In this paper, based on the field observation, the characteristics of stratified flow and that of intemal tide
in Gokasho Bay were investigated. Observation period was from 16 June to 1 July '93. Current meters with
temperature sensor were moored at three or two layers at fourteen points, three of those were out of the bay,
two were near the mouth and nine were in the bay. Sampling interval was ten minutes.
Intemal tides were apparently observed around the bay. The amplitude of the intemal tide was decreased
toward the inner part of the bay, that is ten and some meters near the mouth of the bay, some meters near the
central part and very small at the innermost part. It is concluded that the intemal tide has an important effect
on the environment of the bay except the innermost part of it.
