Supporting Virginia Sea Grant Aquaculture Work

At the Virginia Sea Grant’s Annual Symposium held in Richmond, Va. on Jan. 23, researchers from NCCOS, the Virginia Institute of Marine Science, and private industry developed strategies to find and forecast harmful algal blooms to support Virginia’s growing shellfish aquaculture industry. Participants representing research, industry, and government also discussed strategies that would allow Virginia […]

Decaying Harmful Algal Blooms Still Dangerous: New Model Predicts Toxicity to Humans

Declining (terminating) harmful algal blooms continue to pose health hazards. When some harmful algal blooms die and disappear, their toxicity continues to affect the air above the bloom-infested waters. Some dinoflagellates produce toxins—such as the brevetoxins from the Florida red tide (Karenia brevis)—that are readily aerosolized when nearshore blooms die and release their toxins into […]

NCCOS Research in Today’s Rapidly Changing Global Environment

Two national science conferences recently highlighted NCCOS research: The theme at the 7th Symposium on Harmful Algae in the United States (Oct. 27–31, 2013; Sarasota, FL) was harmful algal blooms (HABs) in a changing world, especially a more acidic one. NCCOS HAB scientists and sponsored researchers  organized, advised,  chaired sessions, and presented some 13 oral […]

New Research in the Gulf of Maine Improves Red Tide Forecasting

Scientists from the National Centers for Coastal Ocean Science recently teamed with sponsored partners to collect sediment samples in the Gulf of Maine needed to find cysts of the harmful algae Alexandrium fundyense. The data collection took place on Nov. 6–11 aboard NOAA’s research ship Okeanos Explorer—the first time a NOAA ship has been used […]

NCCOS Calibrates Harmful Algal Bloom Toxin Sensors in California

An NCCOS scientist visited the Monterey Bay Aquarium Research Institute on Nov. 6–13 to perform critical calibration of NCCOS-developed domoic acid sensors on two robotic Environmental Sample Processors (ESPs). Results of these calibrations and the analysis of controlled test samples will allow researchers to accurately quantify harmful algal bloom toxin data generated during two ESP […]

High Tech Sensors Used to Investigate Harmful Algal Bloom ‘Hot Spots’ in California

NCCOS scientists and their partners from the Monterey Bay Aquarium Research Institute (MBARI) are investigating the causes of Pseudo-nitzschia blooms and toxicity in Monterey Bay, Calif. from Sept. 5 to Oct. 10. Under the right conditions, some Pseudo-nitzschia produce domoic acid, a potent neurotoxin. Domoic acid accumulates in fish and shellfish, has caused bird and […]

California Red Tides and Other Algal Blooms Explained

The importance of algal blooms to the ecology of the ocean, including harmful red tides, is highlighted in a new “podcast” from the California nonprofit “Thank You Ocean Campaign.”  The podcast, entitled “Should We Fear Red tides?,” features Dr. Raphael Kudela from the University of California Santa Cruz. Dr. Kudela explains why harmful algal blooms […]

NCCOS Scientists Collaborate with GLERL and University Researchers for Improved HAB Forecasting.

From June 4 – 6, Researchers from the National Centers for Coastal Ocean Science (NCCOS) met with Great Lakes Environmental Research Lab (GLERL) and regional university scientists from Heidelberg University, University of Toledo, Ohio State University, and the University of Michigan at the International Great Lakes Conference in Lafayette, IN.  Participants developed new collaborative efforts […]
