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 […]

Toxic Algae Maps Aid Galveston Fish Kill Response

A scientist will map the extent of a red tide bloom during the course of a hypoxia-mapping project cruise funded by the National Centers for Coastal Ocean Science’s Gulf of Mexico Ecosystems & Hypoxia Assessment program.  The bloom, which was discovered August 10, caused massive fish kills and respiratory and eye irritation along the upper Texas coast.  Local […]

Big Drought Makes for a Small ‘Dead Zone’ – NYTimes.com

In yet another display of the inexorable interdependence of Earth’s ecosystems, a bad summer for Midwestern farmland has turned out to be a good one for life in the Gulf of Mexico. Researchers from the Louisiana Universities Marine Consortium have found that this summer’s hypoxic zone in the Gulf of Mexico – the oxygen-devoid area […]

Dearth of Heartland Rainfall Linked to Smaller Gulf of Mexico Dead Zone

Last weekend, media outlets reported a NOAA announcement that this year’s Gulf of Mexico low oxygen ‘dead zone’ is the fourth smallest since 1985. A severe drought baking the nation’s midsection is responsible for less nutrient-laden Mississippi River water that triggers the annual phenomenon. By contrast, last year’s floods resulted in low oxygen over an […]

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. […]

2 Very Different Forecasts For Gulf ‘Dead Zone’ « CBS Dallas / Fort Worth

Scientists from Louisiana and Michigan have wildly different predictions for the size of this year’s “dead zone” of low-oxygen water in the Gulf of Mexico. Forecasts released Thursday say it will either be the smallest in nearly a quarter century at just under 1,200 square miles, or five times that big and a bit above […]
