Expanding Harmful Algal Bloom Monitoring in Western Lake Erie

The NCCOS Phytoplankton Monitoring Network, established to monitor phytoplankton and harmful algal blooms (HABs), is partnering with the U.S. Environmental Protection Agency to expand into the Western Basin of Lake Erie.  Monitoring stations were selected with input from NOAA’s Ecological Forecasting Services to provide strategic sites to support the NCCOS Lake Erie Experimental Forecast. Recently, the […]

State-of-the-Knowledge Report: Ecotoxicology in a Changing Global Climate

NCCOS scientist, Marie DeLorenzo, used results of toxicity testing at the NCCOS laboratory in Charleston, SC, along with a compilation of peer-reviewed literature studies to summarize the state-of-the-knowledge of the impacts of climate change on the ecotoxicology of chemical contaminants in estuarine organisms. Trends in effect of temperature and salinity on chemical contaminant toxicity were […]

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 […]

Persistent Organic Pollutants Unlikely Cause of Dolphin Health Issues after Deepwater Horizon

NCCOS scientists reported that persistent organic pollutants (POPs) were likely not a contributing factor to the poor health conditions and increased mortality observed in some populations of bottlenose dolphins following the Deepwater Horizon (DWH) oil spill.  This study, recently published in the journal Science of the Total Environment, analyzed 169 remote biopsy samples that were […]

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 […]

Sensor Provides Early Warning of Toxic Algal Bloom in Offshore Waters of Monterey Bay

NCCOS-developed domoic acid sensors on board two Environmental Sample Processors (ESPs) deployed in Monterey Bay, California have provided early warning of a toxic Pseudo-nitzschia algal bloom. Only a week into the deployment that began in early May, particulate domoic acid levels exceeded 30 micrograms per liter of seawater, which was consistent with the ESPs also detecting very high concentrations […]

NCCOS Methods Transferred to Algal Toxin Testing Laboratory in Oman

NCCOS researcher Tod Leighfield trained three scientists with Oman’s Ministry of Agriculture and Fisheries in standard sample preparation and toxin detection methods as part of an International Atomic Energy Agency–funded project to establish a harmful algal bloom testing laboratory in the Arabian Gulf region. The training included assistance with set up of the laboratory and instruction on […]

NCCOS Prepares Toxin Sensor for Gulf of Maine Red Tide Forecasting

An NCCOS technical expert completed critical calibrations of the paralytic shellfish poisoning (PSP) toxin sensor for an Environmental Sample Processor (ESP) platform stationed at the Woods Hole Oceanographic Institution’s Laboratory for Ocean Sensors and Observing Systems (LOSOS). Beginning in early May, this ESP will perform autonomous, near real-time monitoring of toxins associated with cells of the red […]
