NOAA Seminar Series Features Patuxent River Shellfish Aquaculture and Eutrophication Research

A scientist from NCCOS’s Center for Coastal Monitoring and Assessment described a modeling study in Chesapeake Bay region’s Patuxent River Estuary at the NOAA NOS Science Seminar Series on June 3, 2015. The presentation, titled “Shellfish Aquaculture: A Strategy for Eutrophication Mitigation in the Patuxent River,” reported nitrogen removal estimates through cultivation and harvest of oysters […]

Getting the Word Out: Sharing the Benefits of Shellfish Aquaculture

Different aspects of shellfish aquaculture science were recently shared on three separate occasions with regional groups that varied from industry partners to regional growers to high school students. These presentations are part of an effort to communicate best practices of shellfish aquaculture to the public and stakeholders so that these methods will be employed in […]

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 […]

Oyster Gardening Improves Water Quality, Featured by National Geographic

The innovative “Maryland Grows Oysters” program, designed to use oyster restoration for improvement of water quality in Chesapeake Bay, was featured in a National Geographic video released on October 9. The project uses cages first produced by inmates at the Hagerstown Correctional Facility and then filled with baby oysters (or spat), which are attached to docks at volunteer study locations within the Chesapeake […]

NCCOS Completes Ecosystem Assessment of Chesapeake Bay Watersheds

NCCOS recently completed an assessment of three watersheds in the Chesapeake Bay region (Corsica, Magothy, and Rhode Rivers), exploring the linkages between dominant land-use type (agriculture, residential, and mixed-use, respectively) and aquatic ecosystem health. Habitat health was determined based on factors of water quality including dissolved oxygen, nitrogen, and phosphorous concentrations, and aquatic organism health […]

NCCOS Project Wins Publication Award

A paper supported by the National Centers for Coastal Ocean Science project “Multiple Stresses in Mid-Atlantic Shoreline Habitats”  won the 2014 American Water Resources Association (AWRA) Boggess Award for the best paper published in the Journal of the AWRA in the prior year. The paper, “Using Multiple Watershed Models to Predict Water, Nitrogen, and Phosphorus […]

Declining Oxygen Levels Threaten Oysters in Chesapeake Bay

NCCOS-sponsored research by the Smithsonian Institution Environmental Research Center (SERC) reveals low dissolved oxygen (hypoxia) hampers oysters’ ability to fight Dermo, a disease that has ravaged oysters throughout the Chesapeake Bay, resulting in up to two to three times more infected oysters than in waters with normal oxygen levels. Hypoxia is commonly studied on large geographic […]

NOAA, Partners Issue Dead Zone Predictions for Gulf of Mexico and Chesapeake Bay

Scientists are expecting an average, but still large, hypoxic or “dead zone” in the Gulf of Mexico this year, and a slightly above-average hypoxic zone in the Chesapeake Bay. NOAA-supported modeling is forecasting this year’s Gulf of Mexico hypoxic (very low oxygen) zone to cover an area ranging from 4,633 to 5,708 square miles (12,000 […]
