      <abstract xml:lang="ru">
        <p>Важнейшим и наиболее эффективным способом изучения ледников является: бурение скважин с полным отбором керна, однако процессы разрушения льда при вращательном бурении являются недостаточно изученными.</p>

        <p>The most important and the most effective way to study glaciers is: drilling of boreholes with complete coring, but the processes of ice destruction during rotary drilling are insufficiently studied.</p>
