摘要：

Time series of Kuroshio transport across a section off Shikoku, Japan are derived. Fluctuations of the whole eastward transport are primarily caused by an offshore local stationary anticyclonic eddy. In contrast, throughflow transport, excluding the eddy's contribution, reflects variations of western-boundary transport expected to compensate for interior Sverdrup transport (WBST). The mean throughflow transport is considerably smaller than the mean WBST. Throughflow transport exhibits a long-term decreasing trend, consistent with WBST. On an interannual scale, throughflow transport lags behind WBST by approximately 5 years. Mean throughflow transports during large meander periods and non-largemeander periods are almost the same.
