State-of-the-Knowledge Report: Ecotoxicology in a Changing Global Climate

NCCOS scientist, Marie DeLorenzo, used results of toxicity testing at the NCCOS laboratory in Charleston, SC, along with a compilation of peer-reviewed literature studies to summarize the state-of-the-knowledge of the impacts of climate change on the ecotoxicology of chemical contaminants in estuarine organisms. Trends in effect of temperature and salinity on chemical contaminant toxicity were […]

NCCOS’s Mussel Watch Program to Assess Chesapeake Bay for New and Emerging Water Pollutants

Scientists from NCCOS are partnering with the Maryland Department of Natural Resource (MD-DNR) to launch a monitoring project in the Chesapeake Bay designed to survey the magnitude and distribution of contaminants of emerging concern (CECs). CECs, such as current-use pesticides, pharmaceuticals, personal care products, and other chemicals associated with human activities, can enter the environment […]

NCCOS Scientists Assess Chemical Contaminants in Cocos Lagoon

NCCOS scientists recently traveled to Guam for a project funded by NOAA’s Coral Reef Conservation Program (CRCP), to help quantify chemical contamination in Cocos Lagoon, located at the southern tip of the island.  Working with local partners, including the Guam Environmental Protection Agency, Guam Department of Agriculture, the University of Guam, NOAA NMFS and CRCP, […]

Studying Contaminants in Cocos Lagoon, Guam: Blog Post #3

For sediment sampling in Cocos Lagoon, we used what is known as a “stratified–random design.” Basically, a series of strata (layers) were developed in consultation with local partners, and then random sampling points were scattered in each stratum. At these points, samples of sediment could be collected. By using this design, any point within a […]

Measuring Parasites and Disease in U.S. Oysters and Mussels

NOAA today released its first-ever long term report of the national distribution of parasites and disease in mussels and oysters, concluding that there was no general threat to oyster and mussel population in the nation’s coastal waters at the time of the study, despite some locations along the Gulf of Mexico and West Coast with […]
