A workshop on "Public Use and Scientific Study of Broadband Seismic Data at Syowa Station, Antarctica" was held on January 25,1996 at the National Institute of Polar Research, with 12 participants. The history and present status of seismic observations were reported, followed by presentations concerning scientific studies using broadband data in Antarctica. The main contributions are (1) studies of the velocity structure and anisotropy in the crust and upper mantle using short-period body waveforms and travel time data and (2) analyses of the heterogeneity and anisotropy of seismic wave velocity in the core and the lowermost mantle by using short period core phases and free oscillations of the Earth. Finally, discussions concerning data archiving, public use and future plans of the Japanese Antarctic Research Expedition (JARE) were conducted in regarding to the above scientific results.
