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 […]

Record-setting Razor Clam Harvest Aided by Pacific Northwest HAB Forecast

Recreational razor clam harvesters in Long Beach, Washington, set a record for one-day digger trips (17,800 diggers) on April 30, 2017. The record number of trips was triggered by the Washington Department of Fish and Wildlife’s (WDFW) first-ever decision to increase the bag limit on razor clams. One factor WDFW considered in making this decision […]

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, […]

Great Lakes Conference Highlights NCCOS Research

The International Association for Great Lakes Research’s (IAGLR) annual Conference on Great Lakes Research showcases the latest findings on the Great Lakes and other large lakes around the world. This year’s conference, held last month in Detriot, Michigan, highlighted a range of NCCOS research, including: ecological forecasting, remote sensing, habitat mapping, modeling, harmful algal blooms, chemical […]

Native Alaskans Trained in Potentially Life-saving Toxin Monitoring

Recent analyses conducted by the Sitka Tribe of Alaska Environmental Research Laboratory (STAERL) identified lethal levels of algal-produced toxin-like activity in shellfish from two Southeast Alaska sites in late May. Blue mussels, cockles, and butter clams were found to contain up to 46 times the regulatory limit for saxitoxins. Results from testing were shared with […]
