This dataset currently contains 761 ten meter borehole temperatures across Greenland and Antarctica. These measurements were taken either from individual boreholes or during traverses. This dataset is a compilation of work from many individual researchers. When using this dataset please cite both the individual researchers who provided the data as listed in the Citation field as well as this dataset. Much of this data was originally in Antarctic Ice Temperature Data (THERMAP), a National Snow and Ice Data Center (NSIDC) funded project of temperature data that is no longer available. The measurement methods include Thermohm and Wheatstone bridges, Leeds and Northrup 4735 guarded Wheatstone bridge and a 9834 null detectors, Leeds and Northrup thermohms, Thermister thermometers, Mercury-iridium thermometers, Glass-bead thermistor and a Direct Current (D.C.) Wheatstone's Bridges, and RST ThermArrays. The majority of the measurements (greater than 99%) are from Antarctica with few from Greenland, though this will be updated on an annual basis to include more measurements from both the Arctic and Antarctic. Fields of the data include Date Taken, Latitude, Longitude, Depth Taken, Borehole Temperature, Error, Delta Time, Length of Measurement, elevation, method, name, and citation.
