"We are pondering the possibility...of sending an expedition to the Russian Vostok station in East Antarctica," RIA Novosti quoted Mr. Chilingarov as sayin.
Chilingarove added that the Russian Geographic Society will continue its historic tradition of organizing expeditions to polar regions.
Lake Vostok is hidden some 4,000 meters beneath the ice sheet. In early 2011, the ice-drilling project to the sub-glacial lake yielded the deepest ice core ever recovered, reaching a depth of 3,720 meters. Ice-drilling works will resume in December.
