New Pollution Scoring System Helps Identify Top Targets for Clean-Up

New published research by scientists at the National Centers for Coastal Science demonstrates an improved approach for calculating and comparing bioeffects levels in different places. Using a single numerical score, rather than the traditional system based on 3 distinct data sets (benthic community structure, sediment contamination, and sediment toxicity, known as the sediment quality triad) […]

Researchers Examine Night and Day Swings in Oxygen Depletion on Finfish and Oyster Habitat

NCCOS has awarded a team of researchers to predict the impact of hypoxia on commercially and ecologically important finfish and oysters living in the shallow waters of Chesapeake Bay. The project is a planned five-year grant estimated at nearly $1.6 million. The Smithsonian Institution will lead a team on this effort that includes the University of […]

New Research Aims to Unravel How Nutrients Drive Toxic “Brown Tides”

NOAA has awarded Massachusetts-based Woods Hole Oceanographic Institution $120,000 as part of an anticipated three-year, nearly $500,000 project, to determine how nitrogen and phosphorus promote brown tides on the East Coast. Funds were awarded through the interagency Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) program, represented at NOAA by the National Centers for Coastal […]

Invasive Sea Squirts Threaten Shellfish Aquaculture

National Centers for Coastal Ocean Science researchers and their collaborators found that ten invasive tunicate species are fouling shellfish aquaculture operations along much of the U.S. East Coast, causing decreased growth rates, increased mortality, and high maintenance costs.  The survey identified the locations of highest fouling, which will be used to develop a plan to […]

Toxic Free Radical Produced by Pfiesteria piscicida: A New Paradigm in Marine Toxins

Background First discovered in the late 1980s, Pfiesteria bloomed in 1997 in Chesapeake Bay tributaries in association with fish kills and human health problems, resulting in large economic losses due to lost seafood sales and tourism. That outbreak led to a large research effort to understand the causes and prevent or minimize the impacts of […]

Assessment Quantifies Extent of Sediment Contamination, Toxicity in Chesapeake Bay

The National Centers for Coastal Ocean Science (NCCOS) has released “Magnitude and Extent of Contaminated Sediment and Toxicity in Chesapeake Bay“, a report that provides chemical contaminant and benthic organism information useful for management planning efforts and understanding the Bay ecosystem. Sediment contaminants often pose ecological and human health risks through degraded habitats, loss of […]
