Why the Exceptional Toxicity during the 2015 West Coast Harmful Algal Bloom?

New research sponsored by NCCOS explains what might have caused the high toxicity in Monterey Bay, CA during the massive 2015 toxic bloom of the marine diatom Pseudo-nitzschia along the West Coast of the United States. Based on NCCOS research, warm water, nutrients, or a combination of factors may have caused the bloom and to some extent […]

Second ‘Cytobot’ Deployed in Texas Harmful Algae Early Warning Sensor Network

NCCOS-funded investigators from Texas A&M University (TAMU) successfully deployed an Imaging Flow Cytobot (IFCB) on a pier near Freeport, Texas. This is the second cytobot deployed in the Gulf of Mexico as part of an expanding cytobot network to provide early warning of harmful algal blooms (HABs) that impact coastal resources. Blooms of Karenia brevis, […]

NCCOS Responds to Southern California Harmful Algal Bloom Event

Starting late March- early April 2017, researchers, managers, and animal response networks working in Southern California coastal communities noted an increase in wildlife impacts consistent with the onset of a harmful algal bloom (HAB). They observed a large die-off of seabirds in Santa Barbara, Ventura, and Los Angeles Counties and an influx of sea lions […]

NCCOS Research Featured in EPA Harmful Algal Blooms Regional Forum

Southwestern states and Pacific Islands are experiencing increasing occurrences of harmful algal blooms in both coastal ocean and freshwater bodies. Recently the U.S. Environmental Protection Agency (EPA) in collaboration with a key regional partner, the California Surface Water Ambient Monitoring Program, convened a forum for federal, state, tribal and local agencies, lake managers, and water […]

Toxin Sensor off Washington Coast Provides Early Warning

A sensor for the algal neurotoxin domoic acid (DA), developed by NCCOS scientists, was deployed last week off the Washington coast on an Environmental Sample Processor (ESP). Designed by the Monterey Aquarium Research Institute (MBARI) and known as “ESPfriday,” the processor is operated by the Northwest Fisheries Science Center (NWFSC). The DA sensor, along with harmful […]

Renewed Interest to Study Ciguatera Risks in Papahanaumokuakea Marine National Monument

Dr. Alison Robertson, an NCCOS ECOHAB sponsored ciguatera expert with the University of South Alabama and Dauphin Island Sea Lab (USA\DISL), is helping the NOAA Office of National Marine Sanctuaries (ONMS) assess human health threats related to ciguatera fish poisoning in island waters within the Papahanaumokuakea Marine National Monument (PMNM). Ciguatera is a major, if not the […]

Multiple Marine and Freshwater Algal Toxins Documented in Southern California

NCCOS-sponsored scientists recently documented the occurrence of several, potentially harmful cyanobacteria and associated toxins at the land-sea interface along the southern California coast. Their newly published findings in the journal Toxins reveal a previously unrecognized, potential human health threat from cyanotoxins in our coastal waters, raising new concerns for recreation, harvesting of finfish and shellfish, […]
