These data contain temperature observation made between July 2014 and July 2017 in three boreholes drilled 2 km from the calving front of Bowdoin Glacier (Kangerluarsuup Sermia) in northwestern Greenland.

Negative depths imply that sensors are located on the glacier surface. Sensor depths higher than the borehole depths imply that cables are not fully stretched. The data can be read by e.g. Pandas using: pd.read_csv(filename, parse_dates=True, index_col='date') Changelog: Version 1: Initial version.
