SC1: Antarctic Geothermal Heat Flux

SC1 Antarctic Geothermal Heat Flux

OBJECTIVES:

Support efforts to provide refined and robust estimates of geothermal heat flow in Antarctica.
Understand how geothermal heat impacts the ice sheets.
Connect Antarctic geothermal models and data to heat flow studies in other continents.
Support open access to data, models and code.
Facilitate links between ice sheet modellers, geologists. solid Earth geophysics and hydrologists .
