Detecting Supraglacial Meltwater Drainage on the Devon Ice Cap using Kennaugh Decomposition of TerraSAR-X imagery
During the past three decades, increases in mean summer air temperature over the Canadian Arctic have resulted in a longer melt season and intensified mass loss from ice caps and glaciers, mainly via supraglacial melt and meltwater runoff. However, the processes by which meltwater is delivered to th...
