Pacific sleeper sharks, a slow-moving species thought of as primarily a scavenger or predator of fish, may be preying on something larger – protected Steller sea lions in the Gulf of Alaska.
Rocky assemblages known as authigenic carbonates in many oceans contain methane-eating microbes that constitute a previously unknown "sink" for this potent greenhouse gas.
Scientists are asking coastal visitors to be on the lookout for "transponders" from Japan that are being used to track ocean currents that may bring tsunami debris to our shores.
A new six-year, $21 million initiative funded by the NSF will explore the role of carbon and heat exchanges in the vast Southern Ocean – and their potential impacts on climate change.
Annual mean temperature in the Northwest has warmed by about 1.3 degrees (F) since the early 20th century – a warming trend that has been accelerating over the past 3-4 decades.
The Northwest coast looked vastly different 14,000 years ago from what scientists previously thought, and the exposed land mass may have allowed the First Americans to enter the region.
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.
A new study published in Science concludes that sunlight, not bacteria, is the key to converting organic carbon stored in Arctic tundra into carbon dioxide.
Researchers established a new breeding colony for one of the world’s most endangered seabirds – the Chinese crested tern – which had a global population of fewer than 50 birds.
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.
