Abstract

Analysis of borehole temperatures in ice sheets can improve the accuracy of isotopic paleothermometry by making possible independent calibrations of isotope-temperature relations. Here we present a preliminary calibration of the δ¹⁸O paleothermometer for central Greenland. A numerical thermal model converts isotope-derived surface-temperature histories to temperature-depth profiles. Comparison with measured borehole temperatures allows calibration of the paleothermometer using formal inverse techniques.
