In this study we quantify thaw slump enlargement, investigate thermokarst impacts, and map the propagation of effects through hydrological networks draining permafrost terrain.

We collected water and bug samples at 36 sites in the Stony Creek watershed in the Gwich’in Settlement Area to test if thaw slumps affect macroinvertebrates in streams.

From 2010-2014, we sampled the physical habitat and benthic invertebrates (bugs) in the Peel Plateau to assess how permafrost thaw slumps impact stream health.
