Glaciological Observations in the Vicinity of Mizuho Camp, Enderby Land, East Antarctica, 1970 (Reports of the Japanese Antarctic Research Expedition)
The Mizuho Camp, located at lat. 70°42.1'S and long. 44°17.5'E, about 300km southeast of Syowa Station, was established by JARE 11 (1970-71) wintering party in the winter of 1970 as an observatory of scientific researches on the inland area. During the 22 days trip the party made glaciolog...
