11th Soviet Antarctic Expedition
One major task of the Expedition was to relay meteorological information to Soviet whaling ships in the southern latitudes.
This expedition was the first Soviet expedition to use aqua-lungs in biological exploration. Explorations using this technology were made from December to March in the Antarctic summer of 1966/7. The three months of work resulted in a large collection of animals which were presented to the Academy of Sciences of the USSR in Leningrad. During eleventh Antarctic Expedition in Nov. 1991/March 1992 SODAR (SOnic Detection And Ranging)was installed.
