This paper describes the signal to noise ratio of the 200-Hz ocean acoustic tomography system as determined by the result of the performance test for tomographic monitoring conducted at the Kuroshio extension east of the Izu-Ogasawara Trench for a 3 month period between July and November 1997. After recovery of all the equipments, the retrieved data were read from the hard disk in the transceiver and analyzed. The average value of the signal to noise ratio in this experiment was approximately 20 dB which was an adequate value for the sound propagation up to 1000 km.
