When you think of an Ice Age what do you imagine? Perhaps you think of a scene of the Earth covered in ice, with mammoths and other types of megafauna roaming the land? This image is representative of the Pleistocene Epoch, a period in geologic time ranging from approximately 2.5 million to 12,000 years ago.

Since drilling operations began on June 4th, we started looking at sediment samples recovered from approximately 4,000 m water depth in the Gulf of Alaska. After almost two weeks of drilling, we have recovered several hundred meters of sediment, which will be used to reconstruct the environmental conditions of the northeastern Pacific and the adjacent land during the last 4 million years.

The Earth’s climate has varied drastically throughout geologic time. It’s hard to imagine that global climate can swing from being completely ice-free, as it was approximately 56 million years ago during the Paleocene-Eocene Thermal Maximum, to an Ice Age in a relatively short (geologically speaking) time frame.
