Permafrost Observatory Project - Thermal State of Permafrost (TSP)Thermal State of Permafrost Permafrost conditions underlie upwards of 25% of the Earth's land surface. Permafrost temperatures are a function of past and present climates and vary greatly depending on location. Lacking is a comprehensive set of pemafrost measurements against which to assess present and future regional and global changes. Duirng IPY, TSP researchers will obtain a "snapshot" of permafrost temperatures in hundread of borehole throughout the world.
International Permafrost Association (IPA), as its contribution to the International Polar Year (2007-2009), will obtain a
