Permafrost Based on Changes in Type and Density of Surface Vegetation
This project will use satellite datasets in order to highlight alterations to permafrost based on changes in type and density of surface vegetation. Permafrost thaws due to climate change is a lesser studied phenomenon that has effects well beyond the Arctic ecosystems where permafrost exists. Perma...
