2016-2017 USAP Field Season
High-resolution heterogeneity at the base of Whillans Ice Stream and its control on ice dynamics

Supporting Stations: McMurdo Station
This project is a two-year extension of the geophysical monitoring of the Whillans Ice Stream (WIS) initiated in 2012-13 as an addition to the Whillans Ice Stream Subglacial Access Research Drilling (WISSARD) project. The research team's primary objective is investigating basal sliding of the WIS, both near and far, from regions known to be underlain by subglacial water, and to assess the role that hydrologic and mechanical properties of the ice-bed interface play in ice-stream motion.
Field Season Overview
Field team members will travel by LC-130 aircraft from McMurdo to the Whillans Ice Stream where they will establish a base tent camp for approximately six weeks, making trips by snowmobile to other tent camp locations. They will collaborate with team members from event C-533-M (Priscu) to remove all seismic equipment and to service and reposition GPS stations. The combined, five-person field team plus a mountaineer will work in three main locations: the ACT ski way/Grounding Zone (put-in location), WG (seismic array location), and WS (seismic array location).
