Andrew Christ, University of Vermont and Paul Bierman, University of Vermont In 1963, inside a covert U.S. military base in northern Greenland, a team of scientists began drilling down through the Greenland ice sheet. Piece by piece, they extracted an ice core 4 inches across and nearly a mile long. At the very end, they pulled up something else … Read More

Tas van Ommen It is just over 50 years since French scientist Claude Lorius dropped some glacier ice in his whisky and started a quest that continues today. Lorius was studying glaciers in Antarctica and wondered if the air bubbling out of some ice he had drilled that day might carry information from the past. The answer to that … Read More

How mixed-age air bubbles ‘smear’ the climate record - Infrequently Asked Questions

Victoria University’s Dr Ruzica Dadic It may be as slow as watching paint dry, but measuring how fast air bubbles move through slices of ice is far from boring. The slow sublimation of gas bubbles under a temperature gradient in ice cores tells Victoria University’s Dr Ruzica Dadic a complex story about how much we might be missing … Read More

ANZICE Part 2: Antarctic Climate Drivers - Journeys to the ice

Matthew Wood • May 24, 2010 •

To ask the question, ’How will Antarctica respond to a warmer world?’ is similar to pondering, ’What was the weather like in the United States last century?’ In both cases there are multiple layers of complexity — from persistent regional disparities to variability on a range of timescales — yet this is a question being tackled by Earth … Read More
