Several lake ice projects are underway, with the field sites set up on Cornwallis and Bathurst Islands (Nunavut). Most of the projects use field data in combination with either modelling or satellite data (or both). Three lakes are instrumented with trail cameras to capture the ice and snow conditions throughout the winter, and one lake is instrumented with an ice thickness sensor to measure the ice thickness all season. We use mainly Reconxy trail cameras as they keep working almost all the way down to -40°C, but we have also used StealthCam (these work down to -20°C) and are trying a SpyPoint this coming season (should work down to -30°C). Here are a few images from the last few years (please note the temperature stamp is not accurate).

Oops! The camera rotated after some stormy looking weather, but look at the great sunset colours we captured at 2pm!
