Modelled basal melt rate underneath the Antarctic Lambert–Amery glacial system
This is the modelled basal melt rates in six experiments using different geothermal heat flux (GHF) maps as forcing for an offline coupling between a forward model and an inverse model. The forward model consists of a thermomechanical steady state model using an improved shallow ice approximation in...

The inverse model is solved using 3D full Stokes model. The six GHF maps are from Martos et al. (2017), Shen et al. (2020), An et al.
