Application of Quantitative Molecular Methods to Characterize Abundance and Distribution of Alexandrium Cysts for NOAA’s HAB Forecasting

This project supports development for two lab-based quantitative molecular methods for more rapid, accurate detection of Alexandrium catenella resting cysts in sediment from the Gulf of Maine, Puget Sound, and the waters around Kodiak Island and Kachemak Bay, AK. Winter abundance of benthic Alexandrium cysts is used to predict severity ...

Applied Ecophysiology of Marine Aquaculture Species to Understand Environmental Interactions

Forecasting environmental interactions of marine aquaculture activities requires an in-depth understanding of the environment and the species farmed. We are investigating two promising candidates for marine aquaculture: red porgy and vermilion snapper. Like many fish within the Snapper–Grouper Complex of the South Atlantic and the Gulf of Mexico, these two ...

Aquaculture and Eutrophication in Long Island Sound and Great Bay – Piscataqua Estuary

Eutrophication is the overabundance of nutrients in a body of water that results in harmful algal blooms, fish kills, and in some cases ecosystem collapse. We are investigating the feasibility of using shellfish to filter out excessive nutrients in the Piscataqua estuary. Using models, field data, and input from stakeholders, ...

Aquaculture Mapping Atlas and FARM Model

We are integrating two tools commonly used to plan for and site aquaculture: the Farm Aquaculture Resource Management (FARM) Model and the Connecticut Aquaculture Mapping Atlas. This improved tool will help identify the places where aquaculture is compatible with other human uses and where adverse effects on wild species, habitat, ...

AquaSpace – An Ecosystem Approach to Making Space for Sustainable Aquaculture

Aquaculture is a large and growing segment of seafood production because capture fisheries production continues to decline. A major challenge to the expansion of marine aquaculture in most nations is siting and subsequent expansion of aquaculture operations. We are developing tools to address spatial planning issues relating to aquaculture in ...

Are Growth and Toxicity of the Dinoflagellate Alexandrium Controlled by Grazer-induced Defense?

Blooms of Alexandrium fundyense result in economic losses to fisheries, aquaculture, and pose public health risks. Typically, A. fundyense growth and toxicity are seen as dependent on light, temperature, and nutrients. New evidence shows that grazers (copepods, bivalves, sea squirts) induce toxin production and decrease growth rate. The tradeoff between ...

Are Marine Protected Areas Working in the U.S. Virgin Islands?

We used a decade of underwater monitoring data to evaluate the effectiveness of no-take and partial-take Marine Protected Areas (MPAs) located in the U.S. Virgin Islands in the context of differing levels of enforcement and compliance. Results will provide managers with a status report that can guide management actions and ...

Assessing Biogeography, Conditions, and Marine Protected Area Efficacy in the Dry Tortugas

In 2001, state and federal agencies established the Tortugas Ecological Reserve to protect extensive unspoiled shallow-water coral reefs that support a wide variety of marine life off the Florida Keys. The objectives of our project were to assess: the seafloor habitat and reef fishes of the reserve, the effectiveness of ...

Assessing Coral Bleaching in Four U.S. Caribbean Managed Areas

In 2005, high sea temperatures caused coral bleaching in the Caribbean. The goals of this this project were to characterize the spatial extent of coral bleaching and recovery and to monitor the effects of bleaching on coral reef ecosystems in four managed areas of the Caribbean. Why We Care Coral ...

Assessing Futiga Dump Site Impacts on Fagatele Bay in National Marine Sanctuary of American Samoa

This project will determine the potential impacts of the Futiga dump site and landfill on the coral reef ecosystem resources of the Fagatele Bay unit of the National Marine Sanctuary of American Samoa. Leachate from the landfill could be having adverse effects on marine organisms and a rigorous quantification of ...

Assessing Land Based Sources of Pollution in Tinian, Commonwealth of Northern Mariana Islands

Coral reefs are diverse, productive, and economically valuable ecosystem, but are threatened by a variety of stressors in including land based sources of pollution, such as nutrients, pesticide, heavy metals and sedimentation. The island of Tinian (CNMI) has a unique land use history that includes military activities, tourism and low ...

Assessing Social Values Relative to Offshore Wind Energy Areas in North & South Carolina

The Bureau of Ocean Energy Management’s (BOEM’s) Office of Renewable Energy Programs oversees development of offshore renewable energy projects on the Outer Continental Shelf (OCS). BOEM identified wind energy areas (WEAs) on the OCS of North Carolina, and was in the process of locating WEAs in South Carolina. To inform ...

Assessing Societal Impacts of Harmful Macroalgae Blooms in the Caribbean

This study will use a mixed methods approach to examine how Sargassum events and their mitigation in the Caribbean affect multiple dimensions of social resilience, including economic impacts, human wellbeing, local ecological knowledge, and individual attitudes, values, and behaviors. Why We Care In recent years, the number, distribution, and magnitude ...

Assessing the Ecological Function of Shipwrecks, Artificial Reefs and Rocky Reefs on the Southeastern U.S. Continental Shelf

Increased calls for enhancing ocean habitats through artificial reefs and proposals for increasing offshore energy development require science to understand the impact and habitat value of these artificial structures on marine ecosystems. Harnessing technologies, including fishery echosounders and remotely-operated vehicles, we collect and synthesize data on fish communities, benthic communities, ...

Assessing the Geographic Variability in Vulnerability to Climate Change and Coastal Risks in Los Angeles County

Coastal communities are increasingly vulnerable to climate effects, such as sea level rise and coastal erosion. To address these and other changing coastal risks in Los Angeles County, NCCOS researchers extended their Integrated Vulnerability Assessment Framework to this densely populated and highly urbanized region, coupled with further spatial and economic ...

Assessing the Social and Cultural Importance of Subsistence Salmon in Alaska in the Context of the Natural Resource Damages Assessment Process

We are developing and validating a survey to measure the social and cultural importance of subsistence salmon harvest and use in Alaska. In the event of an oil spill or other hazard, NOAA’s Office of Response and Restoration can use our protocol to assess socio-cultural losses and develop restoration plans ...

Assessing the Threat of Hypoxia to Coral Reefs

We are examining the impact of low-oxygen (hypoxia) stress on coral reef ecosystems. Coral reefs are in decline, and human-assisted restoration is actively trying to reverse this trend. Our project will help improve the ability of coral reef managers and coral restoration practitioners to identify and understand the effects of ...

Assessment of Chemical Contaminants in Sediments and Biota from Cocos Lagoon, Guam

Funded by NOAA’s Coral Reef Conservation Program (CRCP), the goal of this project is to quantify the extent of chemical contamination in sediments and fish in Cocos Lagoon, Guam. Significant chemical contaminant issues have been identified in the area of Cocos Island, as a result of past land use activities ...

Assessment of Dredged Material Created Habitat in the South Atlantic Bight

Summary: We characterized the habitat formed by dredge material disposed in sites designated by the EPA offshore of Fernandina Beach, FL using SCUBA assessments, multibeam mapping, and hydroacoustic sampling of the fish community. The data was used to assess the value of the habitat informing future placement and disposal strategies ...

Assessment of Hurricane Impacts to Coral Reefs in Florida and Puerto Rico

In 2017, major hurricanes impacted coral reefs in both Florida and Puerto Rico. We quantified these impacts using diver-based surveys, and our information was used to guide targeted emergency stabilization of corals affected by the hurricanes. The National Fish and Wildlife Foundation in Florida and the Federal Emergency Management Agency ...
