Tenacity of Brown Tides Linked to Genetic Flexibility

The genetic flexibility of Aureococcus anophagefferens, the harmful algae responsible for “brown tides” off Long Island, allows it to thrive in conditions other algae cannot tolerate. NCCOS-sponsored scientists assessed this algae’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 […]

Incorporating Shoreline Fluctuations into Tidal Models Improves Sea Level Predictions

Research sponsored by the National Centers for Coastal Ocean Science demonstrates the importance of incorporating dynamic shoreline changes into models over time to forecast sea level change impacts. Projected sea level change impacts are often depicted by assuming coastlines migrate unaltered over time with the rising or falling sea level. While valid for hard, rocky shorelines, […]

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 […]

New Molecular Tool Screens Bait Fish for Invasive Species Risk

Sixty-nine of 180 aquatic invasive species (AIS) in the Great Lakes region are fish, many of which pose threats to native species and ecosystem functioning. One potential pathway for AIS introductions is the commercial bait trade; anglers commonly release unused bait fish back into lakes and streams, despite current regulations and management in the Great Lakes region. Previous […]

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 […]

NCCOS Project Wins Publication Award

A paper supported by the National Centers for Coastal Ocean Science project “Multiple Stresses in Mid-Atlantic Shoreline Habitats”  won the 2014 American Water Resources Association (AWRA) Boggess Award for the best paper published in the Journal of the AWRA in the prior year. The paper, “Using Multiple Watershed Models to Predict Water, Nitrogen, and Phosphorus […]
