概要 |
Characteristics of the current structure and seasonal variations of the Tsushima Warm Current through the Tsushima Straits are estimated using acoustic Doppler current profiler (ADCP) data from ferry ...based monitoring during about 10 years. In this paper, the features and mechanisms of current structures and volume transports are discussed, referring to recent and previous studies. The volume transport through the Tsushima Straits, averaged from February 1997 to February 2007, is 2.65 Sv (1 Sv = 10^6m^3s^<-1>) and those of the eastern and western channels are 1.20 and 1.45 Sv, respectively. The transport has strong seasonal variations with two maxima from spring to autumn (double peaks). Inflow transport through the Tsushima Straits into the Japan Sea is consistent with the outflow transport through the Tsugaru and Soya Straits of the results by other studies.続きを見る
