| Abstract |
The study of snow-firn sequences of glaciers by pit excavation takes a considerable amount of time. However, rapid penetration of snow-firn layers can be accomplished using large-diameter drills. A prototype of such a drill was designed and tested at Vostok Station in Antarctica by researchers V.V. Toskin, L.N. Manevsky and A.I. Tolstoy from the Ice Technics and Thermodrilling Laboratory of the Arctic Antarctic Institute. A 0.4-m diameter borehole, 6.5m deep was drilled with a vibratory drill. |
