Spring Flood Outlook Has Implications for Gulf of Mexico and Chesapeake Bay Hypoxia

The NOAA 2014 U.S. Spring Flood Risk Assessment provides an important first look at some of the factors that influence summer hypoxia (low dissolved oxygen) in the Gulf of Mexico and the Chesapeake Bay. This year’s predicted elevated flood risk in the Upper Midwest and the Ohio River Valley may result in a larger hypoxic […]

New Research Defines Origin and Dynamic Behavior of Gulf of Mexico Dead Zone

Reducing the size of the widespread area of hypoxia (low oxygen) in the northern Gulf of Mexico—known as the “Dead Zone”—represents one of the nation’s crucial water management challenges. Recent NCCOS-sponsored research has led to the development of a new tool to assess hypoxia formation and its response to key physical and biological drivers. Dr. […]

Could Future Land Use Changes Increase Storm Surge Flooding?

Scientists funded by the National Centers for Coastal Ocean Science have found that projected changes in coastal Gulf of Mexico land use and land cover could increase the extent of storm surge flooding by up to 70 percent above flooding from projected sea level rise alone. Using a newly developed predictive model, the University of […]

Common Brevetoxin Metabolite Found in Gulf of Mexico Oysters May Not be a Health Risk

Brevetoxin B2—an abundant shellfish metabolite of brevetoxin found in Gulf of Mexico oysters—does not readily pass through an intestinal barrier, rendering it unlikely to cause neurotoxic shellfish poisoning. The B2 metabolite is produced by oysters and many other animals by attaching the amino acid cysteine to the brevetoxin that is consumed by shellfish during blooms […]

Sea Level Rise Research Supports Gulf of Mexico Sentinel Site Cooperative

An NCCOS-funded study is investigating the ecological effects of sea level rise in the Gulf of Mexico. The effort is the focal point of the Northern Gulf of Mexico Sentinel Site Cooperative, a federal–state partnership established to advance sea level rise prediction and assessment capabilities. The cooperative seeks to improve coastal data and research products […]

Research Shows Shellfish Metabolism of Red Tide Toxin Can Change the Outcome of Poisoning

As recent as 2012, the State of Texas was impacted by the longest red tide on record, leading to the collapse of its oyster industry and  the Governor to seek disaster assistance from the U. S. Department of Commerce. A new study published in the American Chemical Society journal: Chemical Research in Toxicology shows that in animals the […]

Gulf of Mexico Dead Zone Research Coordination: NOAA Heads Forum in Support of Hypoxia Task Force

In overlapping venues on 17-18 April 2013, NCCOS co-led the Forum for Gulf of Mexico Hypoxia Research Coordination and Advancement, and represented NOAA at the U.S. Mississippi River Gulf of Mexico Watershed Nutrient (Hypoxia) Task Force Spring 2013 Public Meeting; both meetings aimed at advancing management mandates of the Hypoxia Task Force to reduce the […]

Spring Floods May Increase This Year’s Gulf of Mexico Dead Zone

To develop an earlier prediction of the size of the Gulf of Mexico “dead zone” this summer, NOAA’s National Weather Service and National Ocean Service combined data from the National Hydrologic Assessment U.S. Spring Flood Risk Outlook with knowledge of soil saturation and typical weather patterns throughout the Mississippi watershed this year. Based on estimates of flood risk, snow pack, […]
