Hypoxia Task Force Makes Progress to Reduce Runoff Fueling Gulf of Mexico Dead Zone

The Mississippi River Gulf of Mexico Watershed Nutrient Task Force (“Hypoxia Task Force”) works to reduce and control hypoxia, or the dead zone, in the Gulf of Mexico. At the Fall Public Meeting in Alton, Illinois, the Task Force reported recent progress in dead zone reduction. New measures and actions were passed to control  nutrient runoff which […]

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 […]

NCCOS helps Pennsylvania Prepare for Lake Erie Blooms

When Pennsylvania Governor Tom Corbett learned of the large toxic cyanobacteria (blue-green algae) bloom that disrupted the drinking water supply for hundreds of thousands of Ohio’s citizens, he expressed confidence his state was proactively planning to mitigate any potential human health impacts from toxic cyanobacteria blooms. This confidence grew from the state Department of Environmental Protection […]

How Climate Change Could Impact Harmful Algal Blooms

Harmful algal blooms (HABs) are projected to increase as sea surface temperatures rise and ocean acidification continues according to Dr. Alan Lewitus, of NOAA’s National Centers for Coastal Ocean Science. His findings were shared during a symposium at George Mason University in October which covered such topics as climate change and extreme weather effects on […]

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 […]

NOAA Supports Reduction in Gulf of Mexico Nutrient Loading

From August 12 – 14, seven of the U.S. Fish and Wildlife-led Landscape Conservation Cooperatives (LCCs) convened a workshop in Memphis, Tennessee to improve the allocation of wildlife management actions throughout the Mississippi River Basin in a way that reduces nutrient loading and hypoxia in the Gulf of Mexico, while balancing agricultural interests and supporting terrestrial […]

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 […]
