Gallery Muostakh Island is a slender crescent of land in the Laptev Sea with ice-rich Yedoma permafrost. The sun has set over Muostakh Island in the central Laptev Sea. A driftwood fire on the beach provides [...] provides warmth at the end of the summer as we ready to return to civilization. Since permafrost begins to degrade as soon as it is submerged, for example as the coastline retreats, we often work close

In remote and vast Arctic areas satellite and aerial imagery provide insights into permafrost thaw processes on a regional scale which we would not gain from measurements at the surface. Remote [...] sensing component of the project, therefore, addresses the following research questions: 1. How do permafrost erosion features respond to changes in meteorological conditions? 2. What are the factors controlling
