[STT50-P01] High quality 4-D active monitoring of an ocean bottom structure by using accurately-controlled sigal system and a mobile active seismic system
Keywords:active monitoring under sea floor, 4D active monitoring, seismic
We have been developing new method and technology to monitor the geophysical and/or geochemical changes in time and space of an ocean bottom structure such as resource reservoirs by accurately-controlled continuous signal system and using an autonomous underwater vehicle (AUV) (e.g., Tsuruga et al., 2010; Tachibana and Tsuruga, 2015; Mogi and Tsuruga, 2016). We have been developed portable seismic source system which consists of an active seismic source system and receiver array system with a small atomic clock IC tips in each system and they can synchronize / know the clock time by GPS system as an accurate clock in water.
In this meeting we show the result of sea trial using these active systems.
