U.S. Geological Survey's Borehole Temperature Logs from Arctic Alaska, pre-1989


This zipped file contains the borehole temperature measurements acquired in permafrost regions of arctic Alaska between 1950 and 1988 by the U.S. Geological Survey. A large number of the 87 sites (boreholes) represented in this dataset are deep enough to penetrate the base of permafrost. Max Brewer was the principal investigator prior to 1956. Art Lachenbruch then led the Alaska effort through 1989. Data collection methods changed considerably during this time period. The methods utilized by the U.S. Geological Survey to measure subsurface temperatures have evolved considerably over the years. Although some of the early measurements were obtained using thermistor strings frozen into permafrost, the vast majority of the measurements [...]
