The Coastal State Discussion Series is a forum dedicated to highlighting current scientific research, finding solutions, and building partnerships centered around coastal communities and environments.
The goal of these events is to bring together scientists, resource managers, professionals, students, and interested stakeholders to learn about ongoing marine and coastal-related research efforts throughout the state, and to generate ideas and collaborations that utilize this knowledge in a way that best serves coastal communities and the environment now and in the future.
This series is sponsored by Rhode Island Sea Grant with the support of the University of Rhode Island’s Coastal Institute, College of Environment and Life Sciences, and the Graduate School of Oceanography.

“Perspectives of Aquaculture and the Impacts of Climate Change on Recreation in Coastal Salt Ponds”
Dr. Tracey Dalton, professor of Marine Affairs at the University of Rhode Island, shared findings on what influences people to support or oppose aquaculture in Rhode Island waters. Her team’s findings will help to minimize conflict where possible, and help guide aquaculture practices.
Emily Patrolia, graduate student at the University of Rhode Island, has been working with Dr. Dalton to study the various uses of Rhode Island’s coastal salt ponds. She will be discussing the short- and long-term fluctuations in coastal recreation to help state managers and business owners better utilize resources and plan for the future.
“Ship Graveyards & Uncovering Our Maritime Heritage”
A look at Rhode Island’s largest ship graveyard and parallels with Mallows Bay.
David Robinson, a marine archaeologist at the University of Rhode Island Graduate School of Oceanography, discussed the historical and environmental values of 29 historic vessels discovered off Bold Point in Providence Harbor – including two iconic steamships, Mount Hope and Bay Queen and the implications for Providence Harbor.
Dr. Susan Langley, Maryland State Underwater Archaeologist, joined the discussion presenting work on the development of Mallows Bay, the largest ship graveyard in the nation and on the table to be listed as the next National Marine Sanctuary. She describes the history of these watercraft and how they ended up in Maryland, as well as how the site serves the area now, which may offer ideas about what could be for Rhode Island.
“Coming to America: The biology of marine debris from the Japanese Tsunami”
The Tohoku Earthquake and Tsunami of March 11, 2011 ejected a vast debris field into the North Pacific Ocean that began drifting toward North America and Hawaii. This allowed, for the first time, to track and study how invasive species may be transported over long distances via rafting on debris.
Since 2012, over 400 objects including docks, vessels, and buoys with more than 330 living Japanese species have been intercepted from Alaska to California and Hawaii. Searches for new potential invasions from tsunamis have begun in the Pacific Northwest and Hawaii. More than 4 years after the tsunami, living Japanese species on tsunami debris continue to arrive.
Dr. James Carlton,world-renowned expert in aquatic invasive species and professor emeritus of marine science at Williams College and director emeritus of the Williams College Maritime Studies Program at Mystic Seaport, discussed marine life discovered on Japanese tsunami debris along the West Coast, potential bioinvasions from natural disasters, and current invasive issues along the New England coast.
“Impacts of Climate Change on Septic Systems”
Jennifer Cooper, a Ph.D. candidate at the University of Rhode Island, will discuss how increased surface temperatures, changing precipitation patterns and sea level rise impact conventional septic systems and alternative technologies.
Cooper has been working Jose Amador, URI professor of natural resources and the team’s research leader, and George Loomis, soil scientist and director of the New England Onsite Wastewater Training Center at URI, to look at current designs and parameters for septic systems against various climate-change scenarios. Cooper, more specifically, has been investigating two types of alternative systems more commonly used in Rhode Island, which both utilize a pressurized shallow narrow drainfield (PSND) technologies that either applies an advanced treated wastewater using sand filtration or just the surface soil for treatment.
“Ecological and Economic Benefits of Certified Seafood”
Guest speakers Jeremy Collie, a fisheries ecologist and professor of oceanography at the URI Graduate School of Oceanography, and Hirotsugu Uchida, an assistant professor of environmental and natural resource economics at URI, will discuss the status and trends of various fish stocks, an examination of whether certification of fisheries sustainability by an organization, such as the Marine Stewardship Council, affects the sustainability of a stock, and whether a certified product commands a premium price, as expected.
“An Ounce of Prevention: Probiotics Hold Potential for Shellfish Disease”
Deep lacerations scar the shells of lobsters. Entire populations of oysters die in less than 24 hours. These are the results of disease, potentially caused by bad bacteria. And although bacteria may be the cause, in it also lies potential for a solution.
Can something as simple as a probiotic, the good bacteria, like the ones found in yogurt, help prevent, treat, or even cure these diseases?
Dr. David Rowley, associate professor of biomedical sciences and pharmaceutical sciences at the University of Rhode Island, has been studying the effects of probiotics — bacteria that promote disease-resistance — for reducing mortality rates in larval oyster.
He will discuss his current work with probiotic applications in oyster hatcheries that could have implications for Rhode Island’s shellfish aquaculture industry.
Dr. Kathy Castro, a fisheries scientist specializing in lobster ecology at the University of Rhode Island and who runs the university’s Fisheries Center, has been studying the effects of lobster shell disease.
She will be discussing ongoing work testing Dr. Rowley’s probiotic hypothesis to fight lobster shell disease that is thought to be linked to a new bacterium found in local waters. If the disease expands as rapidly in Maine as it did in Rhode Island, it could also have a dramatic effect on the iconic Maine fishery.
“The Role of Nitrogen in Ecosystem Functioning and the Impacts of Climate Change”
The nitrogen cycle seems simple. As a gas, it’s the most abundant element in the atmosphere, but can quickly be turned into organic nitrogen, ammonium or nitrate through fixation done naturally in ecosystems by microbes, then used as fuel for plants to grow.
But there’s a catch.
“It’s a lie. A total lie,” Robinson “Wally” Fulweiler says of the readily accepted nitrogen cycle theory.
Robinson “Wally” Fulweiler, an ecosystems ecologist and biogeochemist at Boston University, will discuss her work with energy flow and biogeochemical cycling of nutrients – specifically nitrogen and it’s impacts on coastal marine ecosystems. Her recent focus has been on how climate change may influence the nitrogen cycle in estuarine and shelf systems, and how anthropogenic impacts alter coastal nutrient cycles.
Bethany Jenkins, associate professor of oceanography at the University of Rhode Island Graduate School of Oceanography, will discuss her work in understanding how marine microbes are impacted by nitrogen cycling, and her DNA sequencing technique to characterize the assemblage of genes represented in a particular environment – with respect to nitrogen assimilation gene sequences.
“The Economics of Climate Change”
To any economist things are typically broken down into “tradeoffs.” What will I give up and what will I get in return? At least that’s what Robert Johnston, an economics expert from Clark University, said at the Coastal State Discussion Series on February 25, 2014 sponsored by Rhode Island Sea Grant] at the University of Rhode Island’s Kingston campus.
Johnston discussed various ongoing research efforts to look more specifically at the tradeoffs of coastal management in New England communities, and the potential costs associated with climate change. He said we can’t think about hazard adaptation in a box and isolate it from all the other management tradeoffs, noting that some of the key tradeoffs will be related to coastal development regulations.
