During the expedition "Spitsbergen 1979/80" the authors prepared a geomorphologic map of the area to the north of Hornsund, between the Torell Glacier and the Treskelen Peninsula. Fifteen raised marine terraces were distinguished. Basing on field morphometric sections, quite a detailed distribution of the terraces at a seaside plain and in side valleys was noted. Also, the previous Polish studies over this part of the Svalbard Archipelago were taken into account. The terraces occur at the following altitudes: 220—230 m, 200—205 m, 180—190 m, 100—115 m, 80—95 m, 70—75 m, 60—65 m. 45—46 m, 40 - 46 m, 32—35 m, 22—25 m, 16—18 m, 8—12 m, 4.5—6 m and 2 m a.s.l. (Figs. 2—5). The terraces are not evenly distributed and they possess a varying structure. The authors, due to absence of other chronologic evidence but on the ground of a morphologic analysis and radiocarbon data (presented by Birkenmajer and Olsson 1970) suppose that only the lowest terraces have been formed in a postglacial period.

Marine rock-accumulative terraces at 2-230 m a.s.l. in the southern Sörkapp Land are typical for glacioisostaticly uplifted areas. The Holocene terraces reach up to 19 m a.s.l. An outstanding coastal ridge at 9-10 m a.s.l. was radiocarbon-dated at 6580±160 years B.P. No marine transgression during the Holocene on higher and older terraces was noted, what is also confirmed by well preserved raised storm ridges. Any of glacial advances during the Holocene were more extensive than the one of the Little Ice Age. However the Pleistocene glaciations were more extensive. Among glacial landforms in the area there are: ice-cored frontal and lateral moraines up to 70 m high, plains of ground, ablation and fluted moraines, complexes of glaciofluvial fans. The glaciers retreated 0.3-2 km since 1936 i.e. ca 10 m a year on the average. There are large consequent structural landslides on eastern slopes of Keilhaufjellet.

Soils, having a well-developed sequence of A and Bw horizons, are widespread on the uplifted marine terrace 8- 12 m a.s.l. in the proximity of Nottinghambukta Bay . The present-day origin of these soils is however questionable, while similarly developed soils, but buried under the cover of the youngest till were found on a forefield of the Werenskiold Glacier. To quantify an intensity of the soil-forming process under present climate conditions of SW Spitsbergen , the chronosequence of soils developed from the Recent, up to 70 year-old moraines, was studied on the forefield of Werenskiold Glacier. Significant dissolution of CaCO3, decrease of pH, leaching of calcium and magnesium, increase of amorphous iron content, as well as an accumulation of organic matter and initial formation of aggregate soil structure were observed within the surface layer of recent till. The 70 year-long period of pedogenesis was, however, too short for a distinct morphological differentiation of the subsurface B horizon. It is concluded, that deep and structural Bw horizons of some surface and buried soils are relicts of a much longer period of relatively warm climate before the last transgression of glaciers.
