The influence of water percolation through crevasses on the thermal regime of Himalayan mountain glaciers
2019
The Cryosphere Discussions
<p><strong>Abstract.</strong> In cold and arid climate, small glaciers with cold accumulation zone are often thought to be entirely cold based. However, Ground Penetrating Radar (GPR) measurements on Rikha Samba Glacier in the Nepal Himalaya reveal a large amount of temperate ice that seems to be influenced by the presence of crevassed areas. We used a coupled thermo-mechanical model forced by a firn model accounting for firn heating to interpret the observed thermal regime. We show that the
