Seismological bulletin of syowa station, Aantarctica, 2003

Seismic observations at Syowa Station (69.0 degree S, 39.6 degree E), East Antarctica were started using a short-period seismometer with 1.0 s natural period in 1959. A long-period seismograph was installed and phase readings of the teleseismic events have been reported currently to the United States Geological Survey (USGS), and to the International Seismological Centre (ISC) since 1967. A three-component broadband seismometer (STS-1 was installed in 1989, for making a contribution to the Federation of Digital broadband Seismograph Networks (FDSN; http://www.fdsn.org/) as an important key station in the Japanese PACIFIC21 network (http://pacific21.eri.u-tokyo.ac.jp). A distribution of FDSN stations in Antarctic continent and the distribution of PACIFIC21 stations in 2003. All of the observation systems at Syowa Station were maintained in 2003 by one of the authors (J. Horiuchi) throughout the wintering season of the 44th Japanese Antarctic Research Expedition (JARE-44). He also scaled the arrival times for seismic events and reported to ISC and USGS through that wintering season. In this data report, we introduce the seismic observations at present in 2003, scaled read-out travel-time data and detected teleseismic earthquake list, in addition to the procedures for public use by Internet service.
