Abstract
Summary. The effects of ocean tides on the M2 tidal changes of gravity observed at several stations in Japan have been estimated by applying the Green's function given by Farrell in 1972. Gravity tides observed by using an Askania Gs-11 gravimeter (No. 11 1) from 1957 to 1959 (ICY) are generally small compared with theoretical values expected from the Gutenberg-Bullen A Earth model. Though results from recent observations by new Askania gravimeters and a LaCoste & Romberg gravimeter show better agreement with the theoretical values, the differences remaining are not negligible. A signifi- cant alteration of the ocean tidal model near Japan is required in order to explain such differences.
