DV-19-05 Perfluorinated alkyl substances (PFAS) and phthalates in marine mammals found in the Gulf of Maine adjacent Canadian waters: relevance to human health

Dr. Sean Todd College of the Atlantic Perfluorinated alkyl substances (PFAS) and phthalates are persistent organic pollutants, toxic chemicals that are mostly resistant to degradation and can accumulate over periods of time in an environment. The effects of these toxins are unknown for marine mammals, but have been linked to developmental problems and immunosuppression in […]

DV-19-06 Effects of microplastic fibers presence and ingestion on American lobster larvae

Dr. David Fields Bigelow Laboratory Increasing concentrations of marine plastics and microplastics have been documented in the Gulf of Maine, due to an array of plastic pollution sources. Marine plastics and microplastics are known to be ingested by marine invertebrate species, including lobster, a commercially important species in Maine. Previous research on other invertebrate larvae […]

DV-19-07 Shell Day: Marine Monitoring Blitz

University of Maine Parker Gassett Ocean acidification refers to a decrease in the pH of seawater due to the absorption of CO2 from the atmosphere. An increase in atmospheric CO2 levels results in an increase of CO2 absorption and more acidic water. Shellfish, which contribute $56.0 million to the economy and 1,500 jobs for Maine […]

DV-19-08 Examining the efficacy of methods to enhance soft-shell clam recruitment along the Maine coast

Dr. Brian Beal Downeast Institute The soft-shell clam fishery is an important part of Maine’s history and culture. However, clam landings have decreased over the past decade due to warming water temperatures and predation by invasive species. In order to support sustainable seafood and coastal ecosystem health, investigators will test whether “brushing” is a viable […]

DV-18-12 Data compilation, analysis and visualization training for citizen scientists

Kathleen Thornton Darling Marine Center University of Maine Citizen groups, aided by new technologies such as autonomous buoys, sondes, and other hand held instrumentation, as well as an expanding network of volunteer monitors, are obtaining a steadily increasing volume of coastal and estuarine water quality data. Even as the amount of data increases, there exist […]

DV-18-13 Determining causes of replicate variability in levels of Vibrio parahaemolyticus in Eastern oysters in order to improve the efficacy of a cold water pathogen reduction process

Meredith White Mook Sea Farm Some of the greatest risks facing oyster growers in Maine stem from ecosystem changes including increased temperature and changes to seawater chemistry that affect abundance of Vibrio species, an illness-causing bacteria. Illnesses linked to consumption of shellfish from cooler northeast waters had historically been rare but has increased in […]

DV-17-21 Midcoast Maine Water Quality for Our Communities

Sarah Gladu Damariscotta River Association Damariscotta, ME The Maine Coastal Observing Alliance (MCOA) consists of nine coastal citizen monitoring groups who collect water samples and analyze pH, temperature, dissolved oxygen, nutrients (total nitrogen), salinity, and turbidity in eight coastal estuaries and embayments between Casco Bay and Penobscot Bay. This coastwide survey, initiated in 2013, of […]

DV-17-22 Bagaduce Watershed Monitoring

Bailey Bowden Town of Penobscot Alewife Committee Penobscot, ME There has been a lot of activity in the Bagaduce River watershed, including participation in the SEANET project and two fish passage restoration projects supported by NOAA’s Habitat Blueprint. New fishways at Pierce’s and Wight’s Ponds in Penobscot are part of a focus on restoring alewives […]

DV-18-01 Compared growth and physiology of American lobster and green crab under elevated temperature

David Fields Senior Research Scientist Bigelow Laboratory for Ocean Sciences The Gulf of Maine is warming at a rapid rate, with unknown consequences for marine life, including commercially and culturally important species such as American lobster and soft-shell clams. Previous work by Bigelow and UMaine scientists provided some of the first indication that temperature is […]

DV-18-02 Bagaduce Estuary fish population surveys

Bailey Bowden Town of Penobscot Alewife Committee Penobscot, ME The Bagaduce River Estuary is the focus of a watershed-wide effort to restore passage for sea-run fish and enhance ecosystem integrity, including participation in the SEANET project and NOAA’s Habitat Blueprint. The effort is led by the Town of Penobscot with support from Sedgwick and Brooksville, […]
