Gliders Map Large Red Tide Bloom in Gulf of Mexico for Rapid Response

NCCOS is supporting the rapid deployment of self-propelled underwater robotic gliders to map an emerging red tide bloom in the Gulf of Mexico. The bloom of Karenia brevis, Florida Red Tide, was detected by an NCCOS-sponsored new modeling tool on July 23 and the Florida Fish and Wildlife Commission (FWC) promptly issued a public red tide notice alerting the public of […]

New Online Community Created to Improve National HAB Response

NCCOS and the U.S. National Office for HABs established a new listserv to address diarrhetic shellfish poisoning. This emerging harmful algal bloom (HAB) issue has caused shellfish harvesting closures in Washington and Texas, human illness in Washington, and threatens other states. The online community of researchers; national, state, local, and tribal officials and public health […]

Congress Reauthorizes National Harmful Algal Bloom and Hypoxia Legislation

On June 17, 2014, Congress passed a reauthorization of the Harmful Algal Bloom and Hypoxia Research and Control Act (HABHRCA)—legislation last reauthorized in 2004. HABHRCA is critical for protecting the public from these environmental events, as well as furthering NOAA’s goals to maintain healthy oceans and build resilient coastal communities and economies. In a roll call […]

Toxins Detection Workshop Promotes International Trade of Shellfish

NCCOS scientist Tina Mikulski recently led a workshop in Muscat, Oman, on the detection of paralytic shellfish toxins—which can accumulate in shellfish, causing human illness and death. Shellfish must be screened for these toxins (produced by harmful algae in the genus Alexandrium) prior to sale and consumption. The workshop was designed through a formal agreement between […]

NOAA Teams with NIST to Transfer HAB Detection Methods to Portugal’s Marine Animal Rehabilitation Centre

NOAA’s harmful algal bloom Analytical Response Team has teamed with Hollings Marine Lab partner, the National Institute of Standards and Technology (NIST), to provide training for a NIST International Fellow on algal toxin detection in marine wildlife. Dr. Rute Costa of the Marine Animal Rehabilitation Centre in Figueira da Foz, Portugal, is nearing completion of this […]

Sentinel Site Alerts California Public to Toxic Shellfish

Routine sampling of marine mussels from a University of California sentinel site at the Santa Cruz Wharf prompted the California Department of Public Health (CDPH) to issue a health advisory warning for domoic acid poisoning due to high levels of the toxin in shellfish samples. The April 4, 2014 advisory warned consumers not to eat recreationally […]

Marine Life in Gulf of Mexico Face Multiple Challenges

By Maggie Broadwater, Guest Blogger from NOAA’s Harmful Algal Bloom Analytical Response Team. Animals living in coastal waters can face a number of environmental stressors—both from nature and from humans—which, in turn, may have compounding effects. This may be the case for marine life in the Gulf of Mexico which experiences both oil spills and the […]

Harmful Algal Bloom Intensity May be Tied to Ocean Carbon Dioxide Levels

Recent findings show that increases in oceanic carbon dioxidefrom the burning of fossil fuels over the last 200 years may have increased the intensity and toxicity of Karenia brevis blooms. Researchers from the National Centers for Coastal Ocean Science (NCCOS) report that this effect is projected to increase substantially by the turn of the century with […]
