Early results

Although our final results won’t begin to be published until early next year, our team met in May to review all the data we had collected so far.

We had drilled several types of cores. Our initial pilot cores, taken in 1998 and 2003, provided proof of concept, demonstrating the importance of these cores as a climate record, as they contain climate data that extend back in time 300,000 years — roughly three times longer back in time than the oldest portions of the Greenland ice core records.

The thrill to drill in the chill

Nearly 3.6 million years ago, a large asteroid slammed into Earth in what is today northeastern Russia. Within minutes, the impact formed an 18-kilometer-wide hole in the ground that then filled with water.

Seal missing link found in the Arctic

A newly discovered web-footed mammal may be a “missing link” between land-based and marine pinnipeds, a group that includes seals, walruses and sea lions. The find, occurring on the 150th anniversary of Charles Darwin’s "On the Origin of Species," may shed new light on the land-to-sea animal evolutionary theory.

Arctic soils retain more carbon

Don’t look now, but a slumbering beast rests in the north. It’s not news that the North American Arctic, where trees dare not grow, contains immense amounts of organic carbon in its soils. But according to a new study, past estimates of organic carbon concentrations in Arctic soils are too low — and that has some scientists worried about vast amounts of carbon being released as temperatures warm.
