The WISSARD project is composed of three interrelated sets of grants: LISSARD (Tulaczyk C-521), RAGES (Powell C-522) and GBASE (Priscu C-523). These projects are connected scientifically through common interest in coupled fluxes of ice, nutrients and water, subglacial sediments and by the common need to characterize and quantify physical, chemical, and biological processes operating subglacially. The research will focus on the lower portion of Whillans Ice Stream, where two hydrologically connected subglacial environments that lie within close geographical proximity can be accessed: Subglacial Lake Whillans and wet subglacial sediments, including the grounding-zone wedge. The GBASE component will address metabolic and phylogenetic diversity and associated biogeochemical transformations in subglacial lake and grounding zone environments.
Field Season Overview:
This year the WISSARD field season consists of a build phase from Winfly through mid-December, a test phase at the old ANDRILL MIS site (mid-December), a traverse phase through early January, a field phase at Whillans Ice Plain and SLW-Deep (Subglacial Lake Whillans) through early February, and a return traverse through end of February.
Twelve GBASE participants will deploy in mid-November and make day trips to the ADNRILL McMurdo Ice Shelf (MIS) to conduct drill tests through December. In early January the drill and labs will be traversed to Subglacial Lake Whillans (SLW). Fixed-wing aircraft will fly personnel and camp gear to the base camp at SLW. Moving samples and personnel between locations will require an estimated three fixed wing flights per week between SLW and McMurdo. Crary lab support will be required throughout the season until mid-February.
