OSU researchers tagging whales off southern California

OSU researchers are tagging blue and fin whales off southern California as a follow-up to their landmark 15-year analysis on blue whale distribution published last month.

First tagging study of Antarctic minke whales shows unique feeding

Scientists for the first time have used tags to track the behavior of Antarctic minke whales and discovered that they feed in ways unique from other species.

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.

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
