Improving Paralytic Shellfish Poisoning Response in Alaska

Harmful algal blooms, particularly those that cause paralytic shellfish poisoning, pose a threat to human health, food security, and the economy of local communities in Alaska. There is a need for greater understanding of these blooms by community members and for the development of an effective and integrated monitoring system. To meet these needs, NCCOS […]

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, […]

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 […]

Working with State to Document First Occurrence of Harmful Karenia mikimotoi Algae in Alaskan Waters

Starting in late Sept. 2013, a bloom of the phytoplankton Karenia mikimotoi began, progressed, and ultimately covered most of Kachemak Bay, Alaska. The bloom caused the water to turn brown and foam at the surface for several weeks, causing concern in local communities. In response, the Kachemak Bay National Estuarine Research Reserve and the NCCOS […]

Ocean Acidification Promotes Disruptive and Harmful Algal Blooms on Our Coasts

The general decline in ocean pH (i.e., more acidic conditions) from the increasing concentrations of carbon dioxide (CO2) is well documented. Also well documented are increased nutrients entering coastal waters often promoting excessive and ecosystem disruptive algae blooms, including harmful algal blooms. The decay of these coastal blooms promotes bacterial respiration resulting in increased CO2, […]

NCCOS Continues to Help Pennsylvania Respond to Lake Erie Harmful Algal Bloom

Following the first reported cyanohab bloom in Presque Isle State Park in July 2013, the NCCOS Harmful Algal Bloom (HAB) Rapid Response Team supported the Pennsylvania Department of Environmental Protection (PADEP) as they mobilized to address public concerns about toxins, recreational restrictions, and health advisories. This aid helped keep swimmers in the popular park safe, […]

NCCOS Aids Pennsylvania Response to First CyanoHAB in Presque Isle Bay, Lake Erie

The NCCOS Harmful Algal Bloom Event Response Program is assisting the Pennsylvania Department of Environmental Protection (PA DEP) respond to and document the first cyanobacteria harmful algal bloom (cyanoHAB) in Presque Isle Bay, along the south shore of Lake Erie. Researchers sampled the small scale bloom near Presque Isle State Park in late July, and […]

NCCOS Responds to Harmful Algal Bloom Event Threatening Florida’s Indian River Lagoon

The NCCOS Harmful Algal Bloom Event Response Program approved a request supporting rapid response to a harmful algal bloom (HAB) in the Indian River Lagoon system of East Central Florida. Dr. Chris Gobler from Stonybrook University will work with the St. Johns River Water Management District to map the extent of the 2013 Brown Tide […]
