International Permafrost Association Country Reports
In the Austrian Alps permafrost research takes place at selected sites of the Hohe Tauern Range and the Tyrolean Alps. Special emphasis is placed on annual measurements of the following parameters on active rock glaciers: temperature measurements on the surface and within the active layer of permafrost areas, hydrological investigations (temperature, water storage and discharge, hydrochemical characteristics), and geodetic and photogrammetric monitoring of surface velocity and vertical changes of active rock glaciers.
Research in Disko Island (70°N) relating to rock glacier dynamics and surface climate has been continued by Ole Humlum, University of Copenhagen. Both air temperatures, ground surface temperatures, as well as active layer temperatures, are being measured. The snow cover duration has been studied at two rock glaciers by use of automatic digital cameras.
The Bundesanstalt für Geowissenschaften und Rohstoffe, Hannover, and the Centre d’Ètudes Nordiques, Université Laval, Québec (Georg Delisle), joint-project on investigation of the permafrost development in emerged marine sediments near the eastern shore of the Hudson Bay continues into its second year.
The Kazakhstan Alpine Permafrost Laboratory of the Permafrost Institute SD, RAS continued monitoring of the thermal regime of the permafrost and the depth of seasonal freezing ground in the northern Tien Shan (basin of river Bolshaya Almatinka, Transili Alatau Ridge).
Several New Zealand programmes were commenced or continued during the past year in the area of permafrost and periglacial processes in both New Zealand and Antarctica. M. B. Scott, K. J. M. Dickinson, A. F. Mark, B. I. P. Barratt, B. J. Sinclair (University of Otago) initiated a study of the invertebrate diversity of threetypes of alpine patterned ground on the Old Man Range of Central Otago.
