50 Years of Antarctic Research Expeditions by the Geographical Survey Institute

Planning Department, Geodetic Department, and Topographic Department

Abstract

The Japanese Antarctic Research Expedition (JARE) started in conjunction with the International Geophysical Year (IGY) research program implemented from July 1957 to December 1958. From the first Japanese Antarctic Research Expedition (JARE-1) in 1956 to the latest one, JARE-48, the Geographical Survey Institute (GSI) has dispatched a total of 83 survey engineers to conduct geodetic surveys and take aerial photographs for preparing maps of Antarctica. This report summarizes the changes of surveying and mapping technology, and the achievements during the 50 years' history.
