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 Modeling Tool Detects and Forecasts Red Tide in the Gulf of Mexico

The week of July 21, a new modeling tool based on models funded by the NCCOS Ecology and Oceanography of Harmful Algal Bloom (ECOHAB) and Monitoring and Event Response for Harmful Algal Blooms (MERHAB) Programs predicted and detected a Red Tide harmful algal bloom (HAB) off the West Coast of Florida. The University of South […]

Enhanced Monitoring Saved Puget Sound Net Pen Salmon Threatened by Extreme Harmful Algal Bloom

In June, the straits, bays and islands of Puget Sound experienced some of the most extensive harmful algal blooms (HABs) in recent memory, including at least five potential toxin producers. Blooms of Heterosigma akashiwo, which causes massive fish kills, were widespread and threatened the salmon net pen mariculture industry. Enhanced HAB monitoring in the area led […]

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, […]

New Protocol Allows Scientists to Monitor Toxic Bottom-dwelling Algae at Low Cost

Using little more than a window screen to collect algae, NCCOS scientists have developed a simple, low-cost protocol for monitoring harmful, bottom-dwelling algae in diverse marine habitats around the world. The window screens mimic natural surfaces that harbor toxic algae and allow direct comparisons of algae abundance from different locations. In a series of field […]

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 […]

Advocate for Harmful Algal Bloom Research Honored

NCCOS’s Dr. Frances Quay Dortch has been honored for her dedication to and advocacy for research on toxic algae and the impacts of harmful algal blooms (HABs). A special issue of the scientific journal Deep Sea Research is dedicated to her as “a scientist and program manager who has worked tirelessly in support of U.S. HAB research […]

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 […]
