Abstract
We have been developing Ocean Acoustic Tomography System at Japan Marine Science and Technology Center. Our objective is to measure real time 3-dimensional temperature and current velocity in an area of 106 km2(103 km × 103 km) using low frequency sound techniques. We developed 200 Hz low frequency sound source for this system in 1992. Due to the mechanical limitation of pressure compensator of the source, falling speed should not exceed 2.0 m/s. Completion of the mooring techniques is essential for the ocean acoustic tomography system. For this purpose, using acoustic navigation system, we measured transponder's position on the mooring system when we deploy the mooring system.
In this paper, we present 200 Hz sound source mooring system and measurement method, and using measurement and numerical simulation, we analyzed falling motion for ocean acoustic tomography mooring system.
