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 […]

Planet Imagery Helps Find that Rapid Sediment Re-Deposition May Limit Carbon Release during Catastrophic Thermokast Lake Drainage


Arctic permafrost is the frozen ground in and around the arctic circle which holds mass amounts of soil organic carbon. But due to warming global temperatures, Arctic permafrost is beginning to unfreeze and degrade, releasing stored greenhouse gas emissions including carbon dioxide and methane into the atmosphere. Within this landscape, thawing land, […]

Extreme Flow Velocities and Formation of a Dammed Lake


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 […]
