This data set contains temperature-depth profile measurements taken in 22 boreholes drilled on the West Antarctic Ice Sheet, which exhibit two distinctly different thermal states of basal ice: a warm… Read more »

This data set is comprised of four surveyed valleys focusing on the depth to ground ice in the high-elevation Quartermain Mountains in the Beacon Valley area: University Valley, Farnell Valley,… Read more »

This data set is a collection of video data of basal ice taken in a borehole on the Kamb Ice Stream in West Antarctica. Ice streams are an expression of… Read more »

This data set presents ice sheet history and dynamics on the Thwaites Glacier and Pine Island Glacier in the Amundsen Sea sector of the West Antarctic Ice Sheet.

This data set characterizes the microstructure in ice cores, in particular the microstructural locations of impurities, grain orientations, and strain gradients. The fabric of polycrystalline ice is typically described using… Read more »

This data set contains lake boundaries, volume changes, and gridded elevations for 124 active subglacial lakes beneath the Antarctic ice sheet. Lakes were identified using laser altimetry data obtained from… Read more »
