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 […]

Establishing Sustainable and Cooperative Dead Zone Monitoring in the Gulf of Mexico

Scientists, managers, and agency personnel from 26 stakeholder agencies and institutions met to establish a sustainable multi-partner hypoxia monitoring program in the northern Gulf of Mexico at the NCCOS sponsored 6th Annual NOAA/Northern Gulf Institute Hypoxia Research Coordination Workshop. The 2012 Gulf of Mexico Hypoxia Monitoring Implementation Plan and subsequent workshops provided a foundation to move […]

Study Shows Harmful Algal Bloom Species Has Distinct Bacterial Flora

A new study supported in part by the NCCOS Monitoring and Event Response for Harmful Algal Blooms (MERHAB) finds the harmful algal bloom (HAB)-forming diatom Pseudo-nitschia (PN) maintains a distinct bacterial community living on and near its exterior cell wall. The findings offer new insights into possibly using bacteria as indicators of HAB species composition, control […]

NOAA Funds Harmful Algal Bloom Forecast System Development in Pacific Northwest

NOAA’s National Centers for Coastal Ocean Science (NCCOS) are funding development of a harmful algal bloom (HAB) forecast in the Pacific Northwest to support management of shellfisheries, clamming beaches, and human health. The experimental monitoring and forecasting system will launch in 2017, with forecast bulletins predicting bloom location and concentration several days in advance. Annual […]

Southeast Alaska Tribes Trained in Minimizing Risk of Shellfish Toxins

NCCOS scientists instructed environmental personnel from the southeast Alaska tribes in toxic phytoplankton sampling and identification techniques during the Fourth Workshop of the Southeast Alaska Tribal Toxins (SEATT) Partnership in Sitka, Alaska. The NCCOS Phytoplankton Monitoring Network developed these techniques. Also at the workshop, NCCOS scientists provided technical and program development guidance to the Sitka Tribe […]
