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.
These data are part of the NERC-funded MIDAS (''Impact of surface melt and ponding on ice shelf dynamics and stability'') research project, with grant references NE/L006707/1 and NE/L005409/1. Borehole density and temperature profiles are also available, as are other MIDAS datasets.

Images are unaltered from those logged in the field. The OPTV technique is described by Hubbard and others (2008).
Most, but not all, OPTV logs are at a resolution of 360 pixels around the borehole and at a vertical resolution of 1 mm.
