What Are They Doing?
In addition to drilling for ancient ice, the team worked in the Dry Valleys to seek a better understanding of surface processes that play a critical role in maintaining and/or modifying buried glacier ice. Despite their age and potential to register long-term climate change, there has been surprisingly little research on the geologic and geomorphologic processes that both preserve and modify debris-covered glaciers in Antarctica. In addition, the cold polar desert of the Dry Valleys is one of the most Mars-like climatic environments and landscapes on Earth, serving as a proxy for very ancient ice buried on Mars and providing insight into Martian history and the potential for life on Mars.
Where Are They?
The McMurdo Dry Valleys are located on the western coast of McMurdo Sound and form the largest relatively ice-free area on the Antarctic continent. The perennially ice-covered lakes, frozen alpine glaciers, and extensive areas of exposed soil and permafrost within the McMurdo Dry Valleys are subject to low temperatures, limited snowfall, and salt accumulation.
