| Title | Acitve source digital seismic waveforms by SEAL exprolation |
| Sub-Title | Acitve source seismic records on the Mizuho Plateau |
| Data Summary | Deep Seismic Surveys (DSS) were carried out in 2000 and 2002 austral summers on the continental ice-sheet of the Lutzow-Holm Complex (LHC), Eastern Dronning Maud Land, East Antarctica . The surveys were carried out as a program of the "Structure and Evolution of the East Antarctic Lithosphere (SEAL)" by JARE.. Detailed crustal velocity models and reflection sections were obtained in the LHC. In both surveys, more than 170 plant-type 2 Hz geophones were installed on the continental ice-sheet totally 190 km in length. A total of 8,300kg dynamite charge at the fourteen sites on the Mizuho Plateau gave information concerning the deep structure of a continental margin of the LHC. Archived digital wavoforms are availrable from Library Server of Polar Data Center of NIPR. |
