Machine learning identifies links between world’s oceans

MIT News – Oceanographers studying the physics of the global ocean have long found themselves facing a conundrum: Fluid dynamical balances can vary greatly from point to point, rendering it difficult to make global generalizations. Factors like the wind, local topography, and meteorological exchanges make it difficult to compare one area to another. To add to the complexity, one would Read More…

Remotely Operated Vehicle Gives Scientists an Underwater View into…

CDFW – Marine scientists from the California Department of Fish and Wildlife (CDFW) and Marine Applied Research and Exploration (MARE) recently completed an unprecedented three-year survey of deep-water habitats off the California coast using a remotely operated vehicle (ROV). Beginning in 2014, MARE’s ROV Beagle was deployed throughout the state to survey and record the species and types Read More…

NOAA requests partnership with Fishery Management

The San Juan Journal – Citing a declining Southern resident orca population, the National Oceanic and Atmospheric Administration is requesting collaboration with the Pacific Fishery Management Council, the governing body that creates fishing season regulations from California to Washington. “We are taking many actions to conserve and recover Southern resident killer whales and Read More…

Expedition uncovers new insights into salmon migration

The expedition is the first in decades to study salmon in the high seas and has already made many exciting Read More…

A California battle over swordfish — and gill nets

Capitol Weekly – Conservationists are pushing a $1 million effort this summer to change the way swordfish are caught off the California coast by phasing out the use of gill nets. They are the mile-long nylon nets used to catch swordfish but that also ensnare other species, causing conservation organizations to seek an end to their use. Commercial fishermen can use gill nets now, with a Read More…

Salmon-research team on Russian trawler has low catch

Times Colonist – The Russian trawler that carried an international team of scientists on a month-long expedition in the Gulf of Alaska to investigate how Pacific salmon survive in the high seas has returned to Vancouver. Expedition organizer Richard Beamish, emeritus scientist at the Pacific Biological Institute in Nanaimo, said he was surprised that catches of salmon were lower than he Read More…

Why Restaurant Demand For Smaller Fish Fillets Is Bad News For Oceans

NPR – Bigger isn't necessarily better when it comes to catching, selling and eating fish. For certain snappers, in fact, a market preference for plate-size whole fillets is driving fishermen to target smaller fish. For some wild fish populations, this is a recipe for collapse. "The preferred size of a fillet in the U.S. market corresponds to juvenile fish that haven't had a chance to Read More…

Pacific snake eel rescued hundreds of miles north of home

Chinook Observer – Good Samaritans on Thursday afternoon rescued an unusual semi-tropical Pacific snake eel from Long Beach sands a mile south of Cranberry beach approach. Personnel from Seaside Aquarium responded to the scene and are trying to nurse the chilly eel back to health. "Being part of the Southern Washington/Northern Oregon Marine Mammal Stranding Network, we are used to Read More…

Local Scientists Continue Studying Rare Hoodwinker Sunfish

Edhat – Sometimes an opportunity shows up on your doorstep and you have to stop what you’re doing to take advantage of it. That’s what happened to the folks in Armand Kuris’ parasitology lab when a hoodwinker sunfish washed ashore near UC Santa Barbara February 19. “We always interrupt whatever we’re doing when some adventure comes up,” said Kuris, a professor of zoology in Read More…

The Secret Lives of Salmon: Where are all the pinks?

Vancouver Sun – Scientific tests performed by the Russian research vessel Kaganovsky were expected to harvest an abundance of pink salmon, which are more numerous than the other Pacific salmon species combined. That hasn’t happened. With nearly 60 test fisheries complete across a wide swath of the Pacific Ocean between Haida Gwaii and the Aleutian Islands, pinks represent only 10 per Read More…
