Scientists have found evidence in a chunk of bedrock drilled from nearly two miles below the summit of the Greenland ice sheet that the sheet nearly disappeared for an extended time in the last million years or so.

Sean Solomon, director of Columbia University's Lamont-Doherty Earth Observatory, has been leading NASA’s MESSENGER mission to Mercury for the last four years. MESSENGER is the first spacecraft to orbit Mercury.

Three Columbia professors have been named members of the National Academy of Sciences (NAS). Election to NAS, in recognition of "distinguished and continuing achievements in original research," is considered one of the highest honors a scientist or engineer can receive.

As a scientist, Sean Solomon has studied Mercury, Venus and Mars. Now he heads Columbia’s Lamont-Doherty Earth Observatory, whose researchers study planet Earth, from its deepest ocean to its highest peak.

The Lamont-Doherty Core Repository holds one of the world’s most unique and important collections of scientific samples from the deep sea—approximately 72,000 meters of sediment cores from every major ocean and sea.
