Marine acoustic tomography subsurface is the main equipment to construct Marine acoustic tomography system.

Marine acoustic tomography is to take a "snapshot" of the ocean interior with the information carried by the ocean acoustic site. It can monitor the ocean in real-time, dynamic and on a large scale, and realize acoustic monitoring of the spatio-temporal changes of meso-scale processes.

Technical indicators:

Maximum working depth: 4000m;

Deep-sea low-frequency acoustic emission: frequency range (300Hz ~ 400Hz)

Deep sea acoustic reception: 16 yuan for hydrophone array, and the sensitivity of hydrophone is not less than -201db;
