Borehole electric log from the southern sector of Larsen C Ice Shelf, Antarctic Peninsula, December 2022

This is an electric log of a borehole drilled by hot water to 120 m (Site 1) on Larsen C Ice Shelf, Antarctic Peninsula. The borehole was drilled in December 2022 to investigate the internal properties of a suture zone (Site 1) and a meteoric ice band (Site 2) of an ice shelf, as part of the NERC-funded RiPIce (Rift Propagation for Ice sheet models) research project.

NERC standard grant NE/T008016/1.

The dataset is an electric log from a borehole drilled to 120 m (Site 1) on Larsen C Ice Shelf, Antarctica, in December 2022. It was acquired using a slim-hole electric borehole probe manufactured by Robertson Geologging Ltd, which is comprised of a source electrode that emits a low-frequency bi-directional electric current. Boreholes were logged whilst the electric probe was travelling up the borehole.

Logs were acquired using Robertson Geologging electric probe, mini winch and Micrologger II.

Data are unaltered from those logged in the field. Due to the field site location on an ice shelf, the voltage reference fish was submerged in the ice surface around 5 m from the winch and 15 m from the borehole. Missing data are presented as -999.5.
