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, […]

Mercury Levels in the Gulf of Mexico Quantified in NOAA Report

On August 29, researchers at the National Centers for Coastal Ocean Science (NCCOS) published an analysis of NOAA Mussel Watch Program contaminant monitoring data for mercury and methylmercury levels and distributions around the Gulf of Mexico. Data gathered from oyster and sediment samples from Texas to Florida revealed relatively elevated mercury concentrations (hotspots) in the […]

Dead Zones, Sea Level, Algae Blooms and Restoration Focus of Gulf Gathering

The importance of the Gulf of Mexico to the US economy is significant. The National Centers for Coastal Ocean Science has invested over $66M in public funds for research into harmful algal blooms, nutrient over-enrichment contributions to hypoxia, ecological effects of sea level rise (EESLR), and coral reefs in the Gulf of Mexico since 1990. […]

Rise in Asian Tiger Shrimp sightings prompts scientific look at invasion concerns | NOAA Press Release

The recent rise in sightings of non-native Asian tiger shrimp off the U.S. Atlantic and Gulf of Mexico coasts has government scientists working to determine the cause of the increase and the possible consequences for native fish and seafood in those waters. Researchers from the U.S. Geological Survey and National Oceanic and Atmospheric Administration are […]
