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 […]

First Estimates of Trap Debris in Florida Keys National Marine Sanctuary Now Available

Over 85,000 spiny lobster ghost traps and over 1 million non-fishing traps or remnants of traps are estimated to be present on the seafloor of the Florida Keys National Marine Sanctuary. Researchers from the National Centers for Coastal Ocean Science and the Florida Fish and Wildlife Conservation Commission calculated these estimates following completion of 151 […]

Harmful Algal Bloom Intensity May be Tied to Ocean Carbon Dioxide Levels

Recent findings show that increases in oceanic carbon dioxidefrom the burning of fossil fuels over the last 200 years may have increased the intensity and toxicity of Karenia brevis blooms. Researchers from the National Centers for Coastal Ocean Science (NCCOS) report that this effect is projected to increase substantially by the turn of the century with […]

Texas Alerted to Toxic Pseudo-nitzschia Bloom in Galveston Bay

Volunteers with NOAA’s Phytoplankton Monitoring Network have reported a bloom of the diatom, Pseudo-nitzschia in Galveston Bay, Texas, and NOAA’s Analytical Response Team has confirmed that the bloom is producing domoic acid, a neurotoxin that can cause amnesiac shellfish poisoning. State managers of the Texas Parks and Wildlife Department and Texas Department of State Health […]

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. […]
