Abstract
Hydrographic Department of Japan started sea level observation in 1960’s at Syowa Station as a part of Japan Antarctic Research Expedition, but its record was frequently broken. Through huge effort, we finally succeeded in taking the record continuously over years from 1981 using a pressure sensor of strain gauge. This continuous sea level record shows two remarkable phenomena. One is a long-term tendency of descending at the rate of about −0.45cm/year and another is a large seasonal change of sea level reaching about 26cm. Former is agreed with the geological fact of the ground rise assured by the geological remain of the elevated shore lines near the station. Latter is supposed as the seasonal change of coastal oceanographic condition, mainly caused by the coastal current circulation of the Weddel Gyre.
