Morphological and physico-chemical properties of Cryosoils in the Bulgarian antarctic base on Livingston island, Antarctica

Under the global climatic changes and anthropogenic impacts on environment, information about characteristics specific features of soils in remote regions as Antarctica is valuable could be used references. This study focuses analyses original data physico-chemical composition micromorphological structure Cryosols, collected 2019 from sampling area Bulgarian Antarctic Base “St. Kl. Ohridski” located Livingston Island, Antarctica. The studied Cryosols are moderately acidic with slow incomplete transformation organic residues. carbon content low, except for formed under influence an ornithogenic factor. mezo- observations show a predominance mineral phase, weakly affected by weathering processes. Many soil pores voids observed, which facilitates water-air intra-soil exchange during short summer. showed evidence connection processes formation region pulsating degradation glaciers.
