International Permafrost Association 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 ipa-permafrost. org
International Permafrost Association 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 thermal state of permafrost under the leadership of the IPA for June 2010 ipa-permafrost. org
International Permafrost Association 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) ipa-permafrost. org
