From: Accelerated thermokarst formation in the McMurdo Dry Valleys, Antarctica
Ice cliff thermokarst erosion (measured vertically from the 2001 surface—see SI) calculated by differencing the 2001 airborne LiDAR7 and the January 2012 terrestrial laser scan.
White dot indicates location of continuous measurement station. Solid white lines indicate infrared radiometer and sonic ranger field of view. Dashed line indicates area of erosion between initial ice/sediment deposition (Pleistocene/Holocene) and 2001. Base map is a hill-shade derived from the January 2012 TLS overlain on a hill-shade derived from 2001–2002 airborne LiDAR to extend the base map beyond the range of the ground-based scans. Arrow indicates illumination direction.
