Borehole optical televiewer (OPTV) logs from the northern sector of Larsen C Ice Shelf, Antarctica

These are digital optical televiewer (OPTV) logs of five boreholes drilled by hot water to ~100 m depth in Larsen C Ice Shelf, Antarctica. Boreholes were drilled in austral summers of 2014 and 2015 in order to investigate the internal properties of the ice shelf, and specifically the influence of surface melting and melt pond formation on those properties, as part of the NERC-funded MIDAS ("Impact of surface melt and ponding on ice shelf dynamics and stability") research project. These data are part of a larger project. Borehole density and temperature profiles are also available, as are more general data including surface radar profiles, flow-line model code, AWS data and SMB data.
