In icy environments, mountain lakes can be dammed not by just rock, but by long standing ice formations. But with the ongoing retreat of glaciers and icecaps around the […]

Extreme Flow Velocities and Formation of a Dammed Lake

Paper

Jakob Steiner and team use digital elevation models and Landsat imagery in combination with high resolution Planet data to quantify surface elevation changes and flow velocities during a glacial surge of the Khurdopin Glacier. They conclude that the high frequency of Planet imagery is useful to capture peak surge velocities that are […]
