| 内容記述 | Free-fall pop-up ocean-bottom seismograph systems were developed and tested. The free-fall pop-up ocean-bottom seismograph has many merits compared with the anchored-bouy ocean-bottom seismograph commonly used in Japan. Two of its merits are that the size of this system is small and the weight is light. Ontheotherhand, one of its demerits relates to the difficulty involved in recovering OBS. The free-fall pop-up ocean-bottom seismograph is composed of a sensor and recording system, pressure case, release-mechanism, ballast, buoyant body, and a finding system. For our system, we developed a low-power recording device. Both syntactic foam and glass sphere were adapted in order to obtain a buoyant force. To increase the safety of the system, a double release-mechanism was adopted. A 27 MHZ radio beacon, and a flash beacon and flag were used as the finding system. A detailed description of the system is provided in this paper. | |||||
