Description
Summary:Kamb Ice Stream ceased flowing from the West Antarctic Ice Sheet into the Ross Ice Shelf approximately 150 years. Stagnation of this ice stream has been attributed to changes in the routing of subglacial water. The KambSeis experiment targets a major subglacial drainage channel that crosses the ice-sheet ice-shelf transition and enters the sub ice shelf cavity. Using four small arrays surrounding the surface expression of the subglacial channel we aim to characterise drainage of subglacial water through the channel. This channel is the focus of ongoing study with active source seismic and oversnow radar data collected in the 2015-2016 austral summer and direct access planned for 2020/2021.
