In this observation, the authers set two observation lines in parallel to the latitude for investigating the structure and the characteristic of the tidal front formed in the Kurushima Channel, and carried out CTD observation of 12 times in total from April to October, 1999, and verified the reproducibility of the tidal front formation place. And we carried out ADCP observation of the shoal influence in the Higi Island northern part two times. The following results were obtained; As for CTD observation 1) The tidal front formation place on the both observation lines was almost corresponding to the numerical value shown by the expression, log_<10>(H/U^3)=2.5-3.0 and the reproducibility could be confirmed. 2) In the sea surface, the space distribution shape of tidal front was not so clear and the geographic characteristics of that were not observed enough in this observation. As for ADCP observation 1) The flow of the upper layer was greatly influenced by topographical features in the downstream part on the shoal and the neighbour. 2) The clear tidal eddy could not be confirmed around the shoal.
