Glacier structure influence on Himalayan ice‐front morphology

We investigate the role of glacier structures in controlling ice-front morphology and dynamics four Himalayan lake-terminating glaciers over a 20-year period. At Imja, Trakarding, Lumdin Dang Pu glaciers, lake area was mapped between 2000 2020 using Landsat 5/7/8 Sentinel-2 imagery. Discrete flow units were identified, with (e.g., open crevasses, transverse structures, longitudinal structures) digitised finest resolution panchromatic bands each year (30, 15, or 10 m). Mapping revealed distinct pattern towards terminus that influence position are then exploited via iceberg calving events. Our structural analysis also illustrates subsurface conduits During conduit collapse, recession is enhanced, leading to along adjacent structures. Furthermore, our shows influences recession. Ice fronts ice aprons undergo slower periods than cliffs. conclude important determining morphologies at therefore, vital when assessing future positions behaviour, as well rates
