Starczynów „Desert” is located in the eastern part of the Silesian Upland (southern Poland) and makes a compact area with the occurrence of aeolian sands, which till the 1960s. were intensively blown. Its flat surface is diversified by many dunes of different shapes and sizes. Aeolian coversands are formed here as a cover of changing thickness. The „desert” is not a typical dry climatic area. The term Starczynów „Desert” refers to the area of occurrence of bare sands and aeolian processes and makes a geographical name that can be found on topographic maps. Its development was conditioned by human activity, where since the Middle Ages dense forest areas have been cut to obtain timber for the needs of contemporary mining and metallurgy of lead and silver ores causing the activation of aeolian processes at sandy substratum, built from the Vistulian proluvial-deluvial deposits. In the formation of the aeolian relief of Starczynów „Desert” it is possible to distinguish some stages of intensive wind activity: the 13th-15th centuries, the 16th-17th centuries, the turn of 18th and 19th centuries, the turn of 20th and 21st centuries. In present times human interference in the environment of Starczynów „Desert” consists of fixing sandy areas to protect them from deflation. Human damage exists here in the aeolian relief through terrain levelling and building fire escape roads. In the north-eastern part of the „desert” sand was exploited, therefore a sandpit appeared. This area was subject to the activity of mining for Zn-Pb ores, which caused numerous collapsed cones. In the last few years this part of the „desert” was properly reclaimed.

This paper presents the scope of geographical research conducted at Arctowski Station during the 30th Polish Antarctic Expedition. The research included meteorological, climatological, geomorphological and glaciological issues. During the expedition, research was conducted on sandur sediments on the outwash plain of Sphinx Glacier, the size of the aeolian transport, intensity of periglacial phenomena, and the way in which environmental conditions are recorded on quartz grains collected on the Admiralty Bay beaches. Detailed measurements of the basic meteorological components were made, geomorphological maps of the outwash plains of Sphinx, Baranowski, and Windy Glaciers were also completed.

W pracy zajęto się zagadnieniem zmian ukształtowania terenu województwa łódzkiego w okresie minionych 100 lat. Wobec szczupłości materiałów zaprezentowano jedynie szereg przykładów zmian eolicznych form rzeźby oraz wybranych form występujących na stokach – parowów i innych młodych rozcięć erozyjnych. Przekształcanie rzeźby eolicznej w ostatnim 100-leciu wiązało się zarówno z powstawaniem małych, inicjalnych pagórków eolicznych, jak i przeobrażaniem przez wiatr starszych wydm późnoglacjalnych. Zmiany parowów polegały na szybkiej transformacji kształtów ich zboczy pod wpływem uprawy ziemi i objęły od 2,18 do 51,4% stoków parowów. Podobnie jak w przypadku wydm następowała zarówno transformacja rzeźby wcześniej powstałych parowów neoholoceńskich, jak i tworzyły się na stokach młode i niewielkie, lecz już trwałe formy erozyjne. Analizę zmian rzeźby form eolicznych i form występujących na stokach poprzedzono rozpatrzeniem podatności obszaru województwa łódzkiego na działanie procesów eolicznych i stokowych.

The paper presents changes in the relief of the Łódź Voivodeship over the past 100 years. In view of a shortage of data, only a few cases of changes to aeolian landforms and to selected forms appearing on the slopes of gullies and other young erosional cuts were described. The transformation of aeolian relief in the last 100 years was associated with the formation of small, initial aeolian hillocks and with the transformation by wind of older late-glacial dunes. The changes to gullies involved rapid transformation of their slope profiles under the influence of soil cultivation and comprised from 2.18 to 51.4% of the gullies’ slopes. As in the case of the dunes, the transformation of the relief both of former Neoholocene gullies, and of young, small, but permanent erosional forms originated on the slopes took place. Relief analysis of aeolian landforms and features occurring on the slopes was preceded by consideration of the vulnerability of the Łódź Voivodeship area to aeolian activity and slope processes.
