Archived PolarConnect Event: Celebrating Antarctica Day with the WISSARD project
3 December 2012
This one hour event is available in the PolarConnect Archives.
This is the first of two research seasons in Antarctica for the WISSARD (Whillans Ice Stream Subglacial Access Research Drilling) project. The goal of the WISSARD Project was to learn more about the physical, chemical, and biological aspects of the unique environments under glaciers in West Antarctica. In addition to understanding the geology and hydrology, the team studied life in extreme subglacial environments. By investigating this interrelated system, they got a better understanding of the influence of climate change on the melting of ice sheets and their contributions to sea level rise.
The WISSARD Project had three inter-related components:
The primary goal of the first field season was to test and explore the zone (grounding zone) just before the grounded ice of the Whillans Ice Stream went afloat into the Ross Ice Shelf, which is thought to be a very sensitive area in terms of ice sheet dynamics and its response to global warming. During their deployment, the team used a hot water drill to melt boreholes deep into the ice stream. After the holes were melted, they tested and deployed complex new monitoring and sampling equipment under the ice.
Learn more about the project at the official project website.
The team staged operations out of McMurdo Station, Antarctica, and then camped out and performed their research on the lower areas of the Whillans Ice Stream just before it went afloat into the Ross Ice Shelf. The ice stream is a faster flowing "stream" of ice within the West Antarctic Ice Sheet and the study site was located right at the head of the Ross Ice Shelf. McMurdo Station is located at the southern tip of Ross Island on the shore of McMurdo Sound. During the summer research season, McMurdo Station supports up to 1,200 people.
Michael LeBaron grew up "on science", learning everything from welding to soil sampling on the family farm that was a part of the University of Idaho Agricultural Experiment Station. When Mr. LeBaron began college, majoring in Geology was a natural choice, as he knew that he wanted a profession where he could work outside while continuing to learn about the world around him. He has had a variety of careers since graduating with Bachelors and Masters degrees in Geology. These have included spending many years in the oil and gas industry, working as a field geologist in Uranium and Industrial Minerals Exploration, and even a short time in the banking world. Mr. LeBaron made one last career change into teaching, opening the door for him to give back and share what he had learned over the years as a professional geologist. He teaches Earth and AP Environmental Science teacher at Lake Norman High School, bringing his various science travels and knowledge into the classroom in some pretty offbeat and unusual teaching strategies. Travels have included going to Ecuador with the North Carolina Museum of Natural History to have a firsthand look at the impacts of poverty on environmental quality, and a three-week period aboard the RV Atlantis as an observer and outreach participant in the New Millennium Observatory (NeMO) Project along the Juan de Fuca Ridge. When Mr. LeBaron is not at school or wandering around other parts of the world, he can be found traveling with his wife (also a teacher), backpacking with Boy Scout Troop 162 of Mooresville, or checking up on his two sons.
John Priscu is a professor in the Department of Land Resources and Environmental Sciences at Montana State University. His research interest lies in life associated with Antarctic ice and its relationship to global change and astrobiology. Dr. Priscu heads the Priscu Research Group.
Ross Powell has been a professor in the Department of Geology and Environmental Sciences at Northern Illinois University since the early 1980's. His main research interests focus on processes where glaciers and ice sheets enter the sea, and his recent research has focused on Alaskan and Antarctic glacimarine processes and paleoclimate history involving underwater remotely-operated vehicles (ROV's) among other scientific tools. He has played a lead role in the [ANDRILL](http://www.andrill.org/static/index.html) (Antarctic geological Drilling) Program and the [WISSARD](http://www.wissard.org/) program, collecting sediment cores for the first time from a subglacial lake in Antarctica—Lake Whillans. He has mentored teachers in polar field research through the Cape Roberts and ANDRILL programs in Antarctica and the Svalbard REU program in the Arctic. He is also periodically a guest lecturer at the University Center ([UNIS](http://www.unis.no/)) on Svalbard.
