Geophysical research from field observations by the Earth Science Division in the 38th Japanese Antarctic Research Expedition (1996-1998)
Several geophysical field research observations and geodesic surveys were conducted during the wintering season of the 38th Japanese Antarctic Research Expedition (JARE-38) in 1996-1998. Lithospheric structure and evolution of the Lutzow-Holm Bay region, East Antarctica were obtained from continuous...

Several geophysical field research observations and geodesic surveys were conducted during the wintering season of the 38th Japanese Antarctic Research Expedition (JARE-38) in 1996-1998. Lithospheric structure and evolution of the Lutzow-Holm Bay region, East Antarctica were obtained from continuous observations by portable broadband seismographs and from gravity surveys on outcrops around the Soya Coast region. Several GPS measurements both on the outcrops along the Soya Coast and on the ice sheet from the coastal area near Syowa Station to the inland of Dome Fuji Station area will give information on crustal uplift due to glacial rebound, on mass reduction and surface movement of the continental ice sheet, and on crustal thickness up to the Dome Fuji Station area.
