Scientists Expect Slightly Below Average Chesapeake Bay ‘Dead Zone’ this Summer

Low river flow and nutrient loading reason for smaller predicted size Scientists are expecting that this year’s Chesapeake Bay hypoxic low-oxygen zone, also called the “dead zone,” will be approximately 1.37 cubic miles – about the volume of 2.3 million Olympic-size swimming pools. While still large, this is 10 percent lower than the long-term average […]

NCCOS and NMFS Partner to Survey “Unprecedented” West Coast Toxic Algal Bloom

NOAA Fisheries announced it has mobilized extra scientists to join a fisheries survey aboard the NOAA Ship Bell M. Shimada charting an extensive harmful algal bloom (HAB) that spans much of the West Coast. An NCCOS sponsored Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) project in southern and central California comparing coastal HAB ‘hot spots’ analyzes water samples […]

NOAA “Science to Management” Project Trains Stakeholders in Coral Reef Forensics

NCCOS supported researchers led a May 2015 training event wherein local community members learned to use coral reef “forensics” on reef plants and animals. This activity identified and provided early warning of coral reef stress, death and decay causes. The event, hosted by the citizen conservation group Maui Nui Marine Resource Council on the Hawaiian […]

NOAA, partners predict an average ‘dead zone’ for Gulf of Mexico

Outlook incorporates multiple hypoxia models for first time Scientists are expecting that this year’s Gulf of Mexico hypoxic zone, also called the “dead zone,” will be approximately 5,483 square miles or about the size of Connecticut–the same as it has averaged over the last several years. The dead zone in the Gulf of Mexico affects […]

Persistent Organic Pollutants Unlikely Cause of Dolphin Health Issues after Deepwater Horizon

NCCOS scientists reported that persistent organic pollutants (POPs) were likely not a contributing factor to the poor health conditions and increased mortality observed in some populations of bottlenose dolphins following the Deepwater Horizon (DWH) oil spill.  This study, recently published in the journal Science of the Total Environment, analyzed 169 remote biopsy samples that were […]

NCCOS Scientists Assess Chemical Contaminants in Cocos Lagoon

NCCOS scientists recently traveled to Guam for a project funded by NOAA’s Coral Reef Conservation Program (CRCP), to help quantify chemical contamination in Cocos Lagoon, located at the southern tip of the island.  Working with local partners, including the Guam Environmental Protection Agency, Guam Department of Agriculture, the University of Guam, NOAA NMFS and CRCP, […]

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 […]
