State of the Antarctic: SCAR report shows continent undergoing major changes

Ice core drilling in Antarctica

Part of a typical workday during the US ITASE traverse, Mark Wumkes operates the drill while Paul Mayewski helps out in the drill pit. Susan Kaspari measures and logs the core while Lynn Peters and Carl Hess recover a fuel bundle in the background. The International Trans Antarctic Scientific Expedition (ITASE), under the leadership of Dr. Paul Mayewski, studies environmental change over the past 200 years.
