PNAS Commentary: Study sheds new light on sea level rise at last ice age

A new study suggesting that the contribution of the Antarctic ice sheets to sea level rise is less than once thought has significant implications for future sea level change, according to a commentary by OSU's Peter Clark.

New study shows three abrupt pulse of CO2 during last deglaciation

A new study shows that the rise of atmospheric carbon dioxide that contributed to the end of the last ice age was characterized by three “pulses” of rapid C02 increase.

Study: Could sleeper sharks be preying on protected Steller sea lions?

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.

Scientists discover carbonate rocks are unrecognized methane sink

Rocky assemblages known as authigenic carbonates in many oceans contain methane-eating microbes that constitute a previously unknown "sink" for this potent greenhouse gas.

Anglers, beachcombers asked to watch for transponders from Japan

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.

OSU part of major grant to study Southern Ocean carbon cycle

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.

Study: Pacific Northwest shows warming trend over past century-plus

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.

Study provides new look at ancient coastline, pathway for early Americans

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 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.

Science study: Sunlight, not microbes, key to CO2 in Arctic

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.
