Portable Red Tide Detector Debuts at NOAA Emerging Technologies Workshop

A portable, hand-held instrument that uses genetics to detect the red tide-causing organism Karenia brevis in the field was featured at the second NOAA Emerging Technologies for Observations Workshop. The device, dubbed a “tricorder” after the fictional Star Trek hand-held life detector, is the first of its kind and is able to provide direct results […]

Study Provides Nutrient Reduction Targets to Reach Gulf Dead Zone Goal

The Mississippi River/Gulf of Mexico Hypoxia Task Force (HTF) has made major strides in reducing point source nutrient pollution in the Gulf of Mexico watershed, and had some success in mitigating nonpoint source pollution through targeted nutrient reduction projects.  However, despite this progress, research supported by NOAA’s National Centers for Coastal Ocean Science (NCCOS) has […]

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, […]
