Heidi Roop grew up exploring the formerly glaciated landscape of Wisconsin, and today continues her love for studying glaciers and climate variability through research in Antarctica and alpine regions around the world. Spending the austral summer of 2010-2011 in Antarctica, it will be her second season working as a part of the West Antarctic Ice Sheet (WAIS) Divide project. When she is not in Antarctica, she works throughout the Sierra Nevada studying climate variability and hydrology for the United States Geological Survey.

Bruce Vaughn is the Co-Founder and Manager of the Stable Isotope Lab at the Institute of Arctic and Alpine Research (INSTAAR) (http://instaar.colorado.edu/) at the University of Colorado. The Stable Isotope Lab is devoted to studying biogeochemical processes that control environmental change on human timescales, and works to develop new techniques for measuring environmental stable isotopes. A Field Leader for the project, Mr. Vaughn has extensive research experience worldwide, including: Greenland, Antarctica, equatorial Pacific, Alaska, Ecuador, and the Cascades and Rocky Mountains.

A PhD candidate at Scripps Institution of Oceanography in La Jolla, CA, Anais Orsi studies the history of climate by analyzing gases in air bubbles trapped in ice cores. She has been involved with WAIS-divide for three years. When she is not in Antarctica, she melts ice samples in her lab to release the gases, to learn about West Antarctic climate during the last 1,000 years.

January 31, 2010 Jan 31st: End of the Season

It is hard to believe but I am already home! I arrived home sooner than I thought due to a rapid sequence of unanticipated flights! I am certainly exhausted after the long journey! The WAIS camp closed down more quickly than we thought and I left WAIS only to find myself on a plane back to...

January 25, 2010 Jan. 25th Last Day of Drilling

On January 25th we finished drilling! The final depth of the ice collected was 2561.57m! We collected over 1,000m of ice this season and are hopefully on track to finish drilling next year. Replicate coring will hopefully follow in the 2011-2012 season. It is hard to believe that the season is...

January 20, 2010 [Video] WAIS Work Commute

We have one of the best and coldest commutes to work out here at WAIS. WE often take snow machines to and from the drill arch to camp around meal times and when we are moving lots of people and cargo around. This video is a little summary of that work commute on a snow machine. It is a short...

Project Information

West Antarctic Ice Sheet (WAIS) Divide Ice Core Drilling Project
West Antarctic Ice Sheet (WAIS) Divide, Antarctica
9 November 2009
1 February 2010

Where are They?

The research team will be at the West Antarctic Ice Sheet (WAIS) drill site, in western Antarctica. The WAIS divide sits on top of 3,485 meters of ice, thicker than 9 Empire State Buildings stacked on top of one another! The WAIS is classified as a marine-based ice sheet, meaning that its bed lies well below sea level and its edges flow into floating ice shelves. The WAIS is bounded by the Ross Ice Shelf, the Ronne Ice Shelf, and outlet glaciers that drain into the Amundsen Sea.

What are they Doing?

Using a large hollow drill, the WAIS Divide Ice Core Drilling team aims to collect a 3,500-meter-long ice core, or sample of ice, from the West Antarctic Ice Sheet. Because of the weight of the overlying snowpack, snow that falls and accumulates on ice sheets re-crystallizes and forms annual layers over time. The ice core recovered during the project will have annual resolution, or distinct yearly markings, for the past 40,000 years!

In ice sheets, the compression of snow traps small bubbles of air in the layers of ice. By measuring concentrations of greenhouse gasses and non-greenhouse gasses and their isotopes trapped within bubbles in the ice, the team aims to develop climate records dating back to 100,000 years before present.

This ice core will provide the first Southern Hemisphere climate and greenhouse gas records of comparable time, resolution, and duration to ice cores previously recovered in Greenland. The ice core will enable scientists to make detailed comparisons of greenhouse gas concentrations and environmental conditions between the Northern and Southern hemispheres with a greater level of detail than previously possible. The biology of the ice collected will also be investigated.

Learn more about this process through a very interesting 20-minute video!
