Simulating meltwater oxygen isotopes as a proxy for assessing geothermal heat flow in Greenland

Geothermal heat flow is an important control on the dynamics of glaciers and ice sheets. In Greenland however, the exact magnitude and distribution of geothermal heat flow under the ice sheet is largely unknown as only few direct measurements exist at the locations of the deep ice cores. For this reason, several studies have attempted to constrain geothermal heat flow under the ice sheet through various statistical, geophysical, and ice-dynamical modelling efforts. However, many of the different
