2006

In February 2006 the working group directed by Ana L. Ahumada (Inst. of Quaternary Geology and Palaeoclimates, Miguel Lillo Foundation) installed data loggers on the cryoplanation surface (27º7’ S, 66º2’ W) at Abra de la Apacheta, Sierra de Aconquija, Tucumán, at 4825 m asl, to monitor temperatures, as air temperatures above 2000 m asl were not available in that region.

Most permafrost related research in Austria is carried out by the University of Innsbruck, the two Universities in Graz, Joanneum Research (Graz), the Geological Survey of Austria (Vienna), and the Central Institute for Meteorology and Geodynamics (Vienna & Salzburg).

A team from Ghent University (Jean Bourgeois and Wouter Gheyle, Dep. of Archaeology; Rudi Goossens and Alain D. Wulf, Dep. of Geography) investigated frozen tombs (kurgans) in the Altai Mountains, in collaboration with Sergei Marchenko (University of Alaska, Fairbanks).

At the University of Ottawa, Antoni Lewkowicz and students carried out several permafrost-related projects in the Yukon.

The following is a summary of an extensive report by China. The complete report is posted on the IPA web site.

As part of the Zackenberg Basic monitoring programme in Zackenberg, Northeast Greenland, the geographical and the climatic programmes, GeoBasis and ClimateBasis collect data of climatic, hydrological and terrestrial variables describing the dynamics of the physical and geomorphological environment in this high Arctic location.

Some periglacial geomorphology projects were recently completed.

The polar research group of the Laboratory of Physical and Environmental Geography of Clermont-Ferrand (GEOLAB – UMR 6042-CNRS) carried out several activities of interest to the periglacial community. Following the SEDIFLUX International Meeting Shifting Lands held in Clermont-Ferrand in 2005 (see Frozen Ground 29), two special issues of Geomorphology and Géomorphologie were coordinated by Samuel Etienne and Denis Mercier.

The ninth expedition to the Lena River Delta was carried out from May to September by the Alfred Wegener Institute for Polar and Marine Research (AWI) under the aegis of its Department of Periglacial Research (H.-W. Hubberten and colleagues).

Cryoturbation is very active in Iceland due to frequent freeze-thaw cycles in the oceanic sub-arctic climate, and most soils and land surfaces show some geomorphic surface features that result from frost activity.
