NOAA-Funded Workshop Addresses State of Harmful Algal Bloom Sensors

In late January 2017, NCCOS scientists Marc Suddleson and Greg Doucette joined U.S. and international colleagues at an Alliance for Coastal Technologies workshop to evaluate the state of harmful algal bloom (HAB) sensor technologies. Attendees focused on ways to expedite sensor transition to commercialization and the potential for integrating sensors with coastal monitoring, ocean observing, and […]

New Guidance for Standardized Deep-Sea Observations

A new NCCOS report analyzes the application of the Coastal and Marine Ecological Classification Standard (CMECS) in Deep-Sea benthic surveys in the Northeast Pacific. The CMECS is intended to unify habitat classification efforts, in order to allow for broader integration and comparison of data. Habitat classification is important because it helps to identify deep-sea corals, hydrocarbon seep communities, […]

2017 California Estuary Harmful Algal Bloom Monitoring Begins

Last month, NCCOS-sponsored scientists began harmful algae and algal toxin monitoring in California estuaries. The monitoring is part of a collaborative NOAA–state response to recent research showing that a mixture of marine and freshwater toxins can reside in estuarine waters. The research found that this toxic “cocktail” could also be fatal to shellfish, sea otters, […]

California Mapping Initiative Identifies Priority Areas of Seafloor

Bathymetric and seafloor information is critical for decision-making in a number of marine management fields, including navigational safety, fisheries, renewable energy, oil and gas extraction, and ecological conservation. Prior to a recent effort to identify information gaps in seafloor mapping data in Southern California, only 13 percent of the region out to the Exclusive Economic Zone Line […]

Winners and Losers in the California Current under Future Ocean Acidification

A NOAA-supported study projects that Dungeness crab and some commercial finfish species living on the sea floor may decline in future years due to increased ocean acidification in the California Current. These estimates were based on computer models forecasting changes in the California Current ocean ecosystem, which includes an expected rise in summer ocean acidification […]

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. An NCCOS-supported research team led by scientists from Oregon State University, the University of Oregon, and the Oregon Department of Fish and Wildlife found an association between domoic acid levels in shellfish and climate-scale warm ocean […]

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 […]

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 […]
