| Summary: | This work coordinates data collection using standard equipment and protocols at the Alaskan and Russian borehole sites. These borehole temperature data sets provide the baseline to reconstruct past surface temperatures, to assess the future rates of change in near-surface permafrost temperatures and permafrost boundaries, and to provide spatial data for validation of climate scenario models and temperature reanalysis approaches. This represents the US contribution to the ongoing activities of Global Terrestrial Network for Permafrost that obtains temperatures in a large number of globally distributed boreholes in order to provide a snapshot of permafrost temperatures in both time and space.
