Abstract

Measurements of CO2 concentrations in soil air were taken in the summer seasons of 1998 and 2001 in SW Spitsbergen. The measurements were carried out in three small non-glaciated catchments in the Hornsund region close to the Polish Polar Station. The preliminary measurements were made using a Dräger's pump and ampules which contained an alkaline absorbent (1998). Later (2001), a new more accurate apparatus which uses a gravimetric method was tested. A variety of different geographical situations was chosen for the CO2 measurements. These included areas which differed in respect of the local hydrology, terrain relief, exposure to solar radiation, distance from the sea and quantity of seabird excrements in the soil. The measured concentrations of soil CO2 varied between 0.05 and 0.3% (with one exceptionally high value close to 0.5%). Owing to the local conditions, the differences between CO2 concentrations seem closely to relate to the specific properties of each catchment. Much of the biogenic CO2 present in water that circulates in tundra catchments which have a limestone foundation becomes involved in the dissolution of that limestone. In July 2001, about 40% of the CO2 was used in the dissolution of the carbonate rocks (30.3 kg/km2 month), the “free” CO2 being transported to the sea at Isbjřrnhamna Bay (40.4 kg/km2 month). In contrast, the water flowing through acidic rocks are rich in “free” CO2. The concentrations of dissolved and transported HCO3– ions from the polar catchments are closely correlated with variations in the daily production of biogenic CO2.

Abstract

This paper gives the results of investigations carried out in the Fugleberget basin which lies on the northern shore of the Hornsund Fiord, in the unglaciated region of raised sea terraces and on the slopes of the Fugleberget (569 m a.s.l.) and the Ariekammen (511 m a.s.l.). The investigations were carried out between 23 July, 1979 and 4 September, 1980, including the polar night. The Fugleberget basin represents well the area of sea terraces and coastal mountains uncovered with glacier and occupying large areas in West Spitsbergen. These areas are characterized by the presence of permafrost. The aim of investigations was to determine such fluvial processes as the duration of the hydrological period, the manner of water supply to the basin and an attempt to define the elements of the water balance. In addition studies were made on hydrological processes, particulary changes in the chemical composition of water, and the magnitude of denudation determined.

Abstract

This paper contains thsults of hydrological and hydrochemical investigations carried out in the basin of Werenskiöld Glacier against the background of determining climate elements. It also gives chosen elements of the water balance and mass balance determined from year-long investigations of the polar hydrological year 1979-1980.
