An international team of Oregon State University scientists, documentary filmmakers and environmental advocates has uncovered an apparent illegal trade in whalemeat, linking whales killed in Japan’s controversial scientific whaling program to sushi restaurants in Seoul, South Korea, and Los Angeles, Calif. 

A crew from the Pinniped Ecology Applied Research Laboratory (PEARL) with OSU's Marine Mammal Institute is helping the North Coast Marine Mammal Center (http://www.northcoastmmc.org/index.php) track a young female Steller sea lion who was released from the rehabilitation facility in Crescent City, CA on Saturday, March 27. Markus Horning and interns Julia Hager, Stephen Meck and Jennifer Olson glued a satellite transmitter to the fur on the animals' head using 5-minute epoxy. The transmitter allows researchers to track the sea lion's location on a daily basis. The device is expected to fall off by the annual molt in August.

This is the first time a...

A sub-adult Steller sea lion was successfully disentangled from a trawl net at Sea Lion Caves on Thursday March18. Click HERE for details.

For several months this past fall and winter, thousands of California sea lions (Zalophus californianus) assembled on and just offshore of a remote beach just to the south of Heceta Head on the central Oregon coast. It is unknown specifically what attracted so many of these animals to this site, although it is clear that enormous amounts of prey fish (possibly herring, squid, hake, sardine or anchovies) must have been available to support such huge numbers of sea lions. This area is also home to several hundred Steller sea lions (Eumetopias jubatus), which use nearby Sea Lion Caves as a regular haul out.

On Thursday, April 9, 2009, a fresh dead adult female gray whale (Eschrichtius robustus) was found on the beach at Washburn State Park, just north of Heceta Head.  She was extremely emaciated, and there was no evident trauma to the body. Her posture, lying belly-down flat on the sand, suggests that she died on the beach or in shallow water soon before she was reported to the stranding network. We suspect the immediate cause of death was starvation.

A sea otter (Enhydra lutris) has been sighted and photographed recently in Depoe Bay. This is the first confirmed sighting (with photographs) of a sea otter on the Central coast in many years. Although we frequently receive reports of sightings of otters on the coast, most of these are in fact river otters  (Lontra canadensis), a much more common species that lives primarily in fresh water habitats but frequently ventures into the marine environment as well.

It appears that this animal is a wanderer from either California or Washington waters. Whether or not it remains in...

"It's exciting evidence for a previously unrecognised species within the ancient lineage of Amazon river dolphins," says Scott Baker of Oregon State University in Newport. "Yet it's already rare, and its habitat is now fragmented by dams."

NOAA ship Gordon Gunter departed July 1st to continue its mission to evaluate the effects of the Deepwater Horizon BP oil spill on whales and dolphins in the Gulf of Mexico, including the endangered sperm whale. This project includes leading researchers from Cornell University, Oregon State University, and Scripps Institution of Oceanography, who will work with NOAA scientists to monitor the distributions and movements of whales over the next several months.
