Projects

Rapid Detection of Harmful Algae

To provide coastal managers with the early warning needed to implement timely and effective mitigation strategies to reduce a harmful algal bloom’s negative impacts, we are producing rapid, easy-to-use kits ...

Rapid, Portable, Multiplexed Detection of Harmful ...

We are expanding algal toxin testing to include tests for saxitoxins and anatoxin-a. The new tool will give water managers and community-based monitoring networks the ability to rapidly quantify these ...

Resolving the Effects of Resource Availability, Pr...

Aureococcus anophagefferens causes brown tides that have severely impacted fisheries, seagrass beds, and aquaculture in mid-Atlantic US coastal waters for three decades. The recent sequencing of the Aureococcus genome, combined ...

Robotic, Underwater Sensor for Harmful Algal Bloom...

We developed a device to provide resource managers and public-health officials with valuable, real-time data on harmful algal bloom (HAB) toxicity. This robotic, underwater sensor provides fast and accurate measurements ...

Seasonal Forecasting of Karenia brevis Red Tide Bl...

This project is developing modeling tools to improve short term and seasonal predictions of toxic red tide Karenia brevis blooms in the Gulf of Mexico West Florida Shelf. The project ...

Sharing Simple and Fast Algal Toxin Detection Test...

Toxins produced by harmful algae accumulate in shellfish, causing human illness and marine animal mortalities. We have developed a rapid, cost-effective test that measures algal toxins in shellfish to protect ...

Shellfish Killers: An Optimized Early Warning Prog...

We are collecting data to understand the impacts of shellfish-killing algae and their toxins on aquaculture farms and wild populations and to develop a warning system for growers and managers ...

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 ...

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 ...

Phytoplankton Monitoring Network: 20 Years of Citi...

The National Phytoplankton Monitoring Network (PMN) is celebrating 20 years of improving harmful algal bloom (HAB) research through its citizen science monitoring efforts. The program has supported a national community-based ...

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 ...

Comparing Saginaw Bay and Western Lake Erie for Ha...

MODIS satellite image (undated) of Lake Huron/Saginaw Bay and the Western Lake Erie basin showing cyanobacterial blooms (greenish areas), Credit NASA. Scientists from NCCOS and the University of Maryland collaborated ...

NCCOS Assists Response to Quantify Toxin Accumulat...

NOAA’s National Centers for Coastal Ocean Science (NCCOS) provided a harmful algal bloom (HAB) Event Response award of $15,482 to the University of Florida, Florida’s Clinic for the Rehabilitation of ...

U.S. Socio-economic Effects of Harmful Algal Bloom...

NCCOS Competitive Research Program (CRP) and the U.S. National Office for Harmful Algal Blooms at the Woods Hole Oceanographic Institution (WHOI) released proceedings from a 2020 workshop on the socio-economic ...

New Study Describes Transport of Toxic Freshwater ...

An NCCOS-sponsored study found that freshwater cyanobacteria, and their toxins, produced in a compartmentalized California estuary can accumulate and enter marine waters episodically, particularly during storms and significant tidal exchange ...

Virtual Workshop Empowers Arctic Tribal Communitie...

NCCOS scientists, in collaboration with Ocean and Earth Environmental Services, conducted a virtual workshop in January to introduce members of the Norton Sound Health Corporation (NSHC) to methods and techniques ...

Algal Cyst Sampling in Alaska Advances Multi-Regio...

Sediment collection in Chiniak Bay, near Kodiak Alaska. Credit: Julie Matweyou, Alaska Sea Grant NCCOS funded partners recently completed field work in Kodiak Alaska to continue advancing a coordinated, multi-region ...

Toxic Alga Dinophysis an Emerging Threat to Human ...

Mesodinium rubrum (left cell) captured by Dinophysis cf. ovum. Modified from Mafra Jr. et al. 2016. The toxic dinoflagellate alga Dinophysis threatens human health and coastal economies through the production ...

The influence of anthropogenic nitrogen loading and meteorological conditions on the dynamics and toxicity of Alexandrium fundyense blooms in a New York (USA) estuary

The goal of this two-year study was to explore the role of nutrients and climatic conditions in promoting reoccurring Alexandrium fundyense blooms in the Northport-Huntington Bay complex, NY, USA. A bloom in 2007 was short and small (3 weeks, 103 ...

Two new karlotoxins found in Karlodinium veneficum (strain GM2) from the East China Sea

The dinoflagellate Karlodinium veneficum is a harmful algal bloom species with a worldwide distribution. This small athecate dinoflagellate makes a family of polyketide toxins that are hemolytic, cytotoxic and ichthyotoxic. The first chemical structure for karlotoxins from East China Sea ...

Zooplankton community grazing impact on a bloom of Alexandrium fundyense in the Gulf of Maine

Shipboard grazing experiments were conducted in the Gulf of Maine and on Georges Bank during of June 2006 to estimate zooplankton community grazing impact on a natural bloom of the toxic dinoflagellate Alexandrium fundyense. Surface seawater samples containing natural populations ...
