Wood from trees that fell into Arctic-draining rivers thousands of years ago is giving scientists a detailed look at how Arctic Ocean circulation has changed over the past 12,000 years. In a new study, researchers used nearly 1,000 pieces of driftwood collected from Arctic shorelines since the 1950s to track Arctic sea ice extent and ocean circulation since the start of the Holocene.

In his job as a university machinist, Dale Pomraning has built and fixed earthquake detectors and aurora rockets. But recently he worked on his first object that was once part of a living creature.

Life returning to island destroyed by eruption

Nine years after it erupted, Kasatochi Island is just beginning to resemble its neighbors.

Kasatochi is a speck in the middle of the Aleutian chain between Dutch Harbor and Adak, about 75 miles east of the latter. The volcanic island had no modern history of erupting until August 2008. In a few days that summer, the island changed from the lush green home of a quarter million seabirds to a gray pile of ash.
