New Guidance for Managing HAB Impacts on California Fisheries

A newly released report from the California Ocean Science Trust highlights efforts to learn from the 2015 massive bloom of the toxin-producing marine diatom Pseudo-nitzschia that formed off the U.S. West Coast. The harmful algal bloom (HAB) impacted key fisheries, such as Dungeness crabs and razor clams, and marine mammals from California to Alaska. NOAA […]

Stakeholders Meet to Develop Harmful Algal Bloom Action Plan for Alaska

Alaska Sea Grant and the Alaska Ocean Observing System recently cosponsored a two-day workshop to develop an action plan for harmful algal bloom (HAB) monitoring, event response, outreach, and research in Alaska. NCCOS staff opened the workshop by providing a national perspective on HABs that set the stage for discussions of existing activities and identified […]

NCCOS Provides HAB Technology Guidance to African Countries Under United Nations Program

NCCOS recently led a two-week training course on harmful algal bloom (HAB) sampling and toxin analysis at the Kenya Marine Fisheries and Research Institute in Mombasa, Kenya.  This regional training course was organized for countries throughout Africa with support of a United Nations International Atomic Energy Agency (IAEA)-funded project to establish toxin sampling and analysis capabilities in African […]

Harmful Algal Cyst Sampling Lays Groundwork for 2017 Gulf of Maine Forecast

Scientists from NOAA and Woods Hole Oceanographic Institution (WHOI) recently completed their annual harmful algal cyst sampling in the Gulf of Maine, a critical step for forecasting next year’s harmful algal blooms (HABs) of the toxic Alexandrium fundyense, commonly known as New England red tide. A. fundyense has both a vegetative stage, where cells grow and float in surface […]

Predicting the Risks of Harmful Algal Blooms for Coastal California

In California, domoic acid-producing harmful algal blooms (HABs) of the diatom Pseudo-nitzschia increasingly threaten bivalve and crab harvesters, aquaculture, and coastal ecosystems. Using a blend of models and satellite ocean color imagery, NCCOS supported the early development of the California Harmful Algae Risk Mapping (C-HARM) system that predicted the spatial likelihood of Pseudo-nitzchia blooms and levels of […]

Tiny yet Toxic: Dinoflagellate Karlodinium veneficum

Relatively unknown and taxonomically confusing until the last few decades, the tiny but toxic dinoflagellate, Karlodinium veneficum, can produce dense blooms and fish-killing toxins. K. veneficum is a small chlorophyll-containing dinoflagellate that produces a suite of potent toxic compounds known as karlotoxins which kill fish as well as other organisms. K. veneficum has a mixed nutritional mode […]

NCCOS Helps New England Respond to Unprecedented Harmful Algal Bloom

For the first time in New England’s coastal waters, shellfish have exceeded the regulatory limit for domoic acid—a potent neurotoxin produced by the diatom Pseudo-nitzschia. Domoic acid accumulates in shellfish that feed on Pseudo-nitzschia, and can lead to amnesic shellfish poisoning in people who consume tainted shellfish. The NCCOS Harmful Algal Bloom Event Response Program […]

NOAA Awards $10.44 million for Coastal Science: Sea Level Rise, Hypoxia and Harmful Algal Blooms

October 25, 2016 - NOAA’s National Centers for Coastal Ocean Science will award $10.44 million over the next five years for 10 projects to address sea level rise, hypoxia and harmful algal blooms (HABs). Among the projects the 10 awards will support are: coastal lowland habitat research in California; understanding and mitigating sea level rise and […]
