Abstract

Metal contents in the tundra soils (Gelic Regosols, Gelic Gleysols, Gelic Cambisols) of the maritime lowland of Kaffiöyra, in the western Spitsbergen seashore are presented in this publication. The average heave metal contents in samples collected from the depth layer 0—130 cm are follows: Fe 2.9%, Mn 392 ppm, Zn 75 ppm, Cu 23.4 ppm, Ni 24.1 ppm, Co 7.4 ppm, Pb 12.5 ppm, Cd 0.24 ppm. The surface soil layer 0 to 25 cm is poorer in Ca and Mg than the underlying layer 25 to 130 cm. The heave metal contents like Fe, Mn, Ni and Co, are also somewhat lower in the upper layer. The enrichment indices of Pb and Cd are equal in the surface soil layer 1.16 and 1.23 respectively. Correlation coefficients between each studied element and organic carbon, and, on the other hand, soil separates < 20 μm and < 2 μm are very low.

Abstract

In surface horizons of Gelic Regosols. Gelic Gleysols and Gelic Cambisols from 5 sites in Kaffiöyra. 26 taxa of blue-green algae have been determined. Species of the genera Gleocapsa, Schizothrix, Tolypothrix and Calothix were the most common. In Gelic Regosols blue-green algae formed during the last 100 years the 0.5 cm thick horizon A, containing 8.6% of humus.

Abstract

Distribution of the following elements: Na, K, Ca and Mg, and heavy metals: Fe, Mn, Zn, Cu, Ni, Co, Pb and Cd was analysed in the Gelic Cambisols profile from Kaffiöyra, Spitsbergen. The leaching of Ca, Fe, Mn, Co and Cu, and in a less degree Mg and Ni downward the profiles occurs in the studied soil due to pedogenic processes. The surface soil horizon is strongly enriched in Na and K of marine origin and Pb and Cd from anthropogenic pollution of the distant atmospheric transports.

Abstract

On the basis of elemental composition, optical properties in the visible region, infrared spectra and thermal analysis (TG, DTG, DTA), humic acids of tundra soils in Spitsbergen are found to be more similar to fulvic acids than to humic acids of soils from other soil-climatic zones. The authors claim that it results from climatic conditions (low temperature, considerable humidity, alternation of freezing and thawing) and specific biochemical composition of tundra plants (predominance of plants devoid of lignin) which constitute substratum of the studied humic acids.
