Ocean acoustic tomography (OAT) is a powerful approach for observation of deep and coastal water fluctuations. A precise estimation of travel time is essential for measuring ocean current using OAT. Generally, sound waveforms on reciprocal propagation that are transmitted at the same time are similar mutually, and it is considered that their correlation is high. However, we found that reciprocal sound waveforms sometimes become different in the continuous estimation of travel time difference. In this paper, we present the estimation results of the correlation between the reciprocal transmissions. We estimate the variation of the correlation of reciprocal propagated sound transmissions. A low correlation between the reciprocal propagated sound waveforms occurs at a certain rate on long range propagation in deep ocean. Acoustic measurement accuracy of current velocity in deep and coastal water is also estimated.
