Abstract
A Japanese Antarctic Station Syowa (69°S, 39°E) was established in East Ongul Island, Lützowholm Bay, East Antarctica for the International Geophysical Year (IGY) in 1957. Since that time, the following geodetical and geophysical observations have been carried out in the vicinity of Syowa Station: 1. Gravity: a) Continuous recording of gravity for detecting earth tides using LaCoste-Romberg gravity meter type D and G. b) Continuous observation by a superconducting gravimeter was started in March 1993; 2. Oceanic tide: Continuous recording since 1966; 3. Geomagnetism: a) Base line measurment. b) Continuous recording of long-period and short-period geomagnetic variations, and total intensity; 4. Seismology: Continuous recording by the three-component of long-period, short-period and broadband digital seismographs; 5. GPS/DORIS becon: Tracking continuously.
Syowa Station was selectied one of the 36 subset (A) stations of the International Absolute Gravity Basestation Network (IAGBN) by IAG. The measurments were made three times using four different absolute gravimeters in 1992, 1993 and 1995.
VLBI measurements were made among Syowa Station, Kashima (35.8°S, 140.7°E), Japan and Tidbinbilla (35.2°S, 149°E), Australia in 1990. Measurements will be done again in 1998. A route for repeat leveling survey was established in East Ongul Island in 1982. The leveling measurements were repeated in 1996 and 1997.
