Surface hydrology is an important aspect of northern environments on account of the thermal influence of water on permafrost. In this study, we demonstrate the ability of light detection and ranging (LiDAR) to map wet terrain Read more... about High-Resolution Mapping of Wet Terrain within Discontinuous Permafrost using LiDAR Intensity
