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 […]

NOAA, Partners Predict Large Harmful Algal Bloom in Western Lake Erie this Summer

According to NOAA and its partners from several Ohio universities, western Lake Erie will have a large bloom of cyanobacteria, a toxic blue-green algae, in late summer. The predicted bloom is expected to be smaller than last year’s intense bloom and considerably less than the record-setting 2011 bloom. Bloom impacts will vary across the lake’s western basin, […]

Wave and Current Sensors Deployed to Enhance Reef Recovery in Puerto Rico

Researchers have deployed five oceanographic moorings on the coastal shelf off of Guayanilla, Puerto Rico, equipped with high-precision instrumentation to measure currents and waves. The data collected by the instruments will be used to fine tune models that are used to forecast coral reef recovery after large-scale disturbances, such as vessel groundings and hurricanes. Previous […]

Congress Reauthorizes National Harmful Algal Bloom and Hypoxia Legislation

On June 17, 2014, Congress passed a reauthorization of the Harmful Algal Bloom and Hypoxia Research and Control Act (HABHRCA)—legislation last reauthorized in 2004. HABHRCA is critical for protecting the public from these environmental events, as well as furthering NOAA’s goals to maintain healthy oceans and build resilient coastal communities and economies. In a roll call […]

High-tech Armada Links Toxic Algal Blooms and Nutrients from Sewage off Southern California

Last month, NCCOS-funded scientists deployed two Environmental Sample Processors, two research vessels, five autonomous underwater vehicles, and five drifters in the ocean around San Pedro Bay, off Southern California, seeking signs of harmful algal blooms (HABs). Not long after deployment, this high-tech armada detected a large phytoplankton bloom that included the diatom Pseudo-nitzschia and its […]

Origins of Harmful Alga Scourge in Pacific Northwest Confirmed

Researchers have identified the oceanographic causes and routes for the harmful alga Pseudo-nitzschia in offshore waters of the Pacific Northwest. The team’s validated model shows that toxic Pseudo-nitzschia cells arrive at the coast, not from a single source (as previously thought), but from two sources, one north and one south of Washington’s beaches. The northern source […]

Underwater Robots Detect Toxic Algae off Southern California

Two autonomous underwater robots deployed in San Pedro Bay off southern California have detected the diatom Pseudo-nitzschia and its potent neurotoxin domoic acid. This may signal the initiation of a harmful algal bloom along the coast that could impact a variety of wildlife and fishery resources. The robots, known as Environmental Sample Processors, are essentially underwater, molecular […]

Galveston Bay Closed to Oyster Harvesting After Scientists Detect Toxic Algal Bloom

The Texas Department of State Health Services is temporarily closing all of the Galveston Bay system to the harvesting of oysters, clams, and mussels because of elevated levels of an alga that can produce a toxin in some shellfish. NCCOS-funded scientists at Texas A&M University detected the harmful algal bloom and notified the state agency, […]
