NSF-funded team samples Antarctic lake beneath the ice sheet
Date:1/29/2013

and national planning and 3 1/2 years of project preparation by the WISSARD consortium of U.S. universities and two international contributors. There are 13 WISSARD principal investigators representing eight different U.S. institutions.

NSF, which manages the United States Antarctic Program, provided over $10 million in grants as part of NSF's International Polar Year portfolio to support the WISSARD science and development of related technologies.

The National Aeronautics and Space Administration's (NASA) Cryospheric Sciences Program, the National Oceanic and Atmospheric Administration (NOAA), and the private Gordon and Betty Moore Foundation also provided support for the project.

The interdisciplinary research team includes groups of experts in the following areas of science: life in icy environments, led by John Priscu, of Montana State University; glacial geology, led by Ross Powell, of Northern Illinois University; and glacial hydrology, led by Slawek Tulaczyk, of the University of California, Santa Cruz.

Sharing of expertise by the groups of disciplinary experts will allow the data collected to be cast in a systemic, global context.

The WISSARD team will now process the water and sediment samples they have collected in hopes of answering seminal questions related to the structure and function of subglacial microbial life, climate history and contemporary ice-sheet dynamics.

Video surveys of the lake floor and measurements of selected physical and chemical properties of the waters and sediments will allow the team to further characterize the lake and its environs.

The approach to drilling was guided by recommendations in the 2007 National Research Council-sponsored report, "Exploration of Antarctic Subglacial Aquatic Environments: Environmental and Scientific Stewardship," aimed to protect these unique environments from contamination.
