Ocean bottom pressure measurements are important for the detection of long-term ocean bottom crustal deformations. However, the pressure values contain the drifts of the pressure gauges in addition to the pressure changes associated with crustal deformations on the seafloor. Therefore, it is necessary to calibrate the pressure gauges. We have been developing the in-situ calibration technology for ocean bottom pressure gauges. In this paper, we describe required specifications of mobile calibrator of ocean bottom pressure gauges. And, we report the level and attitude adjust system which is one of the components of the developed mobile calibrator of ocean bottom pressure gauges.
