Automated Sensor Provides Texas with Early Warning of Red Tide

Last week, an NCCOS-funded sensor submersed off 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 […]

Gulf of Mexico Alliance Produces Guide for Monitoring Harmful Algal Toxins

To improve the efficacy and consistency of toxin assessments and response, the Gulf of Mexico Alliance (GOMA) produced a guide for Gulf state managers on harmful algal bloom toxin monitoring protocols. GOMA collaborated with federal, state, academic, and NGO partners to advance Gulf ecosystem management through a coordinated, consensus-based approach. The National Centers for Coastal […]

Glider Begins Second Deployment to Monitor Threatening Florida Red Tide

A red tide of Karenia brevis in the Gulf of Mexico continues its slow advance toward Florida’s southwest coast. NOAA’s National Centers for Coastal Ocean Science (NCCOS) rapid response emergency funding is supporting a second deployment of underwater robotic gliders to track subsurface movement of the red tide. Since mid-July, a large red tide has lingered […]

International Conference Explores Emerging Contaminants in the Environment

Last month’s Fourth International EmCon Conference continued its tradition of advancing the science of emerging contaminants in the environment. NCCOS scientists presented research on how exposure of shrimp to antimicrobial compounds affects associated Vibrio bacterial density, and development of antibiotic resistance. The EmCon conference provided a forum to inform coastal managers about the occurrence, fate, […]
