      <abstract xml:lang="ru">
        <p>В статье представлены результаты научно-исследовательских работ, проведенных в рамках 69-й Российской антарктической экспедиции на станции Восток. Основная цель исследований – комплексное изучение снежно-фирновой толщи с использованием прямых (бурение и анализ керна) и косвенных (георадиолокация и сейсморазведка) методов. В рамках исследований решались фундаментальные задачи, связанные с изучением структуры и динамики верхней части ледникового щита, а также прикладные, направленные на обоснование глубины размещения заряда взрывчатых веществ для проведения сейсмических работ с целью детального изучения подледникового озера Восток и выбора точки заложения скважины доступа к озеру. Получены данные о микроструктуре и физических свойствах снежно-фирновой толщи. Результаты позволят в будущем дополнить модель уплотнения фирна, необходимую для понимания эволюции ледяных зерен на ранних стадиях метаморфизма. Результаты работ внесли вклад в представление об особенностях строения приповерхностной части ледникового щита, позволили более точно определять структурные и физические характеристики снежно-фирновой толщи и льда, что может способствовать лучшему пониманию климатических и геологических процессов в Антарктиде.</p>

        <p>The article presents the findings from research conducted at Vostok Station during the 69th Russian Antarctic expedition. The primary goal of the research is to perform a thorough investigation of the snow-firn layer using both direct (drilling and core analysis) and indirect (georadiolocation and seismic exploration) methods. As part of the research, fundamental tasks related to the study of the structure and dynamics of the upper part of the ice sheet were addressed, as well as applied tasks aimed at justifying the depth of explosive charge placement for seismic work with the goal of conducting a detailed study of Lake Vostok and selecting the point for drilling access to the lake. Data on the microstructure and physical properties of the snow-firn layer were collected. The findings will allow for future improvements to the firn densification model, which is required to understand the evolution of ice grains during the early stages of metamorphism. The study's findings aided in the understanding of the structural features of the ice sheet's surface layer, allowing for more precise determination of the structural and physical characteristics of the snow-firn layer and ice, potentially leading to a better understanding of climatic and geological processes in Antarctica.</p>
