Risk of Toxic Shellfish on West Coast Increases with Water Temperature

High levels of domoic acid, a shellfish toxin, are correlated with warmer ocean temperatures offshore of Oregon and Washington. NCCOS-supported research team led by scientists from Oregon State University found an association between domoic acid levels in shellfish and climate-scale warm ocean conditions that gives a unique, large-scale perspective relative to previous work. The strong […]

2016 Chesapeake Bay Hypoxia Forecast is Close to Mark

As predicted by an earlier forecast sponsored by NCCOS, dissolved oxygen conditions in Maryland’s portion of the Chesapeake Bay main channel continued to be average for most of the summer of 2016. In mid-June, NCCOS issued the annual hypoxic zone forecasts for the Chesapeake Bay, predicting a close to average sized hypoxic volume for the bay […]

New Guidance for Managing HAB Impacts on California Fisheries

A newly released report from the California Ocean Science Trust highlights efforts to learn from the 2015 massive bloom of the toxin-producing marine diatom Pseudo-nitzschia that formed off the U.S. West Coast. The harmful algal bloom (HAB) impacted key fisheries, such as Dungeness crabs and razor clams, and marine mammals from California to Alaska. NOAA […]

Stakeholders Meet to Develop Harmful Algal Bloom Action Plan for Alaska

Alaska Sea Grant and the Alaska Ocean Observing System recently cosponsored a two-day workshop to develop an action plan for harmful algal bloom (HAB) monitoring, event response, outreach, and research in Alaska. NCCOS staff opened the workshop by providing a national perspective on HABs that set the stage for discussions of existing activities and identified […]

First Compendium on Deep-water Algae of Puerto Rico Published

A new taxonomic publication describes the relatively unknown algal flora of mesophotic coral ecosystems in Puerto Rico. These ecosystems are characterized by the presence of light-dependent corals and associated communities found at depths ranging from 100 to 500 feet deep. The work, published in a recent issue of Smithsonian Contributions to Botany, was supported partly by the […]

Harmful Algal Cyst Sampling Lays Groundwork for 2017 Gulf of Maine Forecast

Scientists from NOAA and Woods Hole Oceanographic Institution (WHOI) recently completed their annual harmful algal cyst sampling in the Gulf of Maine, a critical step for forecasting next year’s harmful algal blooms (HABs) of the toxic Alexandrium fundyense, commonly known as New England red tide. A. fundyense has both a vegetative stage, where cells grow and float in surface […]

Predicting the Risks of Harmful Algal Blooms for Coastal California

In California, domoic acid-producing harmful algal blooms (HABs) of the diatom Pseudo-nitzschia increasingly threaten bivalve and crab harvesters, aquaculture, and coastal ecosystems. Using a blend of models and satellite ocean color imagery, NCCOS supported the early development of the California Harmful Algae Risk Mapping (C-HARM) system that predicted the spatial likelihood of Pseudo-nitzchia blooms and levels of […]
