To assess the role of thermal contraction-crack polygons (sublimation polygons) in modulating sublimation of buried glacier ice in Antarctica, the AA. applied a 2D numerical model using COMSOL Multiphysics that calculates the rate and spatial
. The model results show that sublimation varies with drift texture and surface topography. The importance of including field-based data for drift texture, topography and microclimate variation in modelling ice sublimation is highlighted. The results also
