This dataset contains direct temperature measurements taken from boreholes drilled into the Earth's crust. These measurements can provide insight about past surface temperatures. Anomalies or departures from the geothermal gradient (measurements taken from deeper layers tend to be warmer) can be used to identify significant surface temperature changes in previous eras. A majority of the borehole data at the World Data Service for Paleoclimatology are from the University of Michigan's Global Database of Borehole Temperatures and Climate Reconstructions.
