Scientists caution against exploitation of deep ocean

The world’s oceans are vast and deep, yet technology and the quest for extracting resources from previously unreachable depths is beginning to put the deep seas on the cusp of peril.

Synchronization of North Atlantic, North Pacific preceded abrupt warming, end of ice age

A study by OSU researchers suggests that synchronization of climate patterns in the North Pacific and North Atlantic oceans may be the early warning sign for a climate change "tipping point."

15-year analysis of blue whale range off California finds conflict with shipping lanes

A 15-year analysis of satellite-tagged blue whales off the West Coast found that their favored feeding areas are bisected by heavily used shipping lanes, increasing the threat of injury and mortality.

SAR11, oceans' most abundant organism, has ability to create methane

A new study by researchers at Oregon State University demonstrates the ability of some strains of the oceans’ most abundant organism – SAR11 – to generate methane.

Study links Greenland ice sheet collapse, sea level rise 400,000 years ago

A new study suggests that a warming period more than 400,000 years ago pushed the Greenland ice sheet past its stability threshold, raising global sea levels some 4-6 meters.

Sea star disease epidemic surges in Oregon, local extinctions expected

In the past two weeks an epidemic of sea star wasting syndrome has exploded in Oregon, creating a significant threat to marine intertidal ecosystems.

Antarctic Ice Sheet unstable at end of last ice age

The Antarctic Ice Sheet began melting about 5,000 years earlier than previously thought coming out of the last ice age – and that shrinkage of the vast ice sheet accelerated during eight episodes, causing rapid sea level rise.

Study finds wild coho may seek genetic diversity in mate choice

New research suggests that wild coho salmon that choose mates with disease-resistant genes different from their own are more likely to produce greater numbers of adult offspring returning to the river.

Public urged to refrain from approaching seal pups

Oregon State University researchers are encouraging the public to refrain from approaching or "rescuing" seal pups on Northwest beaches this spring.

Humpback whale populations more distinct than previously thought

A new study concludes that humpback whales in three different ocean basins are distinct from one another, evolved independently and should be considered separate subspecies.
