Characteristic Seismic Waves Associated with Cryosphere Dynamics in Eastern Dronning Maud Land, East Antarctica

Figure 1

Location map of the seismic profile for SEAL-2002 exploration (solid line; between A and B), together with SEAL-2000 profile (broken line) on the Mizuho Plateau, Eastern Dronning Maud Land, East Antarctica. The data retrieved by SEAL-2002 exploration were used in this study. Names of nearby Japanese stations are as follows: Syowa St. (SYO) at the coast of Lützow-Holm Bay and Mizuho St. (MZH) on ice-sheet plateau. The intersection station of the two seismic profiles (C) is indicated by a solid triangle (H176 and HM067 are station codes for SEAL-2000 and SEAL-2002, resp.). The distance measured from the southwestern terminal (A) along the SEAL-2002 profile is utilized as the abscissa in several record sections in this paper (Figures 3, 4, 6, 7, 9, 10, 11, 12, 13, 14, and 15). The extended area in Antarctic continent is indicated by solid rectangle as shown at the lower left.
