Research Promotes Method to Slow the Spread of Encrusting Invasive Species

Dredging channels and cleaning boat hulls or fishing gear in or near established Didemnum colonies can create fragments of these invasive organisms that survive in the water column up to four weeks, disperse long distances, and even reproduce before resettling, possibly in new areas, according to NOAA research. The article suggests that cleaning equipment on land and reducing bottom disturbance […]

New Test Identifies Low Level Toxin Exposure to Protect Human Health

A NCCOS Ecology and Oceanography of Harmful Algal Blooms (ECOHAB)-funded study at the University of Washington and the NOAA National Marine Fisheries Service laboratory in Seattle has developed a unique and convenient way to detect very low levels of exposure to the harmful algal toxin domoic acid in laboratory zebrafish and in wild California Sea lions. […]

NOAA and Partner Scientists Discover Way to Detect Low-level Exposure to Seafood Toxin in marine animals

NOAA scientists and their colleagues have discovered a biological marker in the blood of laboratory zebrafish and marine mammals that shows when they have been repeatedly exposed to low levels of domoic acid, which is potentially toxic at high levels. While little is known about how low-level exposure to domoic acid affects marine animals or […]

Pacific Northwest HAB Project Helps Predict Japanese Tsunami Debris Paths

Where, how and why harmful algal blooms occur off coastal Washington and Oregon and predicting their arrival on coastal beaches is the goal of the NCCOS sponsored harmful algal bloom (HAB) project “PNWTOX” (Pacific Northwest Toxins).   A PNWTOX model developed for HABs is being put to use to help forecast the movement of the debris field […]

Northwest Oyster Die-offs Show Ocean Acidification Has Arrived by Elizabeth Grossman: Yale Environment 360

Standing on the shores of Netarts Bay in Oregon on a sunny fall morning, it’s hard to imagine that the fate of the oysters being raised here at the Whiskey Creek Shellfish Hatchery is being determined by what came out of smokestacks and tailpipes in the 1960s and ‘70s. But this rural coastal spot and […]

Monitoring Program Expanded for HAB Event Early Warning in Oregon

NOAA-funded partners in Oregon have expanded a pilot project that protects the health of Oregonians while minimizing the economic impacts of closures of valuable state shellfisheries. The project monitors coastal waters for the abundance of toxic algae species (Pseudo-nitzschia and Alexandrium) and the algal toxin domoic acid. The Oregon Department of Fish and Wildlife (ODFW) […]

Major Accomplishments of 2010

The National Centers for Coastal Ocean Science (NCCOS) supports competitively-funded, regional, multiyear, multidisciplinary ecosystem research, modeling, and information delivery activities to improve predictions and management decisions in the coastal ocean and Great Lakes.  In 2010 NCCOS advanced understanding and developed tools for management in three major research areas: hypoxia, deep light-dependent coral reefs, and harmful […]

HAB Monitors Close Beaches in Oregon to Protect Recreational Clammers

A pilot program to monitor harmful algal species and their toxins in Oregon last week confirmed elevated domoic acid levels in razor clams, prompting the closure of popular state recreational clamming beaches from Tillamook Head to Bandon Beach (about a 240 mile stretch of Oregon’s 363 miles of coast). Domoic acid is a neurotoxin produced […]
