Аннотация

Сделан обзор результатов дистанционных исследований подледникового оз. Восток. Установлено, что толщина ледника непосредственно в пункте бурения по сейсмическим данным составляет 3760±30 м, а по радиолокационным – 3775±15 м. Таким образом, погрешность измерений толщины ледника дистанционными методами составляет менее 0,3%. Толщина ледника в районе оз. Восток изменяется от 1950 до 4350 м. Средняя глубина озера – около 400 м, а объём воды в нём – 6100 км3. В пределах акватории озера обнаружено 11 островов, а вокруг озера выявлено 56 подледниковых водоёмов. Само оз. Восток представляет собой изолированную систему.
