Study of Freshwater Turtles to Improve Treatment of Toxins in Sea Turtles

New research is paying off long-term for endangered sea turtles facing illness and even death during Florida red tides. From 2011-2014, the NCCOS sponsored project “Brevetoxin Metabolism and Physiology – A Freshwater Model of Morbidity in Endangered Sea Turtles” used non-endangered freshwater turtles as models to determine the effects of Florida red tide on endangered sea […]

Robots Help Locate Origins of Shellfish Toxicity in Eastern Gulf of Maine

Scientists deployed four underwater robotic Environmental Sample Processors (ESPs) in the Bay of Fundy and the eastern Gulf of Maine at the end of last month. The ESPs count the Paralytic Shellfish Poisoning (PSP)-causing dinoflagellates, Alexandrium fundyense (aka New England red tide). The sensors test a critical hypothesis that A. fundyense cells originate in the Bay […]

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 […]

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 […]

NCCOS Joins USGS in Congressional Briefing on Harmful Algal Bloom Threats

On April 4, a Congressional Briefing held in Washington, DC, focused on harmful algal blooms (HABs) and their increasing impacts on coastal, Great Lakes, and inland communities and economies. NCCOS’ Quay Dortch, represented NOAA as a featured panelist, discussing the growing problem of marine HABs and the threat posed by freshwater HABs (i.e., cyanobacteria or […]

International Collaboration Investigates Ciguatoxin Toxicity Around the Globe

The first assessment of toxicity differences among the many known Gambierdiscus strains or species responsible for Ciguatera Fish Poisoning (CFP) in humans from consumption of fish contaminated with ciguatoxin was published in Harmful Algae. The international effort was led by Francesco Pisapia from IFREMER and included scientists from NOAA’s National Centers for Coastal Ocean Science, […]

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 […]
