Getting Ready

The three weeks at Troll Station are a blur of all-important activities. Erecting the science tent on a sled that will keep the researchers out of the wind as they process snow samples and ice cores. Tens of ice core boxes need pre-labeling, to save time en route. The safety officer drills them on crevasse rescue techniques, but there's time for a birthday party for the Norwegian camp manager who is planning the menu to keep the team warm and happy en route. Hurricane force winds of more than 100 mph confine the team inside, where they test equipment. It's also time to try on Glen Liston's unique "nose mitts" - he's made one for every member of the team. Watch now to see why Atsu thinks he looks like a duck!

From Cape Town to Troll Station

US and Norwegian researchers gather in Cape Town, and relax down by the waterside before boarding plane for Troll Station. There is cargo to carefully log in and weigh, group meetings to finalize plans. The 8 hour flight to Antarctica is a time to catch up on sleep. Arriving at Troll, a sign reads "Hot Dogs", but it's just a long-running joke about the two nations preferences in food. The members of the traverse know their adventure is now truly beginning.

Deciphering the secrets of past climate hidden in ice cores depends on the technical skills and ingenuity under pressure of drillers from ICDS, the University of Wisconsin-Madison's Ice Coring and Drilling Services. In this high-spirited video, ICDS staffers Lou, Mike and Jay explain why they enjoy the life of drillers, braving extreme cold in some of the remotest regions of the globe. Mike says drilling requires both science and art, and why he keeps his hand on the cable even when it's minus 20! Lou talks about feeling connected to the equipment in order to keep it running properly, and Jay explains the satisfaction of having fun amidst beautiful scenery, and helping obtain good data for the researchers.

In May and June 2007, Mary Albert (CRREL) and Jeff Severinghaus (Scripps) led a team of 9 researchers and 3 drillers in a 3-week project to drill down through nearly 125 meters of "firn" and ice close to NSF's Summit Station, Greenland. "Firn" is multi-year snow before it's transformed into solid ice through the pressure of layer upon layer of new snow each successive year. Understanding the physical structure of the firn and the gases trapped in it, is essential to properly interpreting the ice core record, and understanding what cores reveal about Earth's past climate. As Jeff Severinghaus says, with a more accurate understanding of snow, firn and ice you can take climate data from ice cores "to the bank" - such as the fact that sometimes Earth's climate can jump 18 degrees F in just a decade - and make more accurate predictions of the future.
