An Early Warning System for Pseudo-nitzschia Harmf...
Blooms of some species of the diatom Pseudo-nitzschia produce a neurotoxin that accumulates in shellfish, which can cause illness and even death in humans who eat them. Shellfish managers monitor ...
Effects and Discovery of Chronic Domoic Acid Expos...
Domoic acid, a naturally occurring marine neurotoxin, threatens the health of marine mammals, seabirds, and humans via severe and long-term yet low-level exposure through the food web. Researchers discovered a ...
Emerging Algal Toxins in the California Current Sy...
Surveys in California have highlighted the occurrence of HAB toxins in estuarine waters and shellfish, but there is concern that current monitoring approaches under-report the threats. There is a need ...
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 the Southeast Alaska Tribal Ocean Resear...
This project expands existing harmful algal bloom (HAB) monitoring conducted by the Sitka Tribe of Alaska Environmental Research Laboratory (STAERL) to include testing shellfish for domoic acid and diarrhetic shellfish ...
Oceanographic and Cellular Controls on Domoic Acid...
Domoic acid is a neurotoxin produced by some diatoms in the genus Pseudo-nitzschia. Domoic acid can accumulate in shellfish and fish, and cause illness or death in humans, marine mammals, ...
RAPDALERT – Rapid Analysis of Pseudo-nitzschia and...
Through this pilot project in the coastal waters of Southern California, we demonstrated the effectiveness of adding emerging technologies to harmful algal bloom monitoring programs that focus on toxic blooms ...
Strengthening Early Warning and Forecasts of Domoi...
In the Pacific Northwest (PNW), blooms of Pseudo-nitzschia that produce domoic acid (DA) are a significant human health threat and extremely costly to coastal communities. This project improves early warnings ...
The Columbia River Plume and Harmful Algal Blooms ...
We identified the oceanographic causes and transport routes for the harmful alga Pseudo-nitzschia in the offshore waters of the Pacific Northwest and improved predictability of the arrival of harmful algal ...
Trophic Transfer and Effects of HAB Toxins in Alas...
This project aims to determine harmful algal bloom species composition and cell densities in Alaskan waters, and to model toxin transfer pathways to zooplankton, shellfish, finfish, and marine mammals, and ...

Long Term Research on the HAB Toxin Domoic Acid In...
A coalition of researchers funded by the NOAA Monitoring and Event Response for Harmful Algal Blooms (MERHAB) Program recently came together to co-locate an Environmental Sample Processor (ESP) off the ...
Ice Seals as Sentinels for Algal Toxins in the Pac...
An NCCOS-supported study detected the algal toxins domoic acid and saxitoxin in three out of four species of ice seals in western and northern Alaska. The finding suggests that ice ...
Report on U.S. Marine HABs: History, Current Statu...
NCCOS recently supported a review of the status of marine HAB problems in the U.S., part of a global statistical analysis of harmful algal blooms (HAB) events. The study relies ...
Environmental Sample Processor Enhances Ocean Sens...
In a study published recently in the Journal of Marine Science and Engineering, NCCOS and Northwest Fisheries Science Center researchers, along with partners at the University of Washington (UW), and ...
HAB Bulletin Supports Quinault Tribal Access to Ra...
On April 12, 2021, the Quinault Indian Nation welcomed tribal razor clam diggers to Mocrocks Beach, Washington. This is the first time tribal members have been able to access this ...
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 ...
NCCOS Science, Funding are Backbone of U.S. HAB Mo...
NCCOS-supported regional harmful algal bloom (HAB) monitoring programs span the United States and help build a global HAB monitoring and prediction system. A recent article in Frontiers in Marine Science ...
Why are Toxic Pseudo-nitzschia Blooms Increasing i...
In the Gulf of Maine (GOM), the presence of the toxic diatom genus Pseudo-nitzschia (PN) is growing. Unprecedented levels of domoic acid in 2016 led to the first Amnesic Shellfish ...
Pacific Northwest HAB Forecast Supports Popular Re...
Razor clamming at Twin Harbors beach, WA. Credit WDFW NOAA funded partners released the latest Pacific Northwest Harmful Algal Blooms (PNW HAB) Forecast one week ahead of a three-day razor ...
