This paper aims to design the system of ocean ambient noise measurement, the system is deployed with subsurface buoy, low frequency ambient noise of shallow water is measured by vector hydrophone. Vector hydrophone measures pressure and all three orthogonal components of particle velocity at a single point in space,the measured signal is preprocessed and sampled, the sampled data can be self-stored in subsurface buoy or transmitted to shore station by buoy. The method of noise measurement is discussed, the results of the sea trials show that the system is feasible and reliable.
