Hypoxia Leads to Pathological, but Reversible, Changes in Fish Brains

The NCCOS sponsored project, Modeling Reproductive and Population Impacts of Hypoxia in the Northern Gulf of Mexico, led by the University of Texas at Austin, is investigating the impacts of low levels of dissolved oxygen on the brain functions of the Atlantic croaker, a common estuarine and coastal fish inhabiting the east coast of the United States. […]

NOAA Seminar Series Features Patuxent River Shellfish Aquaculture and Eutrophication Research

A scientist from NCCOS’s Center for Coastal Monitoring and Assessment described a modeling study in Chesapeake Bay region’s Patuxent River Estuary at the NOAA NOS Science Seminar Series on June 3, 2015. The presentation, titled “Shellfish Aquaculture: A Strategy for Eutrophication Mitigation in the Patuxent River,” reported nitrogen removal estimates through cultivation and harvest of oysters […]

Palau Sustainable Fisheries Supported by NCCOS Science

Recent findings from research conducted in Palau show that in order to manage reef fisheries, both good water quality and an intact biological community are needed.  Their results show that fish larvae respond to both reef sounds and the smells when seeking a place to settle from open water and mature into adults. This NCCOS-supported […]

Oceanic Continental Margin Dead Zones Emerge as Threats to Coastal Waters

Declines in oxygen levels of coastal waters have accelerated in recent decades creating “dead zones” not only in more publicized nearshore areas but in open ocean offshore regions of the continental shelves and slopes. Once treated as separate phenomena and distinct fields of study, scientists now see offshore and coastal hypoxia as interconnected, resulting in […]

Studying Contaminants in Cocos Lagoon, Guam: Blog Post #3

For sediment sampling in Cocos Lagoon, we used what is known as a “stratified–random design.” Basically, a series of strata (layers) were developed in consultation with local partners, and then random sampling points were scattered in each stratum. At these points, samples of sediment could be collected. By using this design, any point within a […]

Sea Star Wasting Disease Discovered in Alaska

Researchers from NCCOS and the University of Alaska Fairbanks School of Fisheries and Ocean Sciences found evidence of sea star wasting disease in Alaska while surveying intertidal areas near NOAA’s Kasitsna Bay Laboratory. The team found the diseased sea stars during long-term monitoring surveys conducted under the Gulf Watch Alaska program at sites around Elephant […]
