MELT, TARSAN, GHC, THOR, and TIME teams will depart for McMurdo in early November 2019, and will deploy to the field between late November 2019 and January 2020.

ITGC teams plan to drill through the floating ice at the edge of the ice sheet, install instrumentation to measure the ocean, and use seismic and radar systems to map the ice thickness and the cavity beneath the ice. Teams will also collect sample sediment cores from the sub-ice seabed. A geoscience team will collect rock samples from nearby mountains to examine the past history of the ice sheet. Farther upstream, another field team will investigate the boundary between the fast-flowing ice of Thwaites Glacier and the near-stationary ice next to it.
