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

Scientists are expecting an average, but still large, hypoxic or “dead zone” in the Gulf of Mexico this year, and a slightly above-average hypoxic zone in the Chesapeake Bay. NOAA-supported modeling is forecasting this year’s Gulf of Mexico hypoxic (very low oxygen) zone to cover an area ranging from 4,633 to 5,708 square miles (12,000 […]

Gliders Map Gulf of Mexico Dead Zone

This summer, NCCOS-sponsored scientists from Texas A&M University will test the use of gliders to monitor and map hypoxia in the northern Gulf of Mexico. The team will deploy five autonomous underwater vehicle gliders and one autonomous surface vehicle over the Louisiana coastal shelf and associated offshore region, while also taking shipboard hypoxia (low dissolved […]

Scenario-based Ecosystem Forecast Models Help Mitigate Hypoxia

Representing NOAA at the Ninth National Monitoring Conference, NCCOS’s Dr. Alan Lewitus spoke at a session focused on nutrient monitoring and modeling to restore and protect coastal water quality. His presentation described how scenario-based ecosystem forecast models can generate nutrient reduction targets to achieve hypoxia mitigation goals. NCCOS administers national competitive programs that assess the […]

Glider Implementation Plan Provides Blueprint for Improved Monitoring of Gulf of Mexico Dead Zone

The Glider Implementation Plan for Hypoxia Monitoring in the Gulf of Mexico is now available to guide the use of autonomous underwater vehicles for enhanced monitoring of seasonal hypoxia in the northern Gulf of Mexico. The need for improved monitoring of the hypoxic zone (dead zone) has been repeatedly emphasized by the Interagency Gulf Hypoxia Task […]

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 […]
