These data consist of fully processed borehole temperature logs acquired by the U.S. Geological Survey from the 24-element DOI/GTN-P Deep Borehole Array in arctic Alaska beginning in 1973. Processing steps include: application of the appropriate calibration factors, noise removal, and deconvolution of the signal to correct for the thermal memory of the temperature sensor as it was lowered downhole at a constant rate. Pre-1984 logs were acquired at fixed depth intervals using the stop-and-go logging method and hence did not require deconvolution. The logs in this dataset represent the true temperatures in the wellbores and surrounding rocks at the time of the measurements; they have not been corrected for the thermal disturbance caused by circulating fluids and other processes while drilling the wells. A complete description of the data collection program, instruments used, data processing steps, and a graphical presentation of the data is provided in Clow, G.D., 2014: Earth System Science Data, 6, 201-218, doi:10.5194/essd-6-201-2014.
