Diarrhetic shellfish poisoning (DSP) has emerged as a significant and expanding seafood safety threat in coastal regions across the United States. The harmful algal species Dinophysis produces toxins known to ...

National Estuarine Eutrophication Assessment: Upda...

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 used the Assessment of ...

Outdoor Recreation in Coastal Virginia

Oyster Aquaculture Related Ecosystem Services in t...

Eutrophication—the overabundance of nutrients in a body of water—threatens the normal function and benefits provided by coastal ecosystems. Attempts to reverse eutrophication have focused on reducing land-based sources of nutrients ...

Oyster Marking Methodology Study

We are developing methods to imprint oysters with a non-toxic fluorochrome dye to give scientists, aquaculturists, health officials, and enforcement agencies the ability to positively re-identify marked oysters. Why We ...

Predicting Impacts of Climate Change on Success of...

We are investigating how rising atmospheric temperature and changing precipitation patterns will affect coastal hypoxia (low dissolved oxygen) in Chesapeake Bay. Hypoxia in the bay, caused by an excessive influx ...

The U.S. Army Corps of Engineers (USACE) Engineering With Nature® Initiative held an international virtual book launch ceremony on April 7, 2021 to celebrate the release of Engineering With Nature: ...

Climate-induced Wind Upwelling Could Further Acidi...

A NCCOS and NOAA Ocean Acidification Program sponsored study investigated how physical properties such as winds, tides, and currents impact estuarine acidification and carbonate chemistry in the Chesapeake Bay estuary, ...

Reviews of Our Current Understanding of Harmful Di...

In a recently released book on dinoflagellates, three chapters update knowledge of and changing views for the red tide alga Karenia brevis and the estuarine Pfiesteria-like dinoflagellates Pfiesteria piscicida and ...

Shoreline Armoring Promotes Spread of Invasive Ree...

A stand of Phragmites australis. Credit USDA. An NCCOS-funded study found that shoreline armoring in Chesapeake Bay promotes the spread of the invasive common reed (Phragmites australis) by stimulating greater ...

Data & Publications

Habitat Affects Survival of Translocated Bay Scallops, Argopecten irradians concentricus (Say 1822), in Lower Chesapeake Bay

Bay scallop (Argopecten irradians) populations existed in Chesapeake Bay until 1933, when they declined dramatically due to a loss of seagrass habitat. Since then, there have been no documented populations within the Bay. However, some anecdotal observations of live bay ...

Harmful Algal Bloom Forecasting Branch Ocean Color Satellite Imagery Processing Guidelines

The Harmful Algal Bloom - Forecasting Branch (HAB-FB) is a research group within the National Oceanic and Atmospheric Administration (NOAA), National Centers for Coastal Ocean Science (NCCOS) tasked with forecasting and monitoring HABs. One of the more effective ways to ...

Histological techniques for marine bivalve mollusks and crustaceans

During the mid-1950s, massive and widespread oyster mortalities, particularly in the Delaware and Chesapeake Bay areas, served as a stimulus to establish a federal oyster mortality study program. Consequently, Congress appropriated funds to the then Bureau of Commercial Fisheries (BCF) ...

Human Use Pharmaceuticals in the Estuarine Environments: A Survey in the Chesapeake and Biscayne Bays

The goal of this pilot project was to assess the presence of a number of commonly prescribed human use pharmaceuticals in three coastal areas of the U.S. Water samples were collected in conjunction with three NOAA monitoring/research projects to assess ...

Hypoxia-induced shifts in nitrogen and phosphorus cycling in Chesapeake Bay

We investigated interactions between hypoxia and nutrient cycling in Chesapeake Bay using quantitative analysis of long?term monitoring data covering the periods 1965?1980 and 1985?2007. The data included vertical water column profiles of temperature, salinity, NH+4, PO3?4, and O2, as well ...

Identification of a vacuolar proton channel that triggers the bioluminescent flash in dinoflagellates

In 1972, J. Woodland Hastings and colleagues predicted the existence of a proton selective channel (HV1) that opens in response to depolarizing voltage across the vacuole membrane of bioluminescent dinoflagellates and conducts protons into specialized luminescence compartments (scintillons), thereby causing ...

Identifying priorities for adaptation planning: an integrated vulnerability assessment for the Town of Oxford and Talbot County, Maryland

The ecology of the Chesapeake Bay and its watershed is deeply intertwined in the history, culture, and economy of the communities in this region, and provides people with valuable ecosystem services. Due to the connectivity between communities and the environment, ...

Impact of Armored Shorelines on Shore-Zone Fish Density in a Mid-Atlantic, USA, Estuary: Modulation by Hypoxia and Temperature

Anthropogenic modifications of estuarine environments, including shoreline hardening and corresponding alteration of water quality, are accelerating worldwide as human population increases in coastal regions. Estuarine fish species inhabiting temperate ecosystems are adapted to extreme variations in environmental conditions including water ...

In Situ Effects of Shoreline Type and Watershed Land Use on Submerged Aquatic Vegetation Habitat Quality in the Chesapeake and Mid-Atlantic Coastal Bays

Submerged aquatic vegetation (SAV) is an ecologically and economically valuable component of coastal estuaries that acts as an early indicator of both degrading and improving water quality. This study aimed to determine if shoreline hardening, which is associated with increased ...

Integrating Regional Management Needs into a Mid-Atlantic Shorelines Research Projects

We provide an example of how one estuarine research project engaged regional managers to help guide the research towards the needs of managers and policymakers dealing with shoreline management in the Mid-Atlantic region of the USA. Elements of the approach ...
