A little zoom, enhance on some cool Permafrost landforms (nets) on Devon Island from Mavic 3E imagery. The borders of the polygons are wetter and so stuff grows there making them pop in the photos.

The disturbance from wild 🔥🔥 changes the surface energy balance and leads to permafrost thaw. Here is some real data visualised of one year of thawing and subsidence from a peatland site near Yellowknife, Northwest Territories, burned in the 2023 fires. Lateral thaw > top down

A fox family was hanging out outside our hotel in Yellowknife. I resisted the urge to pet them (barely). 🦊💛

Goodnight from Devon Island, Nunavut. Here’s a video from Cape Ricketts on the south coast. Very windy today! We hiked 15km, resurveyed a bunch of cairns last surveyed by GSC bout 20 years ago, and gathered lots of lidar drone data. Now sleepy after amazing brisket dinner, and cake!
