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 […]

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 […]
