In order to study geodynamics in relation to atmospheric, oceanographic and glaciological interactions on a global scale, adequate distribution of precise geodesy stations over the Earth is important. Syowa Station (69.0°S , 39.6°E ), Antarctica, serves as one of the observatories in the Southern Hemisphere. This report briefly summarizes the location coordinates of the geodetic sensors, and chronology of related activity as of 2005, based on standardized format sheets for each sensor monument. Exchange of these formatted sheets among Antarctic stations will give us a data base for reviewing and archiving geodetic activity in Antarctica. Local geodetic ties among their monument marks are updated from the results given by M. Kanao et al. (J. Geod. Soc. Jpn., 41, 357, 1995), including later surveying with improved accuracy.
