Application of Clay Flocculation for Removal of Ka...

Despite routine application in Asia, clay flocculation technology to control harmful algal blooms has not been adopted in the U.S., largely because of the lack of data on U.S. ecosystems ...

Assessing Societal Impacts of Harmful Macroalgae B...

We will examine how Sargassum seaweed blooms and their mitigation in the Caribbean affect multiple dimensions of social resilience, including economic impacts, human well-being, local ecological knowledge, and individual attitudes, ...

Characterization of an Algicidal Agent Produced by...

We examined a biological control agent isolated from a bacteria species that may provide a mechanism for halting the growth of certain types of toxic dinoflagellate harmful algal blooms. We ...

Deposition and Resuspension of Alexandrium fundyen...

Toxins from annual blooms of Alexandrium fundyense accumulate in shellfish; shellfish harvesting closures protect human health, but are economically disruptive. Seed-like cysts produced by A. fundyense accumulate in bottom sediments ...

Developing Practical and Affordable Water Filtrati...

We are testing the use of local, natural bacteria to destroy cyanotoxins. These toxins are produced by freshwater cyanobacteria, also known as blue-green algae, and they contaminate municipal water supplies ...

DinoSHIELD: A Slow-release Natural Algicide Produc...

We will field test an environmentally neutral method to control harmful algal blooms. Our work will provide managers with information on the applications of a natural algicide as an environmentally ...

ECOHAB: GOMTOX: Dynamics of Alexandrium fundyense ...

Extensive shellfish resources in the Gulf of Maine are frequently contaminated with toxins produced by the red tide dinoflagellate Alexandrium fundyense. Shellfish harvesting must be closed to protect public health ...

Enhancing Third-generation Environmental Sample Pr...

Monitoring the increase in cyanobacterial harmful algal blooms (HABs) in nearshore environments is challenging. Recent development of a long-range autonomous underwater vehicle (AUV) equipped with a third-generation Environmental Sample Processor ...

Evaluation of Mitigation Strategies for Harmful Al...

We will assess the potential economic benefits of mitigation strategies for harmful algal blooms in the Dungeness crab fishery along the U.S. West Coast. Why We Care In 2015, the ...

Expanding ISSC Validated Options for Monitoring Di...

In the U.S., the Interstate Shellfish Sanitation Conference (ISSC) and the Food and Drug Administration (FDA) establish methods of toxin analysis to regulate shellfish, and the National Shellfish Sanitation Program ...

Clay Treatments to Control Red Tide Unlikely to Ha...

Blooms of the toxic marine algae Karenia brevis, commonly known as red tide, occur almost annually on Florida’s west coast, often killing other marine life and costing local economies millions ...

NOAA Announces FY23 Notice of Funding Opportunity ...

Western Lake Erie True Color Image of a harmful algal bloom derived from Ocean and Land Color Instrument (OLCI) sensor on Copernicus Sentinel-b obtained from EUMETSAT. NOAA’s National Centers for ...

Natural Algicide Eliminates Toxic Algae With Minim...

NCCOS-sponsored research on a natural algicide produced by Shewanella bacteria found that the compound can kill toxic algae without much harm to other organisms. The findings suggest that nature itself ...

Harmful Algal Bloom Symposium Highlights Early Car...

HAB Toxin of Unknown Origin Linked to a Dinoflagel...

Dinophysis norvegica. Credit WHOI. The biological source of Dihydrodinopyhysistoxin-1 (aka dihydro-DTX1), a toxin that causes diarrhetic shellfish poisoning and once described from a marine sponge, is of yet unknown. In ...

NCCOS, IOOS Award $11.6 Million for Harmful Algal ...
