Buried Ice in Antarctica 2012
Another Way to Connect!
Dr. Dave Marchant's graduate student, Alistair Hayden, will also be connecting with students by blogging about the expedition at this site: [Boston University Antarctica Research Group - Field Blog(http://buantarcticblog.blogspot.com/)
You can also read Jackie's journals from her expedition in 2008, also with Dr. Marchant here.
Meet the Team
Associate Professor - Jacquelyn Hams
Jacquelyn (Jackie) Hams is an Associate Professor of Earth Science at Los Angeles Valley Community College, where she teaches Physical Geology, Introduction to Oceanography, Environmental Science, and Planetary Science to many first generation college students. Ms. Hams has a scientific background in environmental and subsurface investigations in terrestrial and marine environments and experience working with Fortune 100 companies as an environmental consultant and as a petroleum geologist. Ms. Hams holds a Master's degree in Geology and enjoys sailing and outdoor photography.
Researcher - Dave Marchant
Dr. Dave Marchant has led 21 field expeditions to Antarctica. His research interests are in the fields of glacial and periglacial geomorphology, global climate change, and planetary geology. In his research, he links traditional geomorphic field observations in ice-free areas of the continent with state-of-the-art geophysical, remote sensing, and dating techniques. Dr. Marchant is currently the Director of Undergraduate Studies in Earth Sciences at Boston University.

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.
What are they Doing?
In addition to drilling for ancient ice, the team is working 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.
