State and Federal Agencies Meet to Improve HAB Surveillance

NOAA and the Centers for Disease Control (CDC) recently co-sponsored a workshop on harmful algal blooms (HABs) to discuss future monitoring of HAB-related illnesses and outbreaks and to discuss with state representatives how NOAA’s remote sensing capabilities can support HAB surveillance. Attendees provided updates on HAB activities in each state and discussed the CDC’s National […]

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 […]

Eating USVI Invasive Lionfish Could Lead to Ciguatera Fish Poisoning

A new report by NCCOS-sponsored researchers shows that consumption of lionfish from the U.S. Virgin Islands (USVI) could lead to ciguatera fish poisoning. The research team analyzed ciguatera toxin levels in lionfish collected from waters surrounding USVI and found that about 40 percent of USVI lionfish have a measurable level of ciguatera toxin. The team […]

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 […]

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 […]

Texas Alerted to Toxic Pseudo-nitzschia Bloom in Galveston Bay

Volunteers with NOAA’s Phytoplankton Monitoring Network have reported a bloom of the diatom, Pseudo-nitzschia in Galveston Bay, Texas, and NOAA’s Analytical Response Team has confirmed that the bloom is producing domoic acid, a neurotoxin that can cause amnesiac shellfish poisoning. State managers of the Texas Parks and Wildlife Department and Texas Department of State Health […]

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, […]
