Coastal Development Impacts Puerto Rico’s Mesophotic Coral Ecosystems

NCCOS-supported research recently published in Coral Reefs suggests coastal development negatively impacts mesophotic coral ecosystems, which were previously considered less likely to be affected by anthropogenic activities due to their greater depths. The project assessed the vulnerability of light-dependent mesophotic coral ecosystems (MCEs) off the south coast of Puerto Rico to anthropogenic impacts. Results showed that MCEs located […]

Climate Patterns Influence Amount of Fecal Bacteria in Maryland Shellfish Harvest Waters

NCCOS scientists and their partners have identified a link between inter-annual patterns of precipitation and air temperature and fecal coliform levels in shellfish harvest waters in Maryland’s portion of the Chesapeake Bay. Drawing on 34 years of monitoring data (1979–2013) from the Maryland Department of the Environment, the team found that fecal coliform tended to be […]

Sea Star Wasting Disease Discovered in Alaska

Researchers from NCCOS and the University of Alaska Fairbanks School of Fisheries and Ocean Sciences found evidence of sea star wasting disease in Alaska while surveying intertidal areas near NOAA’s Kasitsna Bay Laboratory. The team found the diseased sea stars during long-term monitoring surveys conducted under the Gulf Watch Alaska program at sites around Elephant […]

Low Oxygen Conditions Increase Parasite Infections in Oysters

A study funded in part by NCCOS has found that diel-cycling hypoxia—daily cycling of high to very low oxygen levels—in shallow coastal waters increases parasite infections in eastern oysters (Crassostrea virginica). The project team tested and confirmed that diel-cycling hypoxia increases eastern oyster susceptibility to Perkinsus marinus infection, most likely by reducing the oxygen carrying capacity […]

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 […]

NCCOS Scientist to Advise Shellfish Sanitation Experts on Harmful Algae Lab Methods

The National Centers for Coastal Ocean Science’s (NCCOS) Dr. Quay Dortch will join the Interstate Shellfish Sanitation Conference (ISSC) as an expert advisor. Dr. Dortch’s advice and expertise will contribute to one of the most technical and specialized areas of shellfish sanitation, that of laboratory methods for detecting and testing harmful algal toxins and their syndromes. […]

Scientists Recognized for Role in Assessing Dolphin Mortalities

Last month, scientists from NCCOS’s Center for Coastal Environmental Health and Biomolecular Research (CCEHBR) received an Outstanding Achievement Award from NOAA’s National Marine Fisheries Service for their efforts in assessing dolphin mortalities along the South Carolina coast during the 2013–2014 unusual mortality event of bottlenose dolphins. CCEHBR staff and their partners from Coastal Carolina University […]

New Assay Rapidly Detects Pathogens in Marine Mammals

A three-year project by NCCOS scientists has culminated in a reliable tool for rapid detection of pathogenic Brucella bacteria in clinical samples from marine mammals. Rapid detection of these pathogens in marine mammals has been difficult ever since Brucella infections were first recognized in marine mammals in the 1990s. Brucellosis, a Brucella-based reproductive disease, is […]
