Thermal state of permafrost and active‐layer monitoring in the antarctic: Advances during the international polar year 2007–2009
Abstract Results obtained during the International Polar Year (IPY) on the thermal state of permafrost and the active layer in the Antarctic are presented, forming part of ANTPAS (‘Antarctic Permafrost and Soils’), which was one of the key projects developed by the International Permafrost Associati...
