Hot rocks in a cold place: high sub-glacial heat flow in East Antarctica
Numerical models are the primary predictive tools for understanding the dynamic behaviour of the Antarctic ice sheet. However, a key boundary parameter, sub-glacial heat flow, remains poorly constrained. We show that variations in abundance and distribution of heat-producing elements within the Anta...

Numerical models are the primary predictive tools for understanding the dynamic behaviour of the Antarctic ice sheet. However, a key boundary parameter, sub-glacial heat flow, remains poorly constrained. We show that variations in abundance and distribution of heat-producing elements within the Antarctic continental crust result in greater and more variable regional sub-glacial heat flows than currently assumed in ice modelling studies. Such elevated heat flows would have a fundamental effect on ice sheet behaviour and highlight that geological controls on heat flow must be considered to obtain more accurate and refined predictions of ice mass balance and sea-level change. |
