United States Harmful Algal Bloom Control Technolo...

The development of scale appropriate technologies that can be used to control the growth and spread of harmful algal blooms (HAB) has lagged the advances in understanding the factors that ...

Upwelling and Coastal Land Use Patterns on the Dev...

We are comparing coastal “hot spots” of harmful algal blooms (HABs) in central and southern California to determine why hot spots exist and how human influences, such as nutrient runoff, ...

Using Microcystin-degrading Bacteria and their Enz...

We will assess the potential that algal toxin–degrading bacteria have to degrade toxins from water treatment facilities. Why We Care Harmful algal blooms (HABs) occur in eutrophic waters across the ...

Validating the Technique for Identifying Paralytic...

Paralytic shellfish poisoning (PSP) is a world-wide, sometimes fatal seafood poisoning caused by potent algal neurotoxins that accumulate in shellfish. Most nations have certified shellfish PSP testing programs required for ...

Validation of a Triplex Test for Saxitoxin, Domoic...

We will evaluate an assay that simultaneously detects paralytic shellfish poisoning, amnesic shellfish poisoning, and diarrhetic shellfish poisoning toxins in mussels.  Why We Care Shellfish aquaculture is a large and ...

Value of the Pacific Northwest Harmful Algal Bloom...

We will estimate the economic benefits of the Pacific Northwest Harmful Algal Bloom Bulletin, using a methodology that quantifies the value of information. Why We Care The razor clam and ...

Value of the SoundToxins Partnership: An Early War...

We will estimate the net economic benefits of the harmful algal bloom early warnings provided by SoundToxins and evaluate net economic benefits to recreational shellfish harvesters. Why We Care A ...

National Harmful Algal Bloom Observing Network Fra...

The National Harmful Algal Bloom Observing Network (NHABON) Framework offers a high-level regional analysis of existing efforts to monitor and forecast harmful algal blooms (HABs) and identifies gaps in observing ...

Reviews of Our Current Understanding of Harmful Di...

In a recently released book on dinoflagellates, three chapters update knowledge of and changing views for the red tide alga Karenia brevis and the estuarine Pfiesteria-like dinoflagellates Pfiesteria piscicida and ...

Marine Heatwaves Fuel Harmful Algal Blooms Off US ...

Recreational razor clamming can bring thousands of visitors to the Washington coast. Toxins concentrated in razor clam and Dungeness crab fisheries have caused economic damage to coastal communities. Repeated marine ...

NCCOS Supports Expansion of Red Tide Respiratory F...

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 Supports Inception of Harmful Algal Bloom Mo...

Clams are gathered for testing in Southeast Alaska. Photo Credit: Bethany Goodrich, Southeast Sustainable Partnership Alaska Natives rely on a variety of marine resources, including shellfish, as part of their ...

NCCOS-developed Algal Toxin Sensor Deployed in New...

Working with colleagues at the Woods Hole Oceanographic Institution (WHOI), NCCOS scientists have calibrated and deployed NCCOS-developed domoic acid (DA) sensors on two Environmental Sample Processors (ESPs) in New England ...

Linking Chlorophyll Concentration and Wind Pattern...

The California Current System (CCS) is a highly productive region because of wind driven upwelling which supplies nutrients to the euphotic zone. Few studies have compared upwelling and algae blooms ...

Working Group Releases Progress Report on Harmful ...

The Interagency Working Group on Harmful Algal Bloom and Hypoxia Research and Control Act (IWG-HABHRCA) has released a report to Congress that provides a comprehensive summary of all current federal ...
