PLANNED EXPLOSION SEISMIC EXPERIMENTS IN EAST QUEEN MAUD LAND USING A PENETRATOR

In order to compare crustal velocity structures of East Queen Maud Land with those of Enderby Land, large explosion seismic experiments are planned along 24°E, for a 400km profile from Breid Bay through Asuka Station toward inland of the Nansen Ice Field. We are now developing an easily deployable (...

Description
Summary:In order to compare crustal velocity structures of East Queen Maud Land with those of Enderby Land, large explosion seismic experiments are planned along 24°E, for a 400km profile from Breid Bay through Asuka Station toward inland of the Nansen Ice Field. We are now developing an easily deployable (expendable) seismograph from the helicopter (Antarctic penetrator) to install 40-50 seismic stations along the profile with the elevation range from 0 to 3000m in a limited operational schedule. The penetrator must have memories to store the digital seismic records. The recorded data have to be transmitted by radio-telemetry to the central data acquisition system on the helicopter. This report briefly summarizes scientific objectives of the planned explosion experiments, and the status of the development of the Antarctic penetrator.
