Paper described geomorphological characteristics of landform sets which occur on research areas investigated by Polish geomorphologists on Spitsbergen. These area involve four areas along the western coast of Spitsbergen, i.e. vicinities of the Kaffiøyra, the Werenskioldbreen, the Calypsostranda, and the Hornsund, as wel as one area located in the central part of Spitsbergen, i.e. vicinity of Billefjord with special emphasis on surroundings of the Petuniabkukta. Landforms are characterized in different morphogenetic terms, mainly glacial, peryglacial, deundational, slope, fluvial, even eolian factors and processes.

Powstałe z inicjatywy A.B.Dobrowolskiego Towarzystwo Geofizyków w Warszawie (1930) oraz Polskie Koło Polarne (1936?, 1938) odegrały istotną rolę w organizacji polskich badań polarnych w okresie międzywojennym. Członkami TGW byli - C. Centkiewicz, kierownik polskiej wyprawy II Międzynarodowego Roku Polarnego na Wyspę Niedźwiedzią (1932/1933), K. Jodko-Narkiewicz - uczestnik trawersowania Spitsbergenu (1936). A.B.Dobrowolski z TGW patronował polskiej wyprawie na Spitsbergen w 1934 r., a z Polskim Kołem Polarnym - w 1938 r. Z TGW związany był równieS najbardziej aktywny badacz polarny okresu międzywojennego (jak również powojennego) - S. Siedlecki. Dzięki działalności tych osób Polska znalazła się w czołówce państw prowadzących badania polarne, a niebędących państwami polarnymi.

Founded at the initiative of A. B. Dobrowolski, the Society of Geophysicists in Warsaw (Biuletyn 1930) and the Polish Polar Club (1936?, 1938) played a major role in organizing Polish polar research in the inter-war period. The TGW's members included C. Centkiewicz - leader of the Polish expedition to Bear Island in the 2nd International Polar Year (1932/1933), and K. Jodko- Narkiewicz - a participant in the traverse of Spitsbergen (1936). A. B. Dobrowolski with the TGW was the patron of the Polish expedition to Spitsbergen in 1934, and with the Polish Polar Club - In 1938. The most active inter-war (and post-war) polar researcher, S. Siedlecki, was also involved in the TGW. Thanks to the activity of these people, Poland became a leader in polar research among non-polar countries.
This paper presents results of a study on the relationship between features of side scan sonar acoustic imagery of zones with active bedforms and geomorphologic seafloor characteristics. Acoustic measurements were conducted in Hornsund, a Svalbard fjord representing a periglacial environment with great intensity of morphodynamic processes and rapidly progressing changes of tidewater glaciers. Due to the intensity of these processes, Arctic fjords are the most promising areas to study the effects of climate change on the ecosystem. Acoustic identification of sedimentary structures and morphological forms created by currents and iceberg transport of glacier sediment away from the ice margin was performed. The spectral and fractal features of the recorded signals were analysed. The proposed analysis scheme allows identification of the morphodynamic active zones in the changing Arctic fjord environments. Measurements of acoustical features of seafloor surface were made during the 2006 Arctic cruise of r/v Oceania.
