摘要：

[1] Using acoustic Doppler current profiler (ADCP) and conductivity-temperature-depth (CTD) data sets obtained from 1991 to 1993, volume, freshwater, and temperature transports through the Tsushima-Korea Straits are estimated. To remove tidal currents contained in raw ADCP data, tidal currents are calculated using harmonic constants obtained by ADCP surveys from 1998 to 1999. The annual mean and range of the volume transport through the straits are 2.4 Sv (1 Sv = 10(6) m(3)/s) and 0.8 Sv, respectively. These values are consistent with those of previous studies. The annually averaged freshwater transport is 33 x 10(6) kg/s, which is the same as the total river discharge around the Yellow and East China Seas. This suggests that the total river discharge and freshwater transport through the Tsushima-Korea Straits are the prominent two components in the freshwater budget, averaged annually in the Yellow and East China Seas. The annually averaged temperature transport through the Tsushima-Korea Straits is 0.17 PW.
