Wilkes Land Expedition

By drilling into deep ocean sediments along Antarctica, scientists hope to uncover the earth’s climate history from a time when Antarctica was largely ice-free, and to investigate its transition to the glacier-covered continent we know today. Investigating this history will help lead to a better understanding of the climate changes we’re experiencing in the present day. {Read More »}

The Mystery of the Exploding Cores

ABOARD THE JOIDES RESOLUTION, ON THE BERING SEA-- Why do some cores explode? One of the problems we’ve had on this expedition is that some of the cores are a bit gaseous. As you go to the sea floor and below it, the pressure from the water above is tremendous... {Read More »}
