description |
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 Association and the Scientific Committee for Antarctic Research for the IPY. The number of boreholes for permafrost and active-layer monitoring was increased from 21 to 73 during the IPY, while CALM-S sites to monitor the active layer were increased from 18 to 28. Permafrost temperatures during the IPY were slightly below 0 degrees C in the South Shetlands near sea-level, showing that this area is near the climatic boundary of permafrost and has the highest sensitivity to climate change in the region. Permafrost temperatures were much lower in continental Antarctica: from the coast to the interior and with increasing elevation they ranged between -13.3 degrees C and 18.6 degrees C in Northern Victoria Land, from -17.4 degrees C to -22.5 degrees C in the McMurdo Dry Valleys, and down to -23.6 degrees C at high elevation on Mount Fleming (Ross Island). Other monitored regions in continental Antarctica also showed cold permafrost: Queen Maud Land exhibited values down to -17.8 degrees C on nunataks, while in Novolazar-evskaya (Schirmacher Oasis) at 80 m a.s.l. the permafrost temperature was -8.3 degrees C. The coastal stations of Molodeznaya at Enderby Land showed permafrost temperatures of -9.8 degrees C, Larsemann Hills Progress Station in the Vestfold Hills region-recorded -8.5 degrees C, and Russkaya in Marie Byrd Land, 10.4 degrees C.
