Origin of Toxic Red Tides in Texas Identified

New modelling research sponsored by NCCOS shows that Texas red tides originate in the southwestern Gulf of Mexico in the Bay of Campeche. These harmful algal blooms, caused by the dinoflagellate alga Karenia brevis, result in large fish kills, human respiratory irritation, and shellfishing closures in affected areas. Unlike red tides on the west coast […]

NCCOS Prepares Toxin Sensor for Deployment in Puget Sound, WA

NCCOS scientist, Tina Mikulski, completed critical calibration of the domoic acid (DA) toxin sensor on an Environmental Sample Processor (ESP) platform located at NOAA’s Northwest Fisheries Science Center (NWFSC) in Seattle, Washington. This ESP (referred to as ‘ESPfriday’) will be deployed for the first time in Puget Sound beginning in early August and will generate autonomous, […]

Assessing the Florida Keys National Marine Sanctuary: Blog Post

by Jen Maucher Fuquay During the past week I’ve  been a part of the Ecosystem Assessment Survey cruise through the Florida Keys National Marine Sanctuary (FKNMS) aboard the NOAA ship Nancy Foster.  Everyone has been working hard around the clock (literally!) collecting various sample types that will be analyzed as indicators of the health of […]

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 […]

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 […]
