Trawling for trash: Using recycled shrimp nets to remove marine debris

UGA Marine Extension and Georgia Sea Grant has come up with a creative way to clean up the Georgia coast and provide financial support to local commercial shrimpers whose income was limited during the pandemic.

Through Trawl to Trash, funded by the National Sea Grant College Program, commercial shrimpers are recruited to sew bags made of recycled shrimp net material that can be used to collect marine debris.

“It’s exciting to find a new purpose for these trawl nets and who better to make the bags than the shrimpers who have spent countless hours mending their nets ahead of shrimping season?” said Dodie Sanders, marine educator at Marine Extension and Georgia Sea Grant, and lead on the Trawl to Trash project.

The shrimpers earn $20 for each bag they sew.

One fisherman, Jonathan Bennett, used the money he earned from the nets to pay the people working for him.

“It was extra money, it helped us out,” said Bennett, a fifth-generation commercial shrimper from Brunswick, who now captains his own boat, the Flying Cloud. Bennett has been shrimping since he was four. His grandfather taught him how to repair the shrimp nets.

“For years I was the only man on the boat who knew how to sew so I got pretty good at it,” he said. He and his grandfather, who is still a shrimper, joined the Trawl to Trash project during the off season when their boat was being repaired.

In an effort to produce more bags for outreach efforts, Sanders teamed up with the South Carolina Sea Grant Consortium to recruit additional shrimpers into the program. As of January 2022, 15 shrimpers in both Georgia and South Carolina have earned a total of $30,700 for 1,535 bags.

“This opportunity came along at a great time, in that shrimpers are making the bags in between the peak of the brown shrimp season and white shrimp season, when landings and income are lower than the rest of the year,” said Graham Gaines, living marine resources program specialist at the South Carolina Sea Grant Consortium and partner on the project.

With more than a thousand bags in hand, Sanders and other educators at the UGA Marine Education Center and Aquarium on Skidaway Island have been working to distribute them to the public through education programs and community science efforts.

“We’re educating and engaging ecotour guides, students, recreational boaters beach goers and others who can make a difference by alleviating the impacts of marine debris,” Sanders said.

As part of their outreach effort, the team launched a Marine Debris Community Science Program, which engages volunteers in removing marine debris from barrier islands and salt marshes along the Georgia coast while tracking what they collect using the Marine Debris Tracker App.

Since April 2021, community scientists involved in the program have conducted more than 25 marine debris cleanups across three sites on the Georgia coast and collected thousands of items.

They are also working with ecotour guides who have been certified through Marine Extension and Georgia Sea Grant’s Coastal Awareness and Responsible Ecotourism program. The guides are providing bags to their customers and encouraging them to collect debris while exploring Georgia’s beaches and barrier islands.

This summer, educators will deliver hands-on afterschool programs to Boys and Girls Clubs in Chatham and Glynn Counties, educating the next generation about marine debris and encouraging them to make difference by using the Trawl to Trash bags to clean up their communities.

“These efforts illustrate and reinforce the importance of building community capacity and encouraging behavior change as a way of supporting the long-term prevention of marine debris,” Sanders said.

UGA creates stormwater management tools to help reduce flooding in coastal communities

Fact sheets, checklists and a video created by faculty at the University of Georgia Marine Extension and Georgia Sea Grant are helping coastal communities invest in green infrastructure that protect areas from flooding and pollution from stormwater runoff.

In the first year of their development, eight communities, or 44% of the municipalities in coastal Georgia that are regulated to protect water bodies, have used the tools created by Marine Extension and Georgia Sea Grant, a UGA public service and outreach unit.

With funding from the U.S. Environmental Protection Agency, Jessica Brown, stormwater specialist at the Marine Extension and Georgia Sea Grant office in Brunswick, partnered with Goodwyn Mills Cawood, an architecture and engineering firm, to produce a video highlighting the role of green infrastructure in coastal Georgia, factsheets on the most common green infrastructure practices, and inspection checklists to be used by professionals who maintain those practices.

“There is a lack of visual guidance and local, coastal examples of green stormwater infrastructure,” Brown said. “These tools help bridge that gap.”

Roads, buildings and parking lots that are impervious can lead to stormwater runoff and exacerbate flooding issues on the coast. When communities invest in green infrastructure, like installing permeable pavement or creating neighborhood rain gardens, they become more resilient.

According to the 2017 Coastal Georgia Low Impact Development Inventory, there are 220 green infrastructure practices in Georgia’s 11 coastal counties that manage 89.3 million gallons of stormwater annually. More than 94% of those green infrastructure practices are in the eight municipalities that are using the tools.

“We’re having to really rethink how we’re planning for our communities for the long haul,” said Jackie Jackson, director of advance planning and special projects with the Chatham County-Savannah Metropolitan Planning Commission. “In Chatham County we’re faced with planning for saltwater intrusion, we’re seeing things that are impacting our waterways and tree canopies, and we throw that on top of huge issues with localized flooding and more and more storms.”

“We’re kind of at that tipping point where we’ve got to start doing something different, and these are tools that we can use to start making some of those important changes.”

Since the work is often carried out by maintenance staff in public works departments, Brown, created the user-friendly tools with them in mind. Jackson helped Brown gather feedback from public works staff as the factsheets and checklists were being developed. She then worked with the cities of Bloomingdale and Garden City to incorporate the resources into their stormwater management plans, which led to the tools being approved by the state of Georgia for these coastal communities.

“All inspection forms have to be approved by the state and the state agreed that these tools will work,” Jackson said. “The end product is something that the state of Georgia actually permits communities to implement, so it becomes a win-win for everybody.”

The tools are free and available to anyone interested in learning about or implementing green infrastructure practices. They are available at https://gacoast.uga.edu/stormwater-management/

Phytoplankton monitors help keep communities safe from harmful algal blooms

Every Thursday, a group of dedicated UGA Marine Extension and Georgia Sea Grant volunteers collect water samples from the Skidaway River. They process the samples in the lab at the UGA Aquarium, counting and identifying the phytoplankton in each sample as part of the National Phytoplankton Monitoring Network (PMN).

“I absolutely adore it,” said Sandy Haeger, a PMN volunteer. “Thursdays are really special to me because I love getting to see the marine animals at the aquarium, collect data with the team and catch up with the staff.”

Volunteers look at water samples under microscopes to find phytoplankton.

Phytoplankton are critical organisms that serve as the base of the marine food web and they provide at least half the Earth’s oxygen. In a balanced ecosystem, phytoplankton provide food for a wide range of sea creatures including shrimp, oysters and jellyfish. When too many nutrients are available, phytoplankton may grow out of control and form harmful algal blooms. These blooms can produce extremely toxic compounds that have harmful effects on fish, shellfish, mammals, birds, and even people.

The PMN program was created in 2001 by the National Oceanic and Atmospheric Administration (NOAA) as a system to monitor marine phytoplankton and the potential for harmful algal blooms. The network has 250 sites in 22 states across the U.S., including Skidaway Island, Georgia. PMN volunteers collect ecological data and send it to NOAA, state and federal agencies and industry professionals in true citizen science fashion.

“The more information we have, the better we can understand (algae blooms) and organisms and hopefully better protect people from their harmful effects,” said Jennifer Maucher, one of NOAA’s PMN program coordinators. “Our volunteers are instrumental in this effort.”

PMN volunteers gather a variety of important data used for long-term phytoplankton monitoring.

The monitoring program at Marine Extension and Georgia Sea Grant is one of the organization’s longest running volunteer efforts. Since 2003, volunteers have gathered data such as water and air temperature, salinity and tidal flow in addition to the water samples collected every Thursday morning. The volunteer program has been so successful that a new monitoring site was added in 2019 in Oglethorpe Bay, the waterway behind Marine Extension and Georgia Sea Grant’s Brunswick facility.

“These are not folks that came into this with the knowledge to do this monitoring. They were interested in contributing, and we do our best to support them through it,” said Katie Higgins, Marine Extension and Georgia Sea Grant’s volunteer coordinator.

Higgins works to ensure that each volunteer is trained in the data collection process before starting. They learn to collect samples by towing a plankton net for three minutes at a time. Then, they bring their samples into the lab and analyze them under a microscope where they look for 12 target organisms, or phytoplankton organisms with potential hazards. The volunteers will take the data they have collected and enter it into the national NOAA database for future analysis and studies.

“At the first meeting I attended, I hadn’t been near a microscope in almost 50 years, so it was a steep learning curve for me, but everyone was so helpful,” said Haeger. “Learning is so important, especially life-long learning which is what this volunteer program is for me.”

All PMN volunteers are given training in microscope usage and phytoplankton identification.

The life-long learning and citizen science component of the program is what makes it so special, Maucher, Higgins and Haeger all say. Regular people with an interest in scientific efforts, their immediate environment, public health and safety, or climate change and its effects can play a role in phytoplankton monitoring whether or not they have a background in it.

According to Higgins, one of the biggest successes of the PMN program is how volunteers have shifted into playing an education role within the organization. UGA Marine Extension and Georgia Sea Grant hosts a variety of educational public programs, some of which are tailored around teaching the general public, both adults and children, about phytoplankton monitoring.

On numerous occasions, volunteers like Haeger have taken the lead on teaching aspects of the programs since they are doing the work weekly and know firsthand its impacts.

“[UGA Marine Extension and Georgia Sea Grant] utilizes not just citizen scientist volunteers but incorporates PMN into their summer camps for kids,” said Maucher.

Anyone interested in being a part of this program is encouraged to join. To find out more about the Phytoplankton Monitoring Network volunteer opportunities, visit https://gacoast.uga.edu/phytoplankton-monitoring-network/

Community science supports environmental research

You don’t have to be a professional scientist with an advanced degree to make a meaningful contribution to scientific research. That is one conclusion of a recent paper by Dodie Sanders, an educator at the University of Georgia Marine Extension and Georgia Sea Grant, and UGA Skidaway Institute of Oceanography researcher Jay Brandes. The article was published in the winter issue of Current: The Journal of Marine Education.

The paper focuses on the researchers’ use of “community scientists” in a project to study the extent of microplastic pollution on the Georgia coast. The community scientists are volunteers, without extensive training or graduate degrees in the field.

The initiative began in 2018 when Brandes and Sanders were faced with the daunting task of collecting monthly water samples at 12 different sites along the Georgia coast, but without a large team to conduct the field work. The previous summer, a UGA undergraduate student, Jacob Mabrey, demonstrated that using community scientists to fill the gap might be the answer. Mabrey spent the summer traveling up and down the coast and collected dozens of samples.
Sanders and Brandes wanted to know whether community science could play a significant role in scientific research. They started with a model developed by the University of Florida microplastics project, Florida Microplastic Awareness Project.

“We took that model and adapted it to what we thought we needed here on the Georgia coast,” Sanders said.

Sanders and Brandes initially approached the Satilla, Altamaha and Ogeechee Riverkeeper groups, who conduct monthly water tests in their areas already. The riverkeeper groups gladly joined the project. Sanders and Brandes then expanded to include a small group of volunteers who were working with Marine Extension and Georgia Sea Grant on the Skidaway Island campus.

“It’s worked out great because we have a group of volunteers that are very interested in learning more about this global issue,” Sanders said. “But more importantly, they’re interested in doing something about it. And so, this afforded an opportunity for volunteers to come in and not only help us do the science, but also become advocates for the project and advocates for what we were trying to accomplish.”

Roger Cayer is one community scientist volunteer. “I feel like studies like this are important to raise the awareness level of the general population about plastic pollution,” he said. “Who would have thought that synthetic clothing would become such a major problem?”

Brandes is very careful to avoid using the term “amateur” to describe the team of volunteers. “I think, sometimes, there can be a negative connotation to that word, but the people who have been working on this project have been wonderful and very dedicated.”

He said that everyone involved understands the critical importance of proper research technique, strict protocols and training in order to obtain believable data.

The COVID-19 pandemic put a halt to the field work for the past 12 months. As Brandes said, it is difficult to socially distance on a 24 foot Carolina skiff.

Sanders and Brandes would like to see their work benefit other researchers and community scientists. The overarching concept of the article is to provide a model that other researchers can put to work elsewhere.

“Take community science, and its advantages, and its bonuses and how people can be an integral, an important part of scientific research, because they are force multipliers,” Sanders said. “They allow us to do so much more on such a larger scale than we would be able to do on a day-to-day basis.”

Sanders said the community scientists opened her eyes to how the public is interested in environmental issues, especially issues that are in their own backyard. And they want to be advocates.

“So that’s been a rewarding aspect of this project, to not only get to know the volunteers or the community scientists on a personal level, but to realize their passion for the work is just as great as our passion,” she said.

That passion is echoed by Cayer who said he has enjoyed “the camaraderie, the laughs, the sharing of knowledge and ideas. And getting to know each member on a deeper level by sharing a common passion and goals.”

New sustainable ecotourism certificate aims to protect shorebirds while supporting tourism

UGA Marine Extension and Georgia Sea Grant is partnering with the nonprofit Manomet Inc. to develop a new certification program for water-based tour companies that provides them with the tools to implement best practices when it comes to birding-related tourism activities.

Georgia’s beaches provide vital habitat for shorebird species throughout the year. Many of the more remote habitats used by shorebirds are also areas used by recreational boaters and serve as a destination for guided tours. Beachgoers enjoying the warming weather may unintentionally disturb shorebirds’ nesting, resting and feeding behavior. Increasing awareness among boaters and beachgoers on how and why to give shorebirds space is a key step in conserving these unique animals.

“These habitats are very important for nesting species and for migrating shorebirds who need to rest and refuel,” says Abby Sterling, shorebird biologist for Manomet’s Georgia Bight Shorebird Conservation Initiative and partner on the project. “Our objective of partnering with the ecotourism industry means that we can work together to increase knowledge and reduce disturbance by incentivizing responsible behavior through a marketable ecotourism credential to protect these truly special places we all love.”

The Coastal Awareness and Responsible Ecotourism program will consist of a series of workshops designed for the public and ecotourism operators who will receive a certificate after completing the program. The workshops will highlight the important role Georgia’s coast plays for nesting and migrating shorebirds and how residents, tourists and tourism companies can work together to protect these fragile habitats.

“The program will allow us to leverage protection of our wild Georgia coast while also supporting local small business tour operators,” says Katie Higgins, project lead and marine educator and volunteer coordinator at Marine Extension and Georgia Sea Grant, a UGA Public Service and Outreach unit.

“Ecotourism really provides an opportunity to build support for conservation action among coastal residents,” Higgins says.

The first workshop is scheduled for May 20 from 4-5 p.m. The event is open to the public but pre-registration is required. During the program, Higgins and Sterling will be joined by ecotourism operators Fran and Kathryn Lapolla of Savannah Coastal Ecotours who will talk about their experience running an ecotourism kayaking business.

Additional information and online registration for the event is available at https://t.uga.edu/5Xb

Manomet is a sustainability nonprofit grounded in science, named for the coastal village in New England where its headquarters have been located since the Manomet Bird Observatory was founded in 1969.

UGA’s new Green Living Series promotes conservation through individual action

Residents of Georgia’s coastal communities can learn how to save money and better preserve natural resources during “Green Living,” a new series of programs offered by the University of Georgia Marine Extension and Georgia Sea Grant in Brunswick this winter.

“Our goal is to help coastal residents realize how everyday actions, from picking up after pets to using reusable bags, not only saves money but also helps conserve and protect our vital coastal resources,” says Kayla Clark, public programs coordinator for Marine Extension and Georgia Sea Grant. “We know how much people value living in the Golden Isles. Our hope is to share some fun, innovative ideas for how they can help protect this area as well as the rest of the coast.”

From December through March, UGA Marine Extension and Georgia Sea Grant will offer sustainability-focused events, including a film screening, tips on how to save money by using less energy, the environmental impacts of animal waste, recycling habits, and a lesson in building a rain barrel.

New Adopt-A-Wetland coordinator plans to enhance monitoring efforts on the coast

Marine Extension and Georgia Sea Grant welcomed Luke Roberson as the new Adopt-A-Wetland program coordinator for coastal Georgia. Roberson is recruiting, training and coordinating citizen scientists who are interested in protecting the aquatic resources surrounding Georgia’s coastal communities.

“My job involves talking with people about stewardship of their local waters, the science of water quality, and traveling along our beautiful coast with a terrific team,” says Roberson. “What’s not to like?”

Roberson will work to increase public awareness of water quality issues by training citizen science groups in different communities on how to monitor water quality and conduct biological sampling to determine wetland habitat health. All the data that is collected will be compiled by Marine Extension and Georgia Sea Grant and added to the Environmental Protection Division’s water quality database maintained at the Atlanta Adopt-A-Stream office. Each group is provided with an annual report summarizing the data collected at their respective sites.

Roberson made his way to Georgia from Maryland, where he worked on the local rivers with the U.S. Fish and Wildlife Service and served as a biologist for eight years with the Maryland Department of Natural Resource’s Monitoring and Non-Tidal Assessment Division. Prior to his role at Marine Extension and Georgia Sea Grant, Roberson worked as the monitoring and education coordinator for the nearby Ogeechee Riverkeeper.

Roberson earned a bachelor’s degree in biology as well as graphic design at the University of Kentucky in Lexington. He then pursued his master’s degree in environmental science and policy from Johns Hopkins University in Baltimore, Maryland.
