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 […]

U.S. and Korea Identify Marine Aquaculture Collaboration Opportunities

Representatives from the NOAA Aquaculture Program, including OAR, NOS, and NMFS, met last week with Korean government officials from National Fisheries Research and Development Institute (NFRDI) in Jeju, Korea to identify joint science priorities for marine aquaculture.  Both nations are working to develop sustainable aquaculture practices in coastal zones including the coastal ocean.  Priorities for collaborative […]

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 […]

Sensor Provides Early Warning of Toxic Algal Bloom in Offshore Waters of Monterey Bay

NCCOS-developed domoic acid sensors on board two Environmental Sample Processors (ESPs) deployed in Monterey Bay, California have provided early warning of a toxic Pseudo-nitzschia algal bloom. Only a week into the deployment that began in early May, particulate domoic acid levels exceeded 30 micrograms per liter of seawater, which was consistent with the ESPs also detecting very high concentrations […]

NCCOS Trains Partners to Conduct Coral Reef Monitoring Surveys for 2015 Field Season

NCCOS staff recently trained partners in field operations and fish and coral data collection for the National Coral Reef Monitoring Program (NCRMP), a core component of NOAA’s Coral Reef Conservation Program. Approximately seventy scientists from St. Thomas, USVI and the U.S. East Coast received classroom and practical instruction on protocol execution, in situ implementation, and data management to prepare […]

NCCOS Methods Transferred to Algal Toxin Testing Laboratory in Oman

NCCOS researcher Tod Leighfield trained three scientists with Oman’s Ministry of Agriculture and Fisheries in standard sample preparation and toxin detection methods as part of an International Atomic Energy Agency–funded project to establish a harmful algal bloom testing laboratory in the Arabian Gulf region. The training included assistance with set up of the laboratory and instruction on […]
