Abstract

Results of geological interpretation of air photos from selected parts of southern Spitsbergen are presented. Quaternary and some older landforms and deposits distinguished during the photointerpretation are described on the basis of their discrimination features, as well as origin and spatial realtions. On this ground a code for interpretation of relief elements in polar areas was prepared. A geological interpretation of air photos completed by absolute datings of different deposits enabled to connect studied landforms with the Late Quaternary main glacial episodes. Sea and glacier extents in the northwestern Sörkapp Land, from the Wedel Jarlsberg Land Glaciation (Saale) to the Little Ice Age (Holocene) are presented.

Abstract

Paper presents the description and floristic and ecologica characteristics of three plant communities on the area of Jasnorzewski Gardens in the region of Arctowski Station (Polish Academy of Sciences) on King George Island. They are: 1) Deschampsio antarctici-Colobanthetum quitensis, 2) Polytrichetum alpini, 3) Calliergidio austro-straminei-Calliergonetum sarmentosi. All communities show a considerable differentiation to several variants. Distribution of plant communities on the studied area is presented on a map based on computer analysis of multispectral air photographs.

Abstract

A map was made of the distribution of macroalgae groupings in shallow waters of Admiralty Bay. The map was plotted on the basis of analysis of color reversal air photograph taken from a helicopter. A significant agreement of the results of the pictures analysis with the field studies was found. Also a number of areas not covered by field studies was determined as the ones of probable occurrence of macroalgae. A detailed map of distribution of four distinguished forms of macroalgae groupings was plotted for a small area in the region of Shag Point. Each of these forms is characterised by different association of algal species.
