Inversion of Geothermal Heat Flux under the Ice Sheet of Princess Elizabeth Land, East Antarctica

Antarctic geothermal heat flux is a basic input variable for ice sheet dynamics simulation. It greatly affects the temperature and mechanical properties at bottom of sheet, influencing sliding, melting, internal deformation. Due to fact that Antarctica covered by thick direct measurements are very limited. This study was carried out estimate regional in continent through geophysical inversion. Princess Elizabeth Land, East one areas which we have weak understanding flux. Through latest airborne geomagnetic data, inverted Curie depth, obtaining bedrock based on one-dimensional steady-state conduction equation. The results indicated depth Land shallower than previously estimated, consequently higher. Thus, contribution subglacial melting likely greater expected this region. further provides research clues formation developed water system Land.
