Additional Toxin Data Helped Ohio Deliver Safe Drinking Water After August Cyanobacteria Bloom

Persistent concerns about toxins in Toledo, Ohio’s drinking water following August’s large, cyanobacteria bloom in Lake Erie prompted a follow-up investigation supported by NCCOS. At the time, the bloom led the City of Toledo to issue a two-day, drinking water ban for 400,000 people in Toledo and surrounding areas after drinking water samples showed high […]

Phytoplankton Monitoring Network Volunteers in Georgia Trained in Marine Debris Reporting

The NCCOS Phytoplankton Monitoring Network (PMN) program recently trained volunteers from Georgia in harmful algal bloom and marine debris monitoring. Volunteers from Gray’s Reef National Marine Sanctuary, Burton 4-H, and the University of Georgia’s Marine Extension Service received instruction on target phytoplankton species for change detection, as well as how to identify microplastics in phytoplankton […]

NCCOS Embarks on Harmful Algal Cyst Sampling Cruise

Scientists from NCCOS and Woods Hole Oceanographic Institution embark today aboard NOAA’s research ship, the Okeanos Explorer, on a nine-day sediment sampling mission in the Gulf of Maine. Researchers will examine sediment cores for the presence of cysts of the harmful alga Alexandrium fundyense to improve forecasting of harmful algal bloom (HAB) events along the […]

Automated Sensor Provides Texas with Early Warning of Red Tide

Last week, an NCCOS-funded sensor installed on a Port Aransas pier alerted Texas agencies to rising concentrations of Karenia brevis, the marine dinoflagellate that causes red tides. The Texas Parks and Wildlife Department, the Texas Department of State Health Services, and other interested managers received a two-week early warning that a red tide bloom was […]

NCCOS Partners with White House to Improve Detection of Excess Nutrients in Aquatic Environments

Earlier this month, NOAA’s National Centers for Coastal Ocean Science and other partners joined the White House Office of Science and Technology Policy in Washington, DC for a workshop to accelerate the development and adoption of nutrient sensors. Excessive amounts of nutrients (mainly nitrogen and phosphorus) entering lakes, rivers, streams, and coastal waters are causing […]

Tenacity of Brown Tides Linked to Genetic Flexibility

The genetic flexibility of Aureococcus anophagefferens, the harmful alga responsible for “brown tides” off Long Island, allows it to thrive in conditions other algae cannot tolerate. NCCOS-sponsored scientists assessed this alga’s response to environmental stressors, such as low nutrients and low light, by looking at pieces of its RNA, which tell Aureococcus which proteins to […]

What Powers Florida Red Tides?

The results of a long-term research project, sponsored by NOAA’s National Centers for Coastal Ocean Science, focused on the Gulf of Mexico red tide are featured in a special issue of the scientific journal Harmful Algae. History records blooms of the harmful Florida red tide (caused by the microalgal dinoflagellate Karenia brevis) occurring centuries before Florida’s mid-late […]

Algal Toxins Pose Health Risk to Dogs

Harmful algal bloom (HAB) toxins, including microcystins, pose health threats and even death for dogs and other pets exposed to the contaminated water, explains a new educational brochure from the New York Sea Grant Program. The brochure, a product of a National Centers for Coastal Ocean Science sponsored research project in the Great Lakes, describes freshwater HABs and their […]
