Accelerated mobilization of organic carbon from retrogressive thaw slumps on the northern Taymyr Peninsula ...
With climate change, Arctic hillslopes above ice-rich permafrost are vulnerable to enhanced mass wasting and organic carbon mobilization. In this study we use TanDEM-X-derived (TerraSAR-X add-on for Digital Elevation Measurement; synthetic-aperture radar) digital elevation models to document an appr...
