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 […]

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 […]
