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 […]

Massive Seabird Mortality Event in Oregon Linked to Harmful Algal Bloom – NCCOS and Partners Respond

In late October 2009, NOAA, state and university researchers in Oregon joined an ongoing regional effort to respond to a major seabird mortality and stranding event in the region. Thousands of seabirds appear to have been impacted by a widespread bloom of the algal species Akashiwo sanguinea. The species, believed to be non-toxic, produces soap-like foam that removes […]

Sea Lion Sickness: usoceangov Ocean Today kiosk video

Sea lions are ordinarily playful mammals…but toxic blooms of algae are making these critters sick. Learn how NOAA and its partners are studying sea lions to better understand how algae can cause illness in other mammals, including humans. “Sea Lion Sickness” is just one of many exciting videos on The Ocean Today Kiosk. For full […]
