My master’s project examines how shrub expansion in the Arctic affects the summer thermal regime of permafrost. Using dense instrumentation on Bylot Island, Nunavut (73°N), we aim to quantify the surface energy-balance terms at two adjacent environments (moss-dominated tundra vs. shrub-dominated). The dataset will help identify, at these sites, the main mechanisms driving the increase in active-layer thickness (the upper soil layer that thaws in summer).
