| Abstract: | To assess role of thermal contraction-crack polygons (sublimation polygons) in modulating sublimation of buried glacier ice in Antarctica, authors apply 2D numerical model using COMSOL Multiphysics that calculates rate and spatial variability of vapour diffusion through porous media. Specifically, examines vapour transport through granite drift, dry superglacial till marked with thermal contraction-crack polygons that rests on 8-million-year old glacier ice. Emphasises importance of including field-based data for drift texture, topography, and microclimate variation in modelling ice sublimation. Concludes that preservation of buried ancient ice is plausible in coldest and driest regions of Antarctica. |
