"If the permafrost in Russia completely melts, it could completely transform the weather patterns on the planet, in some cases in very dangerous ways" Interview to ITAR-Tass, July 5, 2009
Monitoring Polar Permafrost • Observed Parameters • Temperatures in boreholes, near-surface temperatures in the region (Thermal State of Permafrost, TSP) • Active Layer Thickness (Circumpolar Active Layer Monitoring, CALM)
Active layer measurements on CRREL plots starting in the 1960s and resumed in 1991. Data are from 1000 x 1000 m CALM grid on Barrow Environmental Observatory, Alaska. Supported by U.S. National Science Foundation, project #OPP-0352958.

Achievements and Challenges • New and re-activated boreholes and active layer measurements during the IPY • Pilot real-time ISO-compliant temperature database (NORPERM) • Standardization of methodologies and metadata format • Coordination largely based on the internal IPA structure, with limited institutional support • Data delivery limited to regional initiatives
Future Strategy / Recommendations • GTN-P will devise a new strategy and action plan to address the growing dichotomy between its global reach and its current management capacity • GTN-P will provide a snapshot on the thermal state of permafrost under the leadership of the IPA for June 2010
Questions to GTOS SC & Actions • GTOS SC to help identify the institutional partners with the capacity and expertise to host and support GTN-P’s central management. • Cooperation with GCW on potential synergies between GTN-P and the upcoming Global Permafrost Watch (GPW)
