11th Soviet Antarctic Expedition
Encyclopedia
The Eleventh Soviet Antarctic Expedition was an expedition by the Soviet Union
to Antarctica based at Mirny Station
.
The Expedition did research
into; the climate
, the state of the ionosphere
, the northern lights
, cosmic rays, the geomagnetic field, and the source of radio waves
.
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-lung
s 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
