ECOHAB, Florida, Forecasting, Gulf of Mexico, Gulf of Mexico, harmful algal bloom, Harmful Algal Bloom Detection and Forecasting, Karenia brevis, marc.suddleson@noaa.gov, Other Topics, Sponsored Research, Stressor Impacts and Mitigation, U.S. States and Territories, Waterbodies

An extensive bloom of the brevetoxin-producing Karenia brevis occurred from 2017 to 2019 in Florida. The economic, environmental, and human health impacts were quite severe ...

Life and Death of a Karenia Bloom in the Western Gulf of Mexico

Forecasting, Gulf of Mexico, harmful algal bloom, Harmful Algal Bloom Detection and Forecasting, IFCB, Karenia brevis, marc.suddleson@noaa.gov, Other Topics, Sponsored Research, Stressor Impacts and Mitigation, Texas, TOAST, U.S. States and Territories, Waterbodies

Harmful algal blooms (HABs) are increasing in frequency and pose a threat to human and environmental health. Blooms of Karenia brevis occur nearly annually along ...

Linking Biogeochemistry to Harmful Algal Bloom Nutritional Physiology with Gene Expression Analysis: Brown Tide

Aureococcus, Biological Effects of Contaminants and Nutrients, brown tide, ECOHAB, harmful algal bloom, Harmful Algal Bloom Detection and Forecasting, New York, Other Topics, quay.dortch@noaa.gov, Sponsored Research, Stressor Impacts and Mitigation, U.S. States and Territories

The Long Island Brown Tide (LIBT) threatens shellfish and sea grasses in mid-Atlantic estuaries. LIBT-specific gene expression assays are being developed and tested for enzymes ...

Linking Models and Field Experiments to Forecast Algal Bloom Toxicity in Lake Erie

felix.martinez@noaa.gov, Great Lakes, Harmful Algal Bloom Detection and Forecasting, Michigan, New York, Ohio, Pennsylvania, Stressor Impacts and Mitigation, U.S. States and Territories, Waterbodies

We are investigating the links between environmental variables and harmful algal bloom (HAB) toxins in Lake Erie to better understand the process of toxin development ...

Mechanism of Harmful Algal Bloom Initiation in the Western Gulf of Mexico

Forecasting, Gulf of Mexico, Gulf of Mexico, harmful algal bloom, Harmful Algal Bloom Detection and Forecasting, Karenia brevis, quay.dortch@noaa.gov, Stressor Impacts and Mitigation, Texas, U.S. States and Territories, Waterbodies
