Galveston Bay Closed to Oyster Harvesting After Scientists Detect Toxic Algal Bloom

The Texas Department of State Health Services is temporarily closing all of the Galveston Bay system to the harvesting of oysters, clams, and mussels because of elevated levels of an alga that can produce a toxin in some shellfish. NCCOS-funded scientists at Texas A&M University detected the harmful algal bloom and notified the state agency, […]

Identifying Origin and Mechanism of Texas Red Tide

A study funded by the National Centers for Coastal Ocean Science has tentatively identified the source and control mechanism of red tides (Karenia brevis) along the Texas coast. The research, led by Texas A&M University, incorporates a suite of linked models (e.g., biological–physical), combined with data from drifting sensors, satellites, and an automated underwater microscope […]

Surface Elevation Trends Help Us Prepare for Climate Change

Predicting future patterns of coastal inundation from sea level rise requires knowledge of changes in sea level and changes in elevation of land surface. Surface elevation tables—mechanical devices permanently installed in wetlands—allow scientists to measure small changes in surface elevation precisely and accurately. These devices have been installed in coastal wetlands across the U.S. by […]

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 […]

Marine Cage Aquaculture Report Addresses Environmental Concerns

Over 50 percent of seafood production globally comes from aquaculture. While technological innovation has made it possible to grow food in the coastal and open ocean, managers must weigh economic and food security benefits against environmental risks. A report, Marine Cage Culture and the Environment: Twenty-First Century Science Informing a Sustainable Industry, developed by the […]
