The data contains the snow geophysical property data collected from both sea ice and lake ice during the Churchill Freeze-up Campaign (December, 2021).

The snow geophysical properties include:

  • snow salinity
  • bulk-density
  • temperature profiles.

The associated snow depth data can be found here.

The associated KuKa transect data can be found here.
