Technology Transfer Between NOAA and France Improve Caribbean Ciguatoxin Detection

A PhD candidate from the French Research Institute for Exploitation of the Sea (IFREMER), Francesco Pisapia, is visiting the NCCOS Center for Coastal Fisheries and Habitat Research (CCFHR) for eleven weeks of intensive training on the method and technique of cytotoxicity assays to detect ciguatoxins (CTXs) and maitotoxins (MTXs) in fish tissue and cell cultures. […]

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 […]

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 […]

Harmful Algal Cyst Mapping in Washington Shows 10-fold Increase since 2013

An unprecedented bloom of the harmful alga Alexandrium occurred during Fall 2014 in Quilcene Bay, Hood Canal, Puget Sound, WA; the outbreak contaminated shellfish with potent biotoxins that can cause paralytic shellfish poisoning. The area of the bloom was historically biotoxin free, but at the peak of the event, the Washington State Department of Health detected toxin […]

NCCOS Prepares Toxin Sensor for Gulf of Maine Red Tide Forecasting

An NCCOS technical expert completed critical calibrations of the paralytic shellfish poisoning (PSP) toxin sensor for an Environmental Sample Processor (ESP) platform stationed at the Woods Hole Oceanographic Institution’s Laboratory for Ocean Sensors and Observing Systems (LOSOS). Beginning in early May, this ESP will perform autonomous, near real-time monitoring of toxins associated with cells of the red […]

Puget Sound Harmful Algal Blooms Linked to Seasonal Patterns and Survival Probability

In order to predict blooms and prevent undue economic loss of commercial shellfish in Puget Sound, NCCOS has sponsored research investigating the seasonal patterns and mechanisms of bloom formation of Alexandrium, a dinoflagellate that contaminates shellfish and causes paralytic shellfish poisoning (PSP) in humans. The study shows Alexandrium survives and spreads in Puget Sound in response to […]

Hypoxia Special Session Lead by NCCOS at 2015 Aquatic Sciences Meeting

Leading a special session on advances in hypoxia modelling, scientists from NCCOS contributed to the global mission of the 2015 Aquatic Sciences (ASLO) Meeting in Grenada, Spain which focused on global and regional patterns of aquatic systems. The hypoxia special session highlighted diverse modeling approaches to a variety of issues from the development of hypoxia […]
