High-tech Armada Links Toxic Algal Blooms and Nutrients from Sewage off Southern California

Last month, NCCOS-funded scientists deployed two Environmental Sample Processors, two research vessels, five autonomous underwater vehicles, and five drifters in the ocean around San Pedro Bay, off Southern California, seeking signs of harmful algal blooms (HABs). Not long after deployment, this high-tech armada detected a large phytoplankton bloom that included the diatom Pseudo-nitzschia and its […]

Gulf of Maine Red Tide Forecast Suggests Modest Bloom: Robotic Sensors Deployed to Confirm and Improve Future Predictions

A team of NOAA and academic researchers led by the Woods Hole Oceanographic Institution (WHOI) has issued a seasonal red tide forecast for the Gulf of Maine as part of a pilot program that expands NOAA harmful algal bloom (HAB) forecasting to this region. The forecast suggests a modest bloom for the upcoming 2014 season. […]

Underwater Robots Detect Toxic Algae off Southern California

Two autonomous underwater robots deployed in San Pedro Bay off southern California have detected the diatom Pseudo-nitzschia and its potent neurotoxin domoic acid. This may signal the initiation of a harmful algal bloom along the coast that could impact a variety of wildlife and fishery resources. The robots, known as Environmental Sample Processors, are essentially underwater, molecular […]

New Pathogen and HAB Detection Device Designed with Volunteers in Mind

NCCOS-funded researchers at the University of Maine have developed a new, hand-held device for pathogen detection. The portable, easy-to-use, and inexpensive design of this sensor meets key use needs of volunteer and government public health, water, and shellfish monitoring personnel. Researchers plan to give these instruments to Maine Department of Marine Resources (DMR) harmful algal […]

Galveston Bay Closed to Oyster Harvesting After Scientists Detect Toxic Algal Bloom

The Texas Department of State Health Services is temporarily closing all of the Galveston Bay system to the harvesting of oysters, clams, and mussels because of elevated levels of an alga that can produce a toxin in some shellfish. NCCOS-funded scientists at Texas A&M University detected the harmful algal bloom and notified the state agency, […]

Identifying Origin and Mechanism of Texas Red Tide

A study funded by the National Centers for Coastal Ocean Science has tentatively identified the source and control mechanism of red tides (Karenia brevis) along the Texas coast. The research, led by Texas A&M University, incorporates a suite of linked models (e.g., biological–physical), combined with data from drifting sensors, satellites, and an automated underwater microscope […]

NCCOS-developed Method for Toxins Detection Approved for Regulatory Testing of Shellfish in the U.S

Earlier this year, the Interstate Shellfish Sanitation Conference (ISSC) approved a new assay developed by the National Centers for Coastal Ocean Science (NCCOS) as an official method for identifying toxicity that could result in paralytic shellfish poisoning. This approval is the culmination of more than a decade of effort to find an alternative to live animal […]

NCCOS Research Featured in EPA Webinar Series on Inland Harmful Algal Blooms

On Jan. 14, NCCOS researchers Steve Morton and Rick Stumpf were featured speakers at an Environmental Protection Agency (EPA) webinar focused on inland harmful algal blooms. The event was part of an EPA webinar series intended to build awareness about the effects of nutrient pollution and harmful algal blooms on the environment. Dr. Morton provided […]
