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 […]

Puget Sound Stakeholders See Value in HAB Forecasts

At a June 26 meeting, NCCOS-funded ECOHAB project investigators concluded that climate change could increase the window of opportunity for blooms of the toxic dinoflagellate, Alexandrium catenella to occur. In light of this information, state officials expressed strong interest in seasonal HAB forecasts, while industry and local managers requested daily to weekly forecasts. Although future climate change will […]

New Online Community Created to Improve National HAB Response

NCCOS and the U.S. National Office for HABs established a new listserv to address diarrhetic shellfish poisoning. This emerging harmful algal bloom (HAB) issue has caused shellfish harvesting closures in Washington and Texas, human illness in Washington, and threatens other states. The online community of researchers; national, state, local, and tribal officials and public health […]
