Abstract:
The datasets are temperature time series from fibre-optic strings installed into two boreholes on Larsen C Ice Shelf, Antarctic Peninsula. Boreholes were drilled in December 2022 to 160 m 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.

| Data Storage: | The data are structured in two comma-separated ASCII files (*.csv format), one for each borehole. The file name consists of RIPICE, the site number, and IceTemperatureData. Each file holds the data for a single borehole, with each column presenting the temperature measured at a given depth along the fibre-optic cable (labelled by depth beneath the glacier surface, in metres), and each row the date and time at which the temperature was recorded. Temperatures are in degrees Celsius. |
