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, […]

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 […]

Getting the Word Out: Sharing the Benefits of Shellfish Aquaculture

Different aspects of shellfish aquaculture science were recently shared on three separate occasions with regional groups that varied from industry partners to regional growers to high school students. These presentations are part of an effort to communicate best practices of shellfish aquaculture to the public and stakeholders so that these methods will be employed in […]

Association of Marine Lab Conference Features Caribbean Ciguatera Research

To raise awareness about a resurgence of Ciguatera Fish Poisoning (CFP) in the Caribbean and the current state of ciguatera research, NOAA’s National Centers for Coastal Ocean Science (NCCOS) led a special session on ciguatera at the Association of Marine Laboratories of the Caribbean 37th Scientific Conference in Willemstad, Curaçao, during the week of May […]

New Indicator for Gulf of Mexico Toxic Alga Shows Promise

NCCOS-sponsored scientists have discovered a simple indicator to predict one type of harmful algal species bloom or outbreak. The first potentially reliable biological indicator for forecasting a harmful algal bloom of the toxic dinoflagellate species Dinophysis ovum in the Gulf of Mexico is the presence of a primary food source, a small ciliate protozoan. The […]

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 […]
