“…The soils of the Gröndalen catena differ in their textural characteristics from the soils of the other cat enas described in the previous paper [13]. The content of fine particles and, particularly, clay particles in the soils of the Gröndalen catena is significantly higher (Fig.…”

“…There are also flat and slightly convex interfluves with a layer of bedrock residuum (eluvium) on the surface [8,14,16]. The genetic characterization of the soils developed on marine and structural terraces in the areas of the Isf jord and Grönfjord catenas was given earlier [13]. It was shown that the soils belonging to the type of gray humus (soddy) soils with the O-AY-C profile are developed in these areas from the parent materials of different origins and textures.…”

The genetic characterization of soils developed from alluvial and proluvial deposits in the Grön dalselva River valley (West Spitsbergen) is presented. These soils are compared with analogous soils formed on marine terraces along the coasts of Isfjord and Grönfjord. Gray humus (soddy) soils with an O-AY-C profile have been described on parent materials of different origins, including alluvial and proluvial sedi ments. The texture of the soils in the Gröndalselva River valley varies from medium to heavy loam and differs from the texture of the soils on other geomorphic positions in the higher content of fine particles. The soils developed from the alluvial deposits are characterized by their richer mineralogical and chemical composi tion in comparison with the soils developed from proluvial deposits, marine deposits, and bedrocks. All the deposits are impoverished in CaO. No differentiation of the chemical composition of the soils along the soil profiles has been found in the soils of the coastal areas and the river valley. Some accumulation of oxalate soluble Al and Fe compounds takes place in the uppermost mineral horizon. The soils of all the geomorphic positions have a high humus content and a high exchange capacity.

“…It should be also noticed that for some soil types significant differences in interpretation in sense of classification state compared to the previous works conducted in the area of study (Pereverzev et Litvinova 2010) were determined. This confirms the thesis about the non-stable state of polar soils classification and taxonomy.…”

Vertical electrical resistivity sounding (VERS) of soil-permafrost strata has been performed during the field work within the sea terraces of Gronfjord (Svalbard archipelago, West Spitsbergen island). Vertical electrical resistivity sounding of soilpermafrost strata was performed by portable device LandMapper. Then these data have been analyzed via ZondIP software (1d model). Apparent electrical resistivity values on the soil-permafrost strata usually change rapidly. It was established that studied soils with different origin and morphological properties are referred to 2 trunks, 2 orders, 4 types and 7 subtypes. Histic Gleysols, Cryosols, Gleysols and their subtypes have been investigated within the key plots (Grendasselva, Aldegonda rivers and catena on the sea terrace in surroundings of Barentsburg aerodrome). Several trends in profile distribution of electrical resistivity values have been distinguished. The main is connected with monotonous increasing of electrical resistivity values with a depth. Values of apparent electrical resistivity increase rapidly on the border of active layer-permafrost layer. The contrasts in profile distribution of electrical resistivity values are caused mainly by differences in water content, texture class and degree of strata heterogeneity (due to cryogenic processes). The depths of active layer-permafrost boundary have been distinguished using ZondIP software. Regional differences in this indicator may be explained not only by local differences in thermal regime of soil and permafrost layers, but also by different character of anthropogenic influence on key plots. Vertical electrical resistivity sounding method provides significant information for understanding soil electrical properties without any mechanical disturbances of soil cover. The data obtained is clearly coincided with field work data on soil morphology.

“…First, a typical terrace consists of slightly elevated ridge positions and lower trough positions (Pereverzev and Litvinova, 2010) and thus contains altitude differences resulting in different hydrological conditions that affect soil formation (Makaske and Augustinus, 1998;Scheffers et al, 2012). Second, geomorphic processes may have a different effect on not only ridges and troughs but also terraces at different positions in the landscape (Pereverzev and Litvinova, 2010) -particularly where a marine terrace complex is part of otherwise mountainous topography. Erosion and deposition can occur with different rates on different terrace levels (Strzelecki, 2012).…”

Abstract. Soils in Arctic regions currently enjoy attention because of their sensitivity to climate change. It is therefore important to understand the natural processes and rates of development of these soils. Specifically, there is a need to quantify the rates and interactions between various landscape-and soil-forming processes. Soil chronosequences are ideal natural experiments for this purpose. In this contribution, we combine field observations, luminescence dating and soil-landscape modelling to improve and test our understanding of Arctic soil formation. The field site is a Holocene chronosequence of gravelly raised marine terraces in central Spitsbergen.Field observations show that soil-landscape development is mainly driven by weathering, silt translocation, aeolian deposition and rill erosion. Spatial soil variation is mainly caused by soil age, morphological position within a terrace and depth under the surface. Luminescence dating confirmed existing radiocarbon dating of the terraces, which are between ∼ 1.5 and ∼ 13.3 ka old. The soil-landscape evolution model LORICA was used to test our hypothesis that the field-observed processes indeed dominate soil-landscape development. Model results additionally indicated the importance of aeolian deposition as a source of fine material in the subsoil for both sheltered and vegetated trough positions and barren ridge positions. Simulated overland erosion was negligible. Consequently, an un-simulated process must be responsible for creating the observed erosion rills. Dissolution and physical weathering both play a major role. However, using present-day soil observations, the relative contribution of physical and chemical weathering could not be disentangled. Discrepancies between field and model results indicate that soil formation is non-linear and driven by spatially and temporally varying boundary conditions which were not included in the model. To conclude, Arctic soil and landscape development appears to be more complex and less straightforward than could be reasoned from field observations.
