NCCOS Aids West Coast Partners Responding to Extensive Harmful Algal Bloom

The National Centers for Coastal Ocean Science (NCCOS) is providing $88,000 in emergency funds to aid Washington State to respond to an unprecedented West Coast harmful algal bloom (HAB) event. The funding supports collection and analysis of samples for the toxic algal bloom species Pseudo-nitzschia and domoic acid – the neurotoxin it produces – from beaches and offshore of […]

NCCOS Trains Washington State Scientists in Improved Seafloor Mapping Methods

Scientists within NCCOS’ Biogeography Branch develop extensive seafloor maps and depict benthic habitats that better inform policy makers and resource management decisions. But NCCOS also aims to provide guidance for coastal states in conducting their own mapping, data collection and analysis in the future. Increasing state and federal scientific collaboration also supports regional marine spatial […]

NCCOS and NMFS Partner to Survey “Unprecedented” West Coast Toxic Algal Bloom

NOAA Fisheries announced it has mobilized extra scientists to join a fisheries survey aboard the NOAA Ship Bell M. Shimada charting an extensive harmful algal bloom (HAB) that spans much of the West Coast. An NCCOS sponsored Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) project in southern and central California comparing coastal HAB ‘hot spots’ analyzes water samples […]

Toxic Pseudo-nitzschia Bloom Reported in Alaska’s Kachemak Bay

Volunteers with the NOAA’s Phytoplankton Monitoring Network reported a bloom of the diatom, Pseudo-nitzschia occurring within NOAA’s National Estuarine Research Reserve System at Kachemak Bay, AK.  NOAA’s Analytical Response Team identified the bloom as Pseudo-nitzchia australis using scanning electron microscopy and confirmed the bloom produced the neurotoxin domoic acid, after which, state managers of the […]

Harmful Algal Cyst Mapping in Washington Shows 10-fold Increase since 2013

An unprecedented bloom of the harmful alga Alexandrium occurred during Fall 2014 in Quilcene Bay, Hood Canal, Puget Sound, WA; the outbreak contaminated shellfish with potent biotoxins that can cause paralytic shellfish poisoning. The area of the bloom was historically biotoxin free, but at the peak of the event, the Washington State Department of Health detected toxin […]

Puget Sound Harmful Algal Blooms Linked to Seasonal Patterns and Survival Probability

In order to predict blooms and prevent undue economic loss of commercial shellfish in Puget Sound, NCCOS has sponsored research investigating the seasonal patterns and mechanisms of bloom formation of Alexandrium, a dinoflagellate that contaminates shellfish and causes paralytic shellfish poisoning (PSP) in humans. The study shows Alexandrium survives and spreads in Puget Sound in response to […]

NCCOS, Partners Improve Aquaculture Siting and Production in Puget Sound

NCCOS and partners are using computer modeling to determine the carrying capacity for shellfish aquaculture—and the related potential for nutrient removal—in South Puget Sound. The team’s methodologies and guidelines will be used to inform marine spatial planning activities locally and throughout the U.S., promoting sustainable shellfish aquaculture and providing a framework for addressing issues that commonly lead […]

The Craib Corer: Predicting Harmful Algal Blooms by Sampling the Seafloor

Forecasting harmful algal blooms is a complex endeavor involving a wide range of oceanographic disciplines. NCCOS scientists and sponsored researchers count the number of harmful algal bloom (HAB) resting stages or cysts that lie on the bottom of the ocean as one method to estimate the future occurrence of HABs. Scientists use a suite of […]
