The permanent research station in the High Arctic Zackenberg area in northeast Greenland was officially opened in August 1997. Temperature measurements, using TinyTalk miniature dataloggers, in a transect through a nivation hollow with a perennial snowpatch showed that during the 1995–96 season the BTS (bottom of the snow) temperature was about –10°C. The mean annual air temperature was –9.8°C. The BTS temperature was found to be less than 2– 3°C higher than the annual terrain surface temperature outside the snowpatch. As reported previously, two CALM grids were established at Zackenberg in summer 1996, with maximum average active layer thicknesses of 60 and 61 cm, and measurements continued in 1997. Studies of the soil water chemistry, physical and geochemical processes controlling pore water chemistry in the active layer and monitoring of the content of unfrozen water in the layer were started during the 1996 summer in Zackenberg. These studies are part of the long-term monitoring program of physical parameters under the GeoBasis program. Further information on the GeoBasis program and the research projects carried out at Zackenberg is given in Zackenberg Ecological Research Operations, 2nd Annual Report 1996, 80 p., Danish Polar Center, e-mail: email@example.com, or on the Web: http://www.dpc.dk/Sites/Zackenberg/FirstChoise.
A soil map of Greenland, scale 1:7,500,000, has been compiled by B. H. Jakobsen, Institute of Geography, University of Copenhagen. It was presented at the Cryopedology Conference in Russia in August 1997.
A project on water and chemical fluxes in frozen soil has been initiated by B. Elberling, Institute of Geography, University of Copenhagen. The project aims to provide a better understanding of the chemical processes and transport mechanisms within mining waste in arctic areas. This will provide guidelines for the management of mining waste to minimize the chemical fluxes of trace metals to the terrestrial and aquatic environment. A field study was initiated at the active sulfide mine in Nanisivik, Baffin Island, in northern Canada and will be followed up by detailed laboratory experiments with partly frozen waste material. This project is funded by the Ministry of Energy and the Environment (MIKA), Institute of Geography, University of Copenhagen and the National Environmental Research Institute, Denmark.
Rock glacier studies were carried out on Disko Island, West Greenland, by O. Humlum, Institute of Geography, University of Copenhagen during the summer of 1997. Flow rates and active layer temperatures were measured. Since 1983, Dr. Humlum has studied the characteristics of rock glaciers in different parts of the island, probably one of the areas of the world with the highest density of rock glaciers.
During the summer of 1997 another CALM grid was established close to Qeqertarsuaq (69°15′N, 53°30′W) on Disko Island by H. H. Christiansen, Institute of Geography, University of Copenhagen. The average active layer thickness was 57 cm. The mean annual air temperature is –4°C. Three TinyTalk miniature dataloggers have been installed in a profile from the terrain surface down to the top of the permafrost to log the active layer temperatures at 0.5, 30 and 74 cm.
