The permafrost thaw action group attended the annual meeting of PermafrostNet on November 18 to represent T-MOSAiC. This NSERC network is led by Stephan Gruber and it was very nice and well-organized meeting. We had several people attending our T-MOSAiC break out session with interest about our standardized protocol to measure permafrost thaw. If you are interested in the protocol at your site, please contact the AG Chairs. Soon a great mobile app for recording data will be released.
