team now is looking to hear from residents their perspective on meeting these challenges, particularly to transportation and accessing the island.

Sessions are scheduled for 1-3 p.m. Friday, Jan. 30, and 10 a.m.-noon Saturday, Jan. 31, at the Ocracoke Community Center. Reserve a spot to join the discussion. Participants must be an adult residing in Ocracoke.

“We’re conducting community deliberative dialogues to better understand your unique perspective about the challenges Ocracoke faces due to increasing environmental hazards,” researchers said. The two “events are a part of a research study to gain a better understanding of how communities demonstrate scientific literacy, within the context of coastal resilience issues and solutions.”

A deliberative dialogue is a structured discussion, moderated to help foster open conversations and provide an opportunity to share and hear different perspectives.

K.C. Busch, who can be reached at kbusch@ncsu.edu, is leading the study titled, “Redefining Scientific Literacy At The Community Level.”

Student researchers will present their findings on Nags Head Woods during the next installment of the “Science on the Sound” lecture series presented by the Coastal Studies Institute on the East Carolina University Outer Banks Campus.

The lecture, “Patterns of protection: Natural and Social Values of the Nags Head Woods Maritime Forest,” is set for 3 p.m. Thursday, Dec. 11, at the Coastal Studies Institute, 850 N.C. Highway 345, Wanchese.

The program is free and the public is encouraged to attend. The program will also be livestreamed on YouTube.

The monthly, in-person, lecture series at the Coastal Studies Institute brings perspectives from all over the state and highlights coastal topics in northeastern North Carolina.

During this month’s program, students of the Outer Banks Field Site will present the findings of their capstone research project.

The University of North Carolina Chapel Hill Institute for the Environment’s Outer Banks Field Site is a semester-long, interdisciplinary residential learning experience for undergraduate students hosted by the Coastal Studies Institute. Each fall since 2001, these students have spent the semester taking classes, engaging in internships with local organizations, and completing a capstone research project as a group.

This year’s research examines the maritime forest within the Nags Head Woods Preserve. The students interviewed stakeholders about the values that they ascribe to the woods and collected data about the salt spray, vegetation, and wildlife within the woods. The program will last about 90 minutes, including presentation, questions and discussion.

This report was updated Nov. 25 to include information on arrangements.

Former North Carolina Supreme Court Justice Willis Padgett Whichard, one of four individuals widely credited for securing passage of the state’s Coastal Area Management Act, died Monday in Chapel Hill, sources close to the family confirmed this week.

A 1962 graduate of the University of North Carolina, Whichard left Chapel Hill three years later with a law degree. He served two terms as member of North Carolina House of Representatives from 1970 until 1974, when he was first elected to the state Senate. Whichard served three Senate terms and, in 1980, Gov. Jim Hunt appointed Whichard to the North Carolina Court of Appeals. In 1986 he became an associate justice of the North Carolina Supreme Court, serving until he retired in 1998.

“While a sitting justice, he somehow found time to earn his doctorate of systematic jurisprudence from the University of Virginia,” according to a Carolina Alumni article about his General Alumni Association Distinguished Service Medal citation. “That is the top degree possible for a legal scholar—one that very few lawyers and judges possess.” The citations are read aloud during the annual alumni luncheon and then presented to recipients.

Author, musician and UNC professor Bland Simpson called Whichard “an almost legendary man of many superlatives, and one of the most important of his legion of accomplishments was helping move the Coastal Area Management Act through the legislature in 1973-74.”

In an email Monday, Simpson told Coastal Review that he and Whichard spoke of the fight for CAMA on numerous occasions, “and he always said there were four individuals key to making this all-important bill into law.” Those individuals were then-Gov. James Holshouser, Milton Heath, who was a professor at UNC’s Institute of Government and wrote the bill, Sen. Bill Staton of Lee County, and Rep. Whichard from Durham County, who Simpson said carried the bill through the House.

“When CAMA passed the legislature, it was widely seen as the most comprehensive, progressive, protective coastal legislation become law in the nation,” Simpson said. “Whichard was a giant, a visionary, and the last surviving member of the quartet that gave us CAMA.”

Author, photographer, conservationist and attorney Tom Earnhardt told Coastal Review in an email Tuesday that in summer 1970, he worked a student clerkship with the Powe, Porter and Alphin law firm in Durham.

“E.K. Powe and others in the firm were well known North Carolina lawyers,” Earnhardt said, adding that the lawyer who taught him the most Whichard, then the youngest lawyer with the firm. “Bill always made the time to read and give a quick edit to anything I prepared. Always a mentor, he was exactly the same Bill Whichard I’ve known for the last 55 years — humble, patient, compassionate, and brilliant.”

Earnhardt said that, years later, he worked with Gov. James Holshouser to secure legislative funding for Cape Lookout National Seashore. He said that Whichard, then a House member, quickly took up the cause.

“After I had gotten several emphatic rejections from more senior officials, Bill assured me he’d help find the money. I still remember his political assessment of the North Carolina General Assembly at the time: ‘You’ve got to remember that in the General Assembly there will always be Members who will vote against the Creation to preserve the pre-existing darkness!’”

Earnhardt said that in each of Whichard’s roles, he “was always the brightest light in the room. No one has served North Carolina better.”

That sentiment was shared in the Campbell Law Review’s spring 2006 edition, which noted that, Whichard had served in both the legislative and judicial branches of government, “and in so doing, he has the distinction of being the only person to serve in both the House of Representatives and the Senate in the North Carolina General Assembly and on both of our appellate courts, the Court of Appeals and the Supreme Court of North Carolina. In each of these significant areas of service, Willis Whichard has established records of lasting import.”

Born in 1940 in Durham, Whichard was an adjunct law professor at UNC from 1986 until 1999. He was dean and law professor at Campbell University from 1999 until his retirement in 2006.

From 2006 to 2013, Whichard practiced as a partner with the Moore & Van Allen law firm’s Research Triangle Park office.

In 2013, Whichard joined the Chapel Hill law firm, Tillman, Whichard, and Cagle.

In 2019, Whichard and Raleigh attorney Scott Miskimon were presented Friend of the Court awards for their service to the Judicial Branch and work on the Supreme Court’s bicentennial exhibit at the North Carolina Museum of History. Whichard led the effort to create the North Carolina Supreme Court exhibit, “Law and Justice: The Supreme Court of North Carolina, 1819-2019.”

The News & Observer reported Nov. 24 that Clements Funeral & Cremation Services of Durham is handling the arrangements, and a public memorial service is planned for January.

Those slabs of meat labeled “shark” on display in grocery stores and seafood markets might be from a critically endangered species and contain significant levels of mercury, according to a new study.

The University of North Carolina Chapel Hill paper, “Sale of critically endangered sharks in the United States” was published Tuesday in Frontiers in Marine Science journal. The study was funded by the university and the National Science Foundation.

Students in the university’s undergraduate-level seafood forensic course analyzed the DNA of 29 shark meat samples collected from 19 filets purchased in grocery stores, seafood markets and Asian specialty markets, mostly in North Carolina, and from 10 products called “jerky” that was ordered online.

Out of the samples, 27 “were ambiguously labeled as shark or mako shark but not as a specific species.” Of the two samples that were labeled, one was shortfin shark mislabeled as blacktip shark, and the other was correctly labeled.

The students identified 11 different species, three of which the Union for Conservation of Nature has designated as critically endangered: great hammerhead, scalloped hammerhead and tope.

“Previous studies have found that the first two species contain very high levels of mercury, illustrating the implications of seafood mislabeling for human health. The availability of shark meat in U.S. grocery stores is surprising given the dramatic decline of shark populations globally,” the authors wrote. “Moreover, the fact that nearly all shark meat is labeled ambiguously or incorrectly amplifies the problem. Accurate, verified product labels for shark meat would benefit consumers and shark conservation efforts, and should be a priority for the seafood industry.”

Savannah Ryburn, the lead author of the study, is a marine ecologist who recently earned her doctorate from UNC Chapel Hill. She and distinguished professor John Bruno are co-instructors for the class.

Ryburn told Coastal Review Tuesday that the main goal of the study was to figure out what species are being sold and if there’s any cause for concern, to which, “we would say ‘yes.’”

Just in the 29 samples analyzed, three were the meat of critically endangered species that are extremely high in mercury, which can be very dangerous for human consumption, Ryburn highlighted.

Finding the highly endangered shark species among the samples is a big conservation concern, “but even more perversely,” Bruno explained, these are long-lived, high-trophic level species with high mercury concentrations.

“Nobody should be eating hammerhead sharks,” Bruno said, because they’re loaded with mercury and the consumer has no idea, since the meat is sold as shark.

“We don’t know if it’s a spiny dogfish that’s low in the food chain, not very long lived, not very big, probably not super concerning in terms of tissue content, but there’s just no way to know,” Bruno added.

With this ambiguous labeling, Ryburn continued, sellers are taking away the consumer’s choice. “It’s very concerning when it comes to the general labeling,” particularly considering their findings are from such a small sample size. “It just raises more concerns for the actual shark meat market in the United States.”

Bruno explained that the shark populations are being decimated by fishing, and mostly for its fin. There are regulations in place that require the fisher to land the entire shark, not just cut off the fin, which is one reason the meat is being sold in stores.

Bruno explained that the fin is shipped to Asia, where it is in demand, and then the rest of the meat goes into either the pet food supply or the human food supply, but it’s not lucrative. The average price in the Raleigh area was around $5 a pound.

The United States Food and Drug Administration only requires sellers to have the meat labeled as shark, Ryburn continued.

The results of the study led the authors to emphasize “that sellers need to be required to label their product to the species name, rather than just shark, so that it can be more regulated and consumers have more of a choice,” she said. “In Europe, their regulations are a bit more specific when it comes to labeling sharks to the species level, so we definitely recommend following suit with that European regulation.”

Seafood Forensics

Bruno is a marine ecologist who, about a decade ago, designed the Seafood Forensics class for students to do the actual research testing and certifying seafood.

“We purchase seafood in grocery stores and restaurants, and we sequence it to identify what it really is, and we quantify mislabeling,” Bruno said. “We teach the undergraduate students about seafood mislabeling,” and use DNA barcoding to figure out what stores are actually selling.

Students are taught basic lab skills such as how to extract and sequence DNA, how to read the sequences and compare them to online databases, or DNA barcoding. Previous classes have studied red snapper and shrimp, for example.

Ryburn explained that the students design the research project they work on throughout the semester.

The idea to study shark meat evolved from a student telling the class that she noticed a grocery store was selling meat under the generic label of “shark,” though there’s hundreds of species of sharks, and they vary, she said.

The students collected the samples, most of which were labeled “shark,” and then began going through the process to identify the species.

About sharks

Ryburn, who studied sharks for her doctorate, said the animal is vital to the overall function and health of the marine ecosystem but “they’re currently being fished at extremely high rates throughout the whole world.”

Many of the species are long lived and, as a result, the populations don’t replenish quickly. If a large number is removed by fishing, it is hard for the population to recover at a sustainable rate.

She called sharks the “cleanup crew” for marine ecosystems, because they prey on injured or sick animals, making the populations of other species stronger.

If there are no sharks to help manage the population of other species, this will cause a cascading effect on the overall health within the ecosystem.

As for the threats to human health, shark meat is similar to tuna, in that there’s a very high level of mercury in its tissue, and that is due to something called bioaccumulation, which is the buildup of chemicals in an organism over time.

“Predators that are higher up in the food chain tend to accumulate more mercury in their tissue from the prey that they’re eating, because everything has mercury in its tissue,” Ryburn said. But with larger predators that live longer and eat bigger prey, the animal tends to accumulate more mercury, and that mercury never leaves the tissue.

Some shark species even eat tuna, like the mako shark, and they’re accumulating all of that mercury when they eat.

“If we go and eat something that’s super high in mercury, we’re also absorbing that mercury into our bodies, and mercury can cause major health issues and even cause people to die,” she said.

Plants on land are increasingly absorbing more carbon, while Earth’s oceans are taking in and storing less, according to a study released earlier this month.

The study published Aug. 1 in Nature Climate Change found a strong upward trend of global photosynthesis on land between 2003 and 2021.

That trend, however, is partially offset by a decline in photosynthesis occurring in oceans.

“At the global scale, if we put land and ocean together, it shows an enhanced photosynthesis, so that means, currently, our nature ecosystem is still showing an ability to absorb more carbon dioxide in the atmosphere,” said Yulong Zhang, a research scientist at Duke University’s Nicholas School of the Environment and primary author of the study. “Overall, this is encouraging news.”

That’s because, as the climate is warming, the system of plants, animals and microorganisms that referred to as the land ecosystem, still functions as a potential carbon sink to offset the carbon dioxide in the atmosphere, he said.

Plants on land and algae in oceans absorb carbon dioxide through photosynthesis, a crucial process that uses sunlight to create the base of the food chain.

But, it should be noted, Zhang said, that photosynthesis is a driver of carbon cycles because the ecosystem, like humans, can breathe out CO2.

Scientists have largely studied the net primary production, or the rate at which plants and phytoplankton store energy and make it available to animals, by focusing their research on either the land or sea.

Zhang primarily focused his research on the land until this study, one that treats both the land and ocean as two components of one global system and how those parts, together, are responding to climate warming through photosynthesis.

To conduct their study, the team of researchers used sets of data collected from satellites and large-scale climate information to create models to try and simulate various environmental factors, such as air and water-surface temperature, light and precipitation.

Scientists then compared year-to-year fluctuations in photosynthesis with the long-term trends on land and, separately, in oceans. The research team included scientists with the University of Iowa, Oak Ridge National Laboratory in Tennessee, University of New Hampshire, University of North Carolina Chapel Hill, and U.S. Forest Service.

“We found that, globally, the photosynthesis on land showing a strong increasing trend in the past 18 years from 2003 to 2021,” Zhang said. “But, by contrast, the ocean just shows a weak, declining trend.”

The rate at which plants on land store energy and make it available to animals during that 18-year span increased 0.2 billion metric tons of carbon per year, except in the tropics of South America.

During that same time, marine net primary production declined by about 0.1 billion metric tons of carbon per year, with strong declines occurring largely in tropical and subtropical seas, especially in the Pacific Ocean.

The trends show that during those 18 years global net primary production increased at an overall rate of 0.1 billion metric tons of carbon per year.

The changing trend of the land and the ocean are not uniform at the regional scale.

In tropical seas, scientists have found a large-scale decline in photosynthesis.

That’s a worrying pattern, Zhang said, because that decline equates to a decrease in energy that is provided to fish.

“So, the fishery in the tropical ocean may show a decline and it may particularly have influence on the local fisheries and also the economics for the tropical countries,” he said.

What remains unanswered is the question of what happens if this trend continues. Will the decline our oceans’ ability to absorb carbon continue and, if so, how long can the land ecosystem potentially make up for the declines?

To get answers, that will require “us to do long-term, coordinated monitoring of both land and ocean ecosystems as integrated components of our Earth,” Zhang said.

Coastal communities are inundated more often than previously believed, and floodwaters take longer to recede in rural areas than in urban areas, according to a new study.

The study, published Monday in the journal Communications Earth & Environment, also found that the way government agencies gather data used to predict floods fails to truly estimate how frequently water may get pushed over land.

“To capture the burden on coastal communities and to capture what people are really seeing on the ground, it’s so important to measure flooding on land,” said Dr. Miyuki Hino, a co-author of the study and assistant professor of city and regional planning at the University of North Carolina Chapel Hill.

What people living in Beaufort, Carolina Beach and Sea Level, an unincorporated area of Carteret County, told researchers they are seeing is that it floods “all the time,” said corresponding author Dr. Katherine Anarde, an assistant professor of coastal engineering at North Carolina State University.

“People know where it floods and a lot of people can put numbers to how frequently it floods, but as scientists, we just had no idea what ‘all the time’ meant,” she said.

To find that answer, researchers installed a network of in-house, custom-designed water level sensors in storm drains in Beaufort and Carolina Beach. Sensors were installed next to ditches cut along roads in Sea Level, a rural community about 28 miles northeast of Beaufort.

Each sensor measures when water rises and spills onto a nearby road.

The frequency at which that occurred during the course of the one-year study stunned researchers.

From May 2023 through April 2024, Beaufort experienced 26 days of flooding. Carolina Beach flooded 65 days.

And, “all the time” in Sea Level equated to 128 days of flooding. That’s one-third of the year, or once every three days.

“That was really shocking for me and I think for Miyuki too, just the sheer magnitude of flood days,” Anarde said.

It’s a reality in low-lying coastal areas where flooding is being driven more often by a combination of ingredients rather than large storm events.

The major ingredient, Hino said, is sea level rise. Rising seas strain storm drain systems and infrastructure designed decades ago when the ocean was much lower than it is today.

“And so while that highest tide 50 years ago, 100 years ago, might not have been high enough to get onto the road, now it is,” Hino said.

Sea level rise is exacerbating normal variations in water levels from tides and wind, which play a huge role in flood frequency.

If, for example, it rains on a day when a community’s storm drains are inundated with water from the tide, the rain that would normally drain into that system is pushed out across nearby roads.

But Mother Nature is not solely to blame.

Coastal areas have seen a population boom that has all but erased any semblance of what were once small fishing villages.

“Development definitely plays a role,” Anarde said. “Water has to have somewhere to go, and if the landscape is covered in impervious surfaces — roadways, buildings – then water is just going to sit on top of the road and on top of those impervious surfaces and create deeper, longer floods.”

Even in rural, low-lying areas that have fewer buildings and roads, water is not being absorbed into the ground at the rate it once was because sea level rise is elevating the groundwater table in the coastal plain.

One of the big motivations for installing the water level land sensors was to study how the different ingredients combine to cause flooding and, if you measure flooding from all of those sources, how the information gathered from those sensors compares to that taken from tide gauges.

Forecasters have widely relied on tide gauges to predict flood occurrences. The problem is, that is not what tide gauges are meant to do. And, there are many areas of the coast that are not close to a tide gauge, which are maintained by the National Oceanic and Atmospheric Administration.

“They do a great job at what they’re supposed to be doing, which is measuring water levels in oceans and bays,” Hino said. “But we knew that they’re not designed to measure flooding and that some of the other forces that influence flooding, like rain and local infrastructure, weren’t being captured there and so we wanted to know how accurate those tide gauge-based indicators are and how well they match up against what people living there are experiencing day to day and year to year.”

Over the course of the past five years, 11 land sensors have been installed in coastal areas of the state.

The information these sensors provide can help guide a community’s plan for a future expected to be only further impacted by sea level rise.

“We get asked a lot about how to fix this problem of more recurrent, chronic flooding in coastal areas,” Hino said. “There are solutions to the problem. They’re going to be different from place to place and many of them are going to involve difficult choices and so having more input from the affect people into what those choices are is really important.”

Jeremy Hardison, Carolina Beach’s director of Community Development, said in an interview last month that the study has “definitely” been a benefit to the town.

“We’ve kind of monitored how much water was in the street before, but not in the storm drains where the water is actually coming up during high tide events,” he said. “I don’t know that we would have come up with flooding sensors within our storm drains to monitor how much water is in our drains. We want to continue planning and we want to do some implementation and try to see what we can do to mitigate the problem so we’re working in that direction.”

​As the hours passed, day turning into night, prospects looked bleak for a research vessel carrying scientists and students hoping to get past the mouth of the Cape Fear River to deeper waters offshore.

The R/V Cape Hatteras had essentially been stuck at the mouth of the river for about 24 hours after leaving the morning of Feb. 10 from its mooring at Cape Fear Community College in downtown Wilmington, thanks to an abrupt change in the weather.

“I won’t lie, I did not think we would make it offshore, which feels like a waste with this large vessel to just be stuck at a spot we could sample fairly easily on smaller boats,” said Dr. Bradley Tolar, an assistant professor with the University of North Carolina Wilmington.

February tends to be a month when the weather serves up less-than-ideal working conditions offshore.

Cold temperatures, whipping winds and rain proved that to be the case during the first several hours of the maiden trip of the TEAL-SHIPS project, a groundbreaking expedition to study shore-to-sea habitats.

TEAL-SHIPS, an acronym for this mouthful: Transect Expedition to Assess Land-to-Sea Habitats via Interdisciplinary Process Studies, will allow researchers the opportunity to get an understanding of the biological, chemical and physical changes in habitats from the mouth of the Cape Fear River to the Gulf Stream’s warm waters.

This particular area of North Carolina’s coast has largely remained understudied since the 1990s. And those previous studies of the area between the 1970s and 1990s focused primarily on nearshore ecosystems.

Now, through a series of cruises (no, not the kind where mai tais are served on the pool deck), researchers of different coastal marine science disciplines hope to build a baseline in understanding how changes in the Gulf Stream flow affect the ocean’s food chain and critical habitats between the coastline and Atlantic continental shelf.

Tolar is spearheading the venture, one that was able to come to fruition through a $1.5 million General Assembly-funded grant through the University of North Carolina System Research Opportunities Initiative, a program that focuses on several research areas including marine and coastal science.

TEALS-SHIPS includes principal investigators from UNCW, the UNC Chapel Hill, North Carolina State University and East Carolina University.

Over the course of the next two years, researchers and some of their students will embark on an expedition about every three months, setting course to a series of stations mapped from the river’s mouth to the Gulf Stream. By going out every three months, researchers aim to capture any potential changes in each season of the year.

“Even though this is only giving us two years, the goal is to write grants to continue sampling further, maybe not to this level or this frequency, but just to have a better understanding of how the coast and offshore are connected,” Tolar said.

The Gulf Stream is a powerful current that originates in the Gulf of Mexico, curves around the Florida peninsula, up the Eastern Seaboard and extends toward Europe where it warms western European countries.

“But for our coastline, we know that it transports nutrients, it transports species up to our coast,” Tolar said.

The Gulf Stream oscillates and there is some thought that rising sea temperatures might actually weaken the current over time.

“We don’t really know what those consequences might be to what it transports up to our coast,” Tolar said. “If it’s transporting nutrients that feed our coastal habitats, which we care about a lot with our state’s blue economy, if it weakens or oscillates farther offshore rather than coming inshore, we would want to know.”

During each cruise, physical oceanographers will collect fine-scale water samples to get a sense of how the Gulf Stream current is moving and any changes in that movement over the course of a year.

Two, 20-minute-long fish trawls will capture as much fish as possible at each of the project’s six major stations, each of which include vastly different types of habitat. Researchers will count all of the species captured during the trawl sweeps, collect 10 of each species, and measure 30 of every species.

“This allows them to get a sense of the diversity of fish, the abundance of fish, and then their variability and size to see basically how fish communities change as we go offshore,” Tolar said.

Dr. Christian Briseño-Avena, a UNCW assistant professor of biological oceanography, plankton ecologist, and another principal investigator on the project, will collect zooplankton and larger phytoplankton to study how those organisms change over time.

“Eventually we’d like to know more about how the zooplankton, or the plankton in general, are changing or not changing for this region over longer periods of time,” he said.

Copepods “change a lot in this region,” he said. But samples of the tiny crustaceans collected from this region are sparse.

Briseño-Avena said he is learning as he goes on each expedition, targeting smaller plankton, fish larvae and zooplankton scooped up from the seafloor to the surface in “bongo nets,” aptly named because they are shaped similar to the open bottomed hand drum.

During TEAL-SHIPS maiden cruise earlier this month, he was met with some surprises when the bongo nets surfaced back aboard the R/V Cape Hatteras, a 135-foot oceangoing research vessel used as a hands-on training tool for marine technology students at Cape Fear Community College.

He wasn’t expecting to see in the winter what turned out to be a large amount of ichthyoplankton, which are the eggs and tiny larvae of fish.

His students have already begun the tedious task of extracting and identifying the different groups and species of plankton he collected. The plankton will be preserved in ethanol and used to build a library-like catalogue of samples that will be available to future coastal marine scientists.

He and Tolar agree the expedition was a success, despite the weather challenges that cut the initial trip by a half day and covered four of the six stations. The ship traveled just under 75 miles offshore, making it to the Gulf Stream where the water temperatures were 30 degrees warmer than those near shore.

“At least we confirmed if we were able to do as much as we did in our 18-hour weather window we’ll be fine for our future expeditions,” Tolar said. “We’ll have no problem getting all the way out there. We learned that we could do it and we learned how to be more efficient about it.”

UNCW’s Center for Marine Science is in the process of acquiring its own, larger research vessel. The 73-foot vessel is expected to be complete in the spring of 2026. TEAL-SHIPS project principal investigators hope to use the new vessel during their final two expeditions covered by the current grant.

Tolar hopes to tap additional funding sources for the program to collect samples beyond two years.

“If we’re able to get more funding in the future we can compare the changes year-to-year,” he said. “Even if not, we have a really nice study that shows this is what’s happening here off the coast of Wilmington and that can connect how other folks along the East Coast are measuring their samples.”

You have probably seen someone do a little happy dance when they spot their waiter heading to the table, entrée in hand. Turns out, sea turtles have the same reaction to the promise of a full belly.

University of North Carolina Chapel Hill researchers found that captive loggerheads could be conditioned to “dance” by associating certain magnetic fields with being fed food. This test allowed the researchers to test if they use the magnetic fields like GPS, a compass or both.

The study, “Learned magnetic map cues and two mechanisms of magnetoreception in turtles,” was published Feb. 12 in the science journal, Nature. Magnetoreception means that an animal can perceive the Earth’s magnetic fields.

Lead author Kayla Goforth is a recent doctoral graduate from UNC and is currently a postdoctoral fellow in the biology department at Texas A&M University.

For the study, the team conditioned different groups of 2-month-old turtles over the course of two months to differentiate between magnetic fields. The team replicated in the lab magnetic fields that exist along the Atlantic coast, from Canada to the Gulf of Mexico.  

“Every other day they would experience one specific magnetic field in which they were fed. On the days they were not fed, they would experience a second magnetic field, but they did not receive any reward in this field. Eventually turtles begin to exhibit the ‘turtle dance’ in the field in which they were fed,” she said.

“The turtle dance is a food-seeking behavior that is characterized by the turtle lifting its head out of the water, opening its mouth, alternating its flippers and spinning,” Goforth said. “It’s super adorable.”

To produce the different magnetic fields, the team used magnetic coil systems. A magnetic coil is a large frame with wire wrapped around it, horizontally and vertically. When an electric current runs through the wires, a magnetic field is created inside the coil system, and “by increasing or decreasing the amps running through the wire, we can change the magnetic field.”

At the end of the conditioning period, the team tested the turtles in both magnetic fields and found that turtles danced more in the field in which they were fed.

“You can think of it like training a dog,” Goforth explained. “If you always ring a bell when a dog is given food, eventually they will begin to expect food when the bell is rung, and salivate or beg.”

The team then investigated the mechanisms underlying the turtle’s magnetic senses.

“Turtles have both a magnetic map and a magnetic compass. A magnetic map is a positional sense, like a GPS, while a compass provides directional information,” she said, and both are required for navigation. A map tells you where you are or where you want to be and a compass helps guide you.

For this part of the study, the team tested both the turtle’s magnetic map sense and magnetic compass. Meaning, the turtles had to recognize a magnetic field and had to orient in a specific direction.

“We tested whether these two senses were disrupted by radiofrequency fields,” she said, because these fields are expected to disrupt chemical magnetoreception, which is a theory that suggests complex chemical reactions enable animals to detect magnetic fields.

The team found that the compass sense likely relies on chemical magnetoreception.

“The map sense, however, does not seem to rely on chemical magnetoreception. This means these two magnetic senses, while similar, are distinct. Just like seeing and hearing are two distinct senses,” she said.

Goforth explained that the idea for the study sparked from the well-known fact that sea turtles return to where they were born to reproduce, “but what is less well known is that turtles also display really strong fidelity to their feeding sites, meaning they consistently return again and again.”

How turtles learn the locations of those feeding sites is unknown but the team thought that they likely use magnetic fields.

“A missing piece of this idea though was that we did not know whether turtles could learn magnetic fields, so I decided to try conditioning, or training them to do so,” Goforth said. “We were really excited when it worked, and that assay then opened the door for studies into the mechanisms underlying the magnetic sense.” An assay is a procedure in a lab.

The findings answered two questions: if sea turtles can learn magnetic fields, and if the magnetic map and magnetic compass senses of turtles rely on the same underlying mechanism.

And while the findings answered those two questions – yes and no, respectively — it brought up another: “How sensitive are turtles to magnetic map information, i.e., what is the smallest difference in magnetic fields they could distinguish between? And,” Goforth said, “the next big question is, if the map sense does not rely on chemical magnetoreception, then what is the underlying mechanism?”

Goforth conducted her doctoral research in Chapel Hill’s the Lohmann Lab, run by married couple and biology professors, Kenneth and Catherine Lohmann.

“Kayla began to wonder if we could get the turtles to associate the magnetic signature of a geographic area with food — and therefore act out this turtle dance behavior,” Kenneth Lohmann said in a press release from the university. “She really took the lead in this. I wasn’t at all sure in the beginning whether it would work, but we were happy to have her try, and it turned out remarkably well.”

Goforth said she began researching sea turtles while working on her undergraduate degree at the University of Florida in Gainesville.

“I’ve loved the ocean since I was young, and from the time I was about 5 years old, I was determined to become a biologist,” Goforth explained. “In high school I attended a sea turtle camp in North Carolina and that is what led me to pursue sea turtle research in college. I found them fascinating, and wanted to know how they were returning to the same nesting beaches every year, which is what drew me to Ken’s lab at UNC-Chapel Hill.”

Dana Lim is another doctoral student in the Lohmann Lab studying the function and mechanisms of magnetic sensing in sea turtles.

She assisted Goforth with the study by helping test the effect of radiofrequency fields on the orientation of hatchling sea turtles and with conditioning the turtles to “dance” in the lab.

“Something worth noting about all of these experiments is just the immense amount of work and time that went into them,” Lim said, adding that conditioning the turtles was not easy. For each set of turtles, the team had to commit several hours per day, every day, including weekends, for two months.

Lim continued that the behavioral test used for this research “has been a mainstay in studying sea turtle magnetoreception for decades. However, it requires turtles to use both their magnetic map and compass simultaneously and is carried out at a field site with wild sea turtles. Being able to create a behavioral assay that isolates use of the turtle’s magnetic map in a laboratory setting is a huge step forward in studying the different parts of this key sensory system.”

The payoff is evident “in this very paper,” she said, since it allowed Goforth to test and find evidence for two different mechanisms underlying the map versus the compass in sea turtles.

“This has been a major question in the field of magnetoreception and evidence for multiple magnetoreception mechanisms in a single animal has only been shown a couple of times before this,” Lim explained.

Tara Hinton, an environmental Studies student in her last semester at Chapel Hill, collaborated with Goforth on the research during summer 2022 in Melbourne, Florida.

“Our days began early with beach patrols for loggerhead sea turtle nests, followed by outdoor work in the Florida elements to construct a magnetic coil for our study. When the sun set, we transitioned to night experiments, fueled by Oreos and plenty of coffee,” Hinton said. “It was a rewarding experience to work with some of Earth’s most remarkable magnetic navigators, alongside a team of passionate and dedicated researchers.”

Undergraduate students who spent their fall semester studying Currituck Sound may have broken new ground in understanding the effects of controlled burns on a marsh island.

For the project, students compared vegetative changes to the marsh islands with the Audubon Pine Island Sanctuary and Center in Currituck County that have no history of recent fire, islands that are occasionally burned, and islands that have had frequent controlled burns.

The students presented their findings “The Sound of Change: Responses to Controlled Burning and Other Changes in the Currituck Sound,” Dec. 12 as part of the monthly Science on the Sound lecture series at the Coastal Studies Institute, or CSI, on East Carolina University’s Outer Banks Campus.

The students conducted the research project as part of the Outer Banks Field Site, or OBXFS, a semester-long, University of North Carolina Chapel Hill undergraduate program hosted each fall by CSI.

Controlled burns are part of a fall tradition that existed well before the first European set foot upon the North American continent and “has deep historical roots in the South, where the practice was quickly adopted from the Indians by early European settlers,” according to U.S. Fish and Wildlife Service research.

While there have been a number of studies examining how a controlled burn effects a marsh, delving into a fire’s impact on invasive species, soil accretion, plant diversity and potential of endangering some animal species, this research takes a different approach.

The study “was one of the few that worked in brackish marshes, and the students talking to stakeholders and users of the marsh about the changes they perceived is also something that’s, I think, unique to the study,” Outer Banks Field Site Director Lindsay Dubbs said during the presentation.

The students included a human dimension and interviewed people who use the Currituck Sound frequently about the environmental changes they feel have taken place.

For their field work, the students traveled to marsh islands within the boundaries of the Pine Island site and compared the effects of controlled burning on marsh vegetation.

The islands were divided into three groups. The control islands had “no historical data of any burns happening,” explained sophomore Lily Bertlshofer. “Our occasional sites were last burned in 2021 and our frequent sites have data being burned every year.”

The study was designed “to look at how controlled burns impact the allocation resources within marsh plants and soils, the impacts of controlled burning on the vegetation community of marsh and what the implications for marsh resilience are,” Berlshofer said.

The study confirmed that the long-established practice of prescribed burns benefit vegetative diversity in marsh inlands.

At first glance there does not appear to be a significant difference in plant diversity among the three areas.

“We found that there was no statistically significant relationship between species richness and burn frequency,” said Veronica Cheaz, a sophomore.

That finding was expected. Because the number of plants that can live in a salt-to-brackish environment is limited, diversity is relatively low.

“Generally, we found low species richness at all of our plots, which is not very surprising,” Cheaz said. “We have a brackish marsh in the Currituck Sound, and there’s not going to be very many species.”

What the study did identify, though, was how effective controlled burning of a brackish marsh could be in maintaining the habitat.

“We also looked at salinity tolerance,” Chaez said, which “is going to be influential in determining how effective these sites are at adapting to environmental stressors like sea level rise and a rise in salinity. We found that occasionally burned sites had the highest scores compared to our control sites, and we hypothesized that this is because occasionally burned sites have a balance of the disturbance periods and restoration periods that allows salt water species to move in.”

There was at least one surprising finding. When the living root systems, or the biomass, of the three sites were compared, the frequently burned areas have statistically greater biomass than either the control or occasional burn areas.

Pointing to a graph showing more than double the biomass of an occasional site, senior Katelin Harmon, majoring in environmental studies and political science, described the finding that “frequently burn sites were much higher,” as “one of our most interesting findings…There’s much stronger root systems in our frequently sites.”

Verdant and complex, the Currituck Sound marsh is somewhat unique. The nearest saltwater source is Oregon Inlet some 55 miles to the south of the study area at the Pine Island Audubon site. The salinity there is typically under 3 parts per thousand, or ppt, and at times lower.

“The low salinity makes these places special, and we refer to that as an oligohaline environment,” junior Thomas Ferguson said during the presentation.

Currituck Sound has not always been an oligohaline, or a low-salinity, environment. Throughout the colonial period and into the early 19th century, there were two inlets on the north end of the sound. Currituck Inlet across from Knotts Island was open until the 1730s. New Currituck Inlet just to the south, opened soon after that, closing in 1828. Until New Currituck Inlet closed, the north end of the sound was a high-saline brackish marsh.

With the closing of the inlets, Currituck Sound transitioned to an oligohaline marsh and migratory waterfowl began arriving by the hundreds of thousands, creating a hunter’s paradise.

“In 1828 the Currituck Inlet, at that time composed of salt water, was closed by a storm and the vicinity gradually became fresh water. This change allowed vegetation such as wild celery and eel grass to grow on the marsh bottom and this new vegetation attracted wintering fowl in greater quantities than before,” The National Register of Historic Places noted in its assessment of the Currituck Shooting Club.

The Currituck Shooting Club, founded in 1857 “by a group of business men in New York City,” the assessment wrote, was the first of numerous hunting clubs that lined the shores of Currituck Sound. The building was completely destroyed by fire in 2003.

The Pine Island Club was formed in 1910. In 1979 the last private owner of the club, Earl Slick, a Winston-Salem developer, donated 2600 acres of marsh and uplands to the National Audubon Society. In 2009 Audubon North Carolina assumed full-time responsibility for the managing the club.

Hunting is still allowed on the property, but according to at least one of the hunters the student researchers interviewed, it falls well short of what it had once been like.

“It really doesn’t have any ducks compared to when I was young, when I was your age, this place had ducks. This place doesn’t have anything anymore,” the researchers were told.

In a question-and-answer session following the presentation, Pine Island Site Manager Robbie Fearn noted that the statistical biomass findings at the frequently burned areas was inconsistent with what was visually happening.

“I’m at the Pine Island Sanctuary,” he said. “The areas that are frequently burned from my lived experiences are falling apart, and yet the data says that for longer term management, frequent burning may be better… Is it a question of the plants are responding to the frequent burn by trying to survive and creating more below-ground biomass.”

For Fearn, who was very complimentary of the work the students did, the inconsistency between what he has observed and what the statistics say is a jumping off point for much needed further research.

“The work that these students have done have really set us up to dig in and figure out how best to manage these marshes in the sound and I’m very thankful for their work,” he said.

Coastal Review will not publish Jan. 1 in observance of New Year’s Day.

The last “Science on the Sound” for 2024 will give the public an opportunity to learn more about an undergraduate research project on elements of the Currituck Sound.

University of North Carolina Chapel Hill Institute for the Environment’s Outer Banks Field Site students are scheduled to present their findings at 4 p.m. Thursday, Dec. 12, in the Coastal Studies Institute on the East Carolina University Outer Banks Campus.

Science on the Sound is an in-person lecture series that brings perspectives from all over the state and highlights coastal topics in northeastern North Carolina. The public is welcome to attend the about 90-minute program at no charge. It will also be live-streamed on the CSI YouTube channel.

Outer Banks Field Site program is a semester-long, interdisciplinary residential learning experience for undergraduate students hosted by the Coastal Studies Institute. Each fall since 2001, the students have spent the semester taking classes, engaging in internships with local organizations, and completing a Capstone research project as a group.

This year, the students addressed for their Capstone research project the elements of the Currituck Sound, including how prescribed fire is used as a management tool in marshes and how different stakeholders think about Currituck Sound and their place in it, including the changes they have observed and experienced.

After a year of record coastal flooding, eastern North Carolina may feel a slight reprieve from high-tide flooding days between now and April 2025.

The National Oceanic and Atmospheric Administration’s National Ocean Service last week released its 2024-25 Annual High-Tide Flooding Outlook, which projects slightly fewer of these flooding days through spring 2025 than last year. That’s because El Niño conditions are transitioning to La Niña conditions, and these two opposing climate patterns in the Pacific can affect weather worldwide.  

“Bottom line: Over the past year, we’ve seen record coastal flooding, or high-tide flooding, along our coastlines,” Nicole LeBoeuf, National Ocean Service director, during the Aug. 6 online news briefing, said. “When the ocean runs hot, sea levels run high, and we see that playing out in our coastal flooding data.”

The outlook recaps high-tide flooding events from May 2023 to April of this year at 97 NOAA tide gauges along the U.S. coast, and it projects what to expect at these locations through April 2025.

High-tide flooding, which is sometimes called nuisance or sunny-day flooding, happens when tides reach anywhere from 1 to 2 feet above the daily average high tide, and cover what is typically dry land along the coast. “As sea levels continue to rise, high-tide flooding occurs more frequently, even without severe weather,” she said.

For the 2023-24 season, coastal communities in the United States experienced seven to eight flood days, LeBoeuf said. In 2023, 34 locations broke or tied their records for flood days, which she called “a dramatic increase” from the previous year.

Hot ocean temperatures led to the highest levels of sea level measurement on record. There were 44 NOAA tide gauge locations, mostly on the East Coast, that broke or tied their previously recorded sea levels to date. This means “we got an additional 6 inches of sea level rise and five median coastal flood days annually compared to the year 2000, roughly a 200% increase,” LeBoeuf said.

The recurring climate pattern called El Niño contributed to the record-breaking 2023-24 observations.

“El Niño typically raises ocean temperatures and can result in more frequent and intense storms hitting the coastlines, especially along the East Coast, where we saw many records break this past year,” she said. “With sea level rise and high-tide flooding increasing, El Niño simply makes things worse for coastal communities, home to almost 40% of the U.S. population.”

Because high-tide flooding can degrade infrastructure, damage property and disrupt coastal ecosystems and people’s daily lives, NOAA works to help communities predict this kind of flooding and its potential impacts, she said.

NOAA maintains the tide gauges across the U.S. and its territories that make up the National Water Level Observation Network. Some of the gauges have been recording water-level data for more than 150 years. Through this network, “NOAA monitors the unrelenting creep of sea level rise and the rapid increase of high-tide flooding,” LeBoeuf said.

The outlook brings together data about high-tide flooding events between May 2023 and April 2024. That time frame is used to “account for increased sea levels in the fall and increased stormy weather during winter months, so that we can most effectively predict the year ahead,” she continued.

There are four National Water Level Observation Network stations on the North Carolina coast. According to the annual outlook, Duck experienced 22 high-tide flood days between May 2022 and April 2023 compared to 13 the year prior. Oregon Inlet Marina encountered seven days, up two from the previous year’s five. High-tide flood days at the Duke University Marine Lab at Pivers Island in Beaufort increased from six to 11. At the Wilmington tide gauge, high-tide flood days increased from two to three.

“Almost every location we measure between New York and Georgia broke their sea level and flood-day records in 2023. It’s like El Niño had the US East Coast in its Bullseye,” she said.

In the coming year, NOAA projects that the country’s coastal communities will see a median range of four to eight high-tide flooding days between May of this year and next April, which she said is slightly down from last year “as we move away from El Niño and into La Niña conditions.”

The outlook projects that for Duck, there will be nine to 15 high-tide flood days, four to seven at Oregon Inlet Marina, four to six at Duke University Marine Lab in Beaufort, and two to six in Wilmington.

NOAA’s National Ocean Service researchers predicted that this year’s Atlantic hurricane season will increase the chance of significant flooding in some places, particularly along the Atlantic and Gulf coasts.

Hurricane predictions are not directly factored into NOAA’s high-tide flooding outlooks, but the product “can provide situational awareness regarding baseline flooding that can compound the impacts from real-time weather events like hurricanes and tropical storms” she said. “Events like hurricanes get a lot of attention, but high-tide flooding is one of the most tangible impacts of long-term sea level rise, reminding us that while we brace for impact today, the United States must also plan for a wetter future.”

NOAA scientists project that communities across the nation will experience an average of 45 to 85 high-tide flood days per year by 2050, which means that “every four to eight days, Americans along our coast will face disruptive and damaging seawater inundation regardless of the weather at the time.”

The federal agency also produces a Monthly High Tide Flooding Outlook to provide flooding likelihoods each day of the year, up to a year in advance, offering windows of time where there’s increased flood risks.

“Together, these outlooks complement one another with information across time scales to protect lives, ecosystems and economies as towns, states, tribes and businesses are faced with increased coastal flooding,” LeBoeuf said.

Coastal Ecologist Dr. Christine Voss, who recently retired from University of North Carolina Institute of Marine Sciences based in Morehead City, in response for comments about this high-tide outlook, explained that the trends in rising sea levels and the acceleration of global, regional and local water levels are sustained, and the data are clear. 

“If one examines the entirety of the data, there is some annual variation, yet the ‘big picture’ is unchanged. In its reports, including this one, NOAA makes clear that the Southeast US region, including coastal NC, is experiencing more high-tide flooding due to global sea-level rise, land subsidence, and regional oceanographic effects — compared to 2000 and the previous century,” she said in an email.

NOAA’s Aug. 6 article suggests that the expected development of La Niña is likely the reason that their models predict a lower number of high-tide flooding events from May 2024 through April 2025, compared to the previous year.

“So, this is the ‘regional oceanographic effects’ part of the equation. There are also numerous astronomical harmonic constituents that cause variation in our water levels,” Voss said. “Some of these harmonics have a period of up to almost 19 years,” pointing to the harmonic constituents at the NOAA Beaufort, Duke Marine Lab gauge and the Wilmington gauge.  

“Regardless of the flux in water levels, the major trend is the continued rising of sea levels and an acceleration of this trend. We, along the NC coastal region, need to proactively prepare for higher sea levels and do what we can to slow climate change,” Voss continued.

MOREHEAD CITY – There probably are relatively few people who understand the importance that the U.S. military, particularly the Marine Corps, places on understanding and protecting the environment of the land and water it uses.

Hans Paerl, professor of marine and environmental sciences at the University of North Carolina Institute of Marine Sciences in Morehead City, is one of them. He and colleagues from UNC and other universities are preparing to publish a paper that will outline the results of a multi-year study they conducted in and around the New River, which flows as an estuary through Marine Corps Base Camp Lejeune, then enters Onslow Bay in the Atlantic Ocean through New River Inlet.

The overall study, funded by the government, looked at the terrestrial portion of the area as well as the aquatic, and Paerl’s portion mostly involved quantifying the carbon and nutrient flows through what’s technically called “the freshwater-marine continuum of a temperate, micro-tidal estuary.”

Carbon, of course, is the building block of life as we know it. But carbon dioxide, or CO₂, the main greenhouse gas that most climate experts believe traps the Earth’s heat and is leading to significant changes in the climate, including sea level rise. And because Camp Lejeune and many other Marine Corps bases are near coastal waters – Marines are the nation’s amphibious fighters, and need to train in and around those waters – sea level rise and coastal habitat changes are important to them.

“They want to know what’s going on, on their properties and around them,” Paerl said. “And they want to know what their role is in what’s going on.”

Part of that is economic, part of it is planning.

“Many of the generals and others at the top are very forward-thinking,” Paerl said. “They can look down the road and see that at some point in the future, there might very well be carbon regulations and taxes. They want to know where they stand.”

In Lejeune’s case, Paerl said, the base is in pretty good standing. The study shows that 85 percent of the “nutrient budget” in the estuary – carbon is a nutrient, as are such things as nitrogen, phosphorus, potassium and calcium – comes from upstream, not from the base.

The river, which is only about 50 miles long and entirely contained in Onslow County, rises in the northwestern region and flows east-southeast past Jacksonville, where it widens into a tidal estuary about 2 miles wide. But before it gets to Jacksonville, it flows through mostly rural and agricultural land. That agriculture includes not only row crops, but also many hog farms with millions of hogs and their necessary waste lagoons. Nutrients abound.

So, Paerl said, it’s not surprising that the estuary’s nutrient load mostly comes from upstream, and the military officials are surely “delighted” to know that.

“What it means is that if we start getting more nutrient regulations, they’re in a pretty good position to show that they are not primarily responsible” for the problems that cause the need for regulations, Paerl said.

And there are plenty of examples of regulations arising from water quality problems. The state declared the Neuse River “nutrient sensitive” in the 1980s, after numerous algae blooms and fish kills, and developed and implemented rules designed to regulate sources of nutrient pollution in the basin, including wastewater, stormwater and agricultural runoff. The rules also require vegetative buffers along the water.

But beyond that, Paerl said, the Marine Corps and other branches of the military are concerned about climate change. At Camp Lejeune, they want to protect and maintain their ecosystem, because it’s similar to conditions in many areas of the world that Marines might have to fight. So they need to train in that ecosystem. Sea level rise and other ramifications of climate change could threaten those training grounds.

And, Paerl noted, military officials have long been concerned that an increasingly less stable climate with more droughts that disrupt food supplies, more major storms and continually rising sea levels, will create less stability in other countries, possibly leading to more need for U.S. intervention. They’re interested, perhaps more than most politicians these days, in limiting climate change.

What did the study find out specifically about organic, or vegetative, carbon and carbon dioxide, that predominant greenhouse gas, in the New River estuary?

Interestingly, Paerl said, it turns out that the estuary is, in general, pretty balanced between being a carbon sink, or holding carbon so it’s not released as carbon dioxide, and a contributor of CO₂ to the atmosphere.

“But that can change year-to-year,” he said. It turns out that much of that variation is related to weather, which is affected by climate.

“What we’ve found is that when we have major perturbations, chiefly storms, much more CO₂ is released,” Paerl said. “There were five or six major perturbations (during the study period), and we had the opportunity to look at (the effects) of those.”

What they’ve found is that “you can lose almost as much carbon to the atmosphere” from one major storm as had been stored away, or “fixed” by plants, in the estuary during the entire year in which the storm occurred.

“It’s kind like a gigantic ‘burp,’” the scientist said, that can, instantly negate a year of carbon storage by the algae and other plants.

Algae, another area of expertise for Paerl, can be terribly bad for estuaries, as it robs the water of oxygen when it decomposes, sometimes leading to fish kills. But, Paerl quipped, “I don’t think storms are really a good way to clean up our estuaries.”

At any rate, it sets up what Paerl said is a classic feedback loop.

“The more storms we have, then (based on the research) the more emissions we get,” he said. “And the more emissions we get, the more unstable the climate is likely to become, which means more storms. You have to wonder where it ends. Are we eventually to going to end up with 10 times more storms?”

It’s not, of course, “a perfectly linear world,” Paerl acknowledged, as there are other factors, such as El Nino, that influence the number of hurricanes and other storms. But you have to look at it not just from one year to the next, but decade by decade.

The New River work pretty much confirmed what previous work by Joseph Crosswell, also of UNC-IMS, found previously through work in the Neuse River, the largest tributary of the huge Pamlico Sound estuary, Paerl said.

The bottom line, he added, is that estuarine systems are very effective at holding carbon, unless disturbed. Some carbon even comes out and is “stored” by humans, through harvest and consumption of seafood.

But when those storms do hit, the negative atmospheric carbon effects can be quick, as in the windy Hurricane Irene in 2011, or slower and more sustained in the case of other, less windy storms that are mainly rainfall and flooding events.

Paerl said the overall study was funded by the Department of Defense’s Strategic Environmental Research and Development Program, and has been headed by RTI International, an independent, nonprofit research institute based in the Research Triangle Park. Other researchers have come from private companies, as well as from Duke University, the National Oceanic and Atmospheric Administration, the College of William and Mary and the Virginia Institute of Marine Science.

“It’s been a big effort, with a lot of parts,” Paerl said, and he credits the Department of Defense for being interested.

“They are really pretty good stewards of their environment, and it makes sense for them to be,” he said.

Paerl noted that the military also help preserve habitat outside the base gates by sometimes giving money to local governments to protect properties in the flight paths of Marine Corps aircraft that would otherwise be developed.

That’s happening now in Carteret County, where Emerald Isle is working with Marine Corps Air Station Cherry Point officials to get money to help pay for the purchase of 30 acres of undeveloped land behind the town hall. That property, mostly maritime forest, has been zoned for years for more than 200 condominiums, and is in the flight path of planes going to and from nearby Bogue Field, an auxiliary landing strip for Cherry Point.

If the town gets the land, it will preserve up to 20 acres of it.

“A lot of people don’t realize how much they do,” Paerl said of the Marines. “It was good to work on this project to try to help them identify what’s going on in the estuary that runs through (Lejeune).”

And, he said, the study aids the cause of science and scientific research, which has recently been under attack in some circles, because the modeling involved should be applicable to not just other coastal military installations, but to similar estuarine systems that aren’t in government hands.

“We’ve learned a lot,” he said.
