Gravity surveys are useful for profiling underground density structures. We propose a hybrid gravity survey method using gravimeters and gravity gradiometers to detect submarine ore deposits, such as massive sulfides buried below the seafloor. This paper describes a gravity gradiometer, which can be implemented in an AUV (Autonomous Underwater Vehicle) for this purpose. We developed a new gravity...
Gravity surveys are useful in profiling the underground density structure. We propose a hybrid gravity survey method using gravimeters and gravity gradiometers to detect submarine ore deposits. This paper describes the development of a gravity gradiometer for this purpose. The required resolution is estimated to be finer than approximately 10 E (= 1 × 10-8 /s2), considering typical dimensions of submarine...
High dense marine seismic observation is a key to understand earthquake system beneath oceans. We have been developing long-term ocean bottom seismometers (OBSs), which are able to store more than a year continuous seismic records on sea bottoms, since end of the 20th century, and they enable us to acquire many earthquake data when we have a high dense seismic network in marine region. In the last...
