2013 Gulf of Mexico Dead Zone Size Above Average But Not Largest

National Centers for Coastal Ocean Science supported scientists have documented that the 2013 “dead zone”(area of hypoxia, or low oxygen) in the northern Gulf of Mexico west of the Mississippi River delta now covers at least 5,800 square miles of sea floor or about the size of the State of Connecticut. This dead zone area […]

Low Levels of Chemical Contaminants Found in Sediments of the Northwestern Gulf of Mexico

A new report is available summarizing the findings of an NCCOS-funded survey of sediments and overlying waters of the northwest Gulf of Mexico continental shelf, conducted in August 2011. The study found no evidence of biological impacts linked to poor sediment quality. Low values of species richness and diversity of sediment-dwelling benthic organisms were associated […]

NCCOS-funded Research Cruise Investigates Coral and Fish Connectivity in the Gulf of Mexico

On August 13, 2013, NCCOS and partners will set off on a two-week research expedition off the coast of southwest Florida to investigate the role of mesophotic (mid-depth) coral ecosystems of Pulley Ridge in replenishing key fish and other coral ecosystem species found in Florida Keys and Dry Tortugas reefs. This 5-year study, led by University of […]

NOAA and Partners Issue 2013 Dead Zone Predictions for Gulf of Mexico and Chesapeake Bay

Today, NOAA and partners issued the 2013 dead zone predictions for two of the nation’s most hypoxia-impacted bodies of water: the Gulf of Mexico and the Chesapeake Bay. The Gulf of Mexico hypoxic “dead” zone is predicted to be large this year, with an area ranging from 7,286 to 8,651 square miles. The upper end would […]

Managing America’s Corn Belt to Restore the Gulf of Mexico and Prairie Birdlife

NCCOS is participating in a public-private program to reduce nutrient inputs to the Gulf of Mexico hypoxic (“dead”) zone that managers expect to simultaneously benefit threatened native grassland bird species in steep decline The Eastern Tallgrass Prairie and Big Rivers Landscape Conservation Cooperative  (ETPBR LLC) is proposing a “Gulf Hypoxia Restoration Incentive Program” to reduce […]

Blood Monitoring Supports Response and Rehabilitation of Algae-poisoned Sea Turtles

Sea turtles in the Gulf of Mexico are long-lived animals that are valuable indicator species of environmental health. They are subject to multiple hazards, such as pollutants and natural toxins, including the algae-produced brevetoxin. NCCOS scientists who pioneered the use of blood collection cards are working in cooperation with wildlife managers in Florida to measure […]

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 […]
