The 2022 NSERC PermafrostNet AGM and Yellowknife Geoscience Forum were held in Yellowknife between the 14th and 17th of November 2022.
The 2022 AGM was an in-person meeting hosted in conjunction with the 50th Yellowknife Geoscience forum. The AGM focused on the needs of partners, the progress of the network projects and future activities and in the evening the network hosted an Open House for the public to find out more about the thawing permafrost and meet the researchers studying it.
The Geoscience forum included two days of permafrost talks and posters, including two permafrost specific technical sessions: Changing Permafrost Landscapes, and Permafrost Monitoring Networks co-chaired by network members, as well as “Soapbox Talks” a scheduled 3-5 minute oral presentation by students who were presenting a poster. Soapbox talks were given with the poster as a single presentation slide projected on the screen.
