NOAA’s National Ocean Service: Virtual fly-through of the Gulf of the Farallones National Marine Sanctuary

Take three minutes out of your day to watch this amazing virtual ‘fly-through’ of deep-sea areas within NOAA’s Gulf of the Farallones National Marine Sanctuary in California. (3:28 minutes) Visualizations like this one help the sanctuary’s managers protect plants and animals important to the area’s fragile habitats. Safeguarding productive places today can ensure a healthier […]

A Virtual First Look at Unexplored Seafloor – Gulf of the Farallones – OurAmazingPlanet.com

A new mapping tool has given scientists a first glimpse of an area of the seafloor just west of the San Francisco Bay and, thanks to a new animation, ordinary people can take a ride over the newfound and dramatic topography. The newly mapped ocean floor lies within the Gulf of the Farallones National Marine […]

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 […]

NCCOS Research Shows Animals in the Womb Retain Algal Toxin

California sea lions have been stranding with increasing signs of seizures due to domoic acid (DA) poisoning. Pregnant females are commonly affected and frequently lose their young after exposure to this harmful algal neurotoxin. Juveniles exhibit an epileptic disease state, even in the absence of the causative diatom Pseudo-nitzchia. Rodent models have established that low-level […]

DNA Microarray Tool Successfully Identifies Domoic Acid Toxicity in California Sea Lions

The National Centers for Coastal Ocean Science (NCCOS) has developed a DNA microarray for profiling gene expression patterns in blood to aid in clinical and population level studies of domoic acid exposure on sea lions. There is currently no straightforward way to diagnose domoic acid poisoning due to the highly variable symptoms, the fact that […]
