摘要：During the period of the second Japanese Antarctic Research Expedition, 1957-58, gravimeter observations were carried out on very closed pack-ice in Liitzow-Holm Bay and no pendulum observation was made in the Antarctic region. A Worden gravimeter used for this measurement had a stable and small drift, which was confirmed by continuous readings at Singapore and Cape Town, and also by examining the observed closure at Cape Town after the voyage in Antarctica. Based on this experience, it was expected that the gravity value at Syowa station would be determined by means of the gravimeter with the accuracy of few milligals. Thus, the gravimeter observation only was carried out in the third expedition and the pendulum apparatus was not employed.
