Investigation of deep ocean bottom by penetrator probe

Abstract

Penetrator probe of JAXA for planetary exploration was developed sucessfully in 2010, and was confirmed by twice QT tests. Apply to the terrestrial use is easy, and various instruments can be installed in a penetrator probe, because of the more mild environmental conditions. The onboard instruments of penetrator are protected by surface-body and potting fabrics, and water proof character of the penetrator can be realized by these. The penetrator probe possesses own electric power of super lithium battery, and acts as an independent passive observation station. The porbe can be operated as a active device, such as seismic source. The probes would obtain several new information when they are operated as network stations. If penetrator probes can be deployed in a bore hole, several active and/or passive information along the depth will be obtained.
