Mechnikov National University popup.description2  Lithological, mineralogical and micropaleontological studies of the bottom sediments of the water areas adjacent to the Antarctic station "Akademik Vernadskyi" were carried out to reconstruct the paleoenvironment. In terms of lithology, bottom sediments in the area of the Penola Strait represented by silts with admixtures of sand and fragments of crystalline rocks. The presence of quartz, plagioclase, amphiboles, and siderite established in the mineral composition of bottom sediments. Among the authigenic minerals, there are bacteriomorphic framboid clusters of iron sulfide. As a result of micropaleontological studies of bottom sediments from the Penola Strait, 78 species of diatoms from 28 genera were identified. The distribution of diatoms has clear patterns that are related to the properties of surface waters and the duration of the sea ice cover. Schematic map of the underwater relief of the Argentine Islands area constructed based on the generated digital relief surface with a scale of 1:10000. Morphometric maps of such parameters as: spatial orientation of underwater slopes were constructed; angles of inclination of the underwater terrain; curvature of the profile of the underwater terrain; planned curvature of the underwater terrain; standard curvature of the underwater terrain. This made it possible to construct map of the most likely modern accumulation of bottom sediments in the area of the Argentine Islands. It has been established that the oldest sediments, the age of which is 10-12 thousand years old at the lower limit, will be found in the deep-water part of the French Channel and at its junction with the Penola Channel. Their expected capacity can be up to ten meters. Within the archipelago of the Argentine Islands, at depths of up to 100 meters, you can find younger bottom sediments with a time of formation from 5 thousand years ago to the present. Their expected capacity will range from 0.5 to 1 meter. Product Description popup.authors Kadurin Serhii V. Olshtynskaya Oleksandra P. Pedan Halyna S.
