CURRENTS

Results are shown from continuous current measurements across Korea-Tsushima Strait between May and October 1999.  The data are from eleven bottom-mounted Acoustic Doppler Current Profilers with pressure gauges.  These recorded full-depth profiles of currents along two lines, one at each end of the Strait.  The two sections show markedly different mean flow regimes. At the southern entrance, the cross-section flow varies smoothly across the channel, showing a broad maximum at mid-channel.  The northern section, is marked by strong spatial variability, but in the mean consists of two streams, one on each side of the strait.  Between the two is a regime of highly variable flow with a weak mean, presumably the wake from Tsushima Island. Flow variability in time is described by statistical measures and by snapshots of representative situations.
