昭和基地より南緯75度までの旅行およびクック岬への旅行における重力測定について
Along the inland traverse route from Syowa Station to location C21 (F451, 74°57'S, 38°27'E) and along the traverce routeon the sea ice in Lutzow-Holm Bay toward the Cook Point, the gravity was measured by Worden Gravimeter in 1961 On the inland traverse, the intervals of the observation st...
