Guam Students Learn About Coastal Resilience and Conservation

Over a decade ago, fishermen in the village of Umatac (Humåtak) off the southwest coast of Guam found they were not catching the same size and quality of fish. Researchers identified one of the primary reasons to be an accelerated rate of erosion caused by the introduction of feral ungulates (pigs, goats, and deer) and […]

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 […]

Ocean Sciences Meeting Highlights Results of Sponsored Research

The 2014 Ocean Sciences Meeting showcased the reach and extent of research sponsored by NCCOS, including coral reefs, harmful algal blooms, hypoxia, applying research to management solutions, and integrated ecosystem assessments. NCCOS staff and sponsored research scientists gave over 25 oral and poster presentations and co-chaired a special session on mapping, monitoring, and managing mesophotic […]

Climate-based Integrated Ecosystem Assessments for Ocean Resource Management

A special issue of the journal Oceanography published in March highlights a number of accomplishments and findings of the U.S. component of the Global Ocean Ecosystems Dynamics (GLOBEC) program. For over 20 years, this multidisciplinary research program initiated by the United Nations conducted research in the U.S. and around the world, focusing on the potential […]

NCCOS Scientist Receives Prestigious Award

Dr. William Sunda will be awarded the elite honor of fellow in the Geochemical Society and the European Association of Geochemistry. The award will be presented in June at the Goldschmidt Conference in Sacramento, Calif., the annual meeting hosted jointly by both societies. The award honors outstanding scientists who have, over some years, made a […]

New Report Addresses Re-eutrophication and Hypoxia in Lake Erie

A new report aimed at Great Lakes policymakers calls for Lake Erie total phosphorus reductions almost 50 percent greater than previous recommendations. Recent total phosphorus reduction recommendations may not reduce hypoxia (low dissolved oxygen) as called for by the Great Lakes Water Quality Agreement undertaken by Canada and the United States. Reducing total phosphorus loading […]

Working to Reduce Toxic Blue-Green Algal Blooms in Chesapeake Bay

NCCOS-sponsored researchers recently explored several promising techniques to mitigate toxic cyanobacteria (blue-green algae) blooms in the Chesapeake Bay region. The team focused on sediment-flocculation, in which local sediments and commercial clays are combined with the flocculating compound chitosan to sink and bury Microcystis cyanobacteria blooms. Other techniques evaluated included post-bloom flushing and early spring deployment of […]
