The objective of this study is to model the mean and seasonal mass transport of the Pacific to Indian Ocean throughflow using variable-grid global Ocean General Circulation Model (OGCM) with fine grid (1°/6) covering the area from 20°S to 60°N and from 98°E to 156°E. The computations show that Indonesian Throughflow (ITF) mass transport, computed as a sum of through-strait transport, has maximum transport in Sept.(17.5Sv) and minimum transport in Jan.(9.5Sv). The annual mean ITF transport amounts to 14.5Sv. Twenty-two percent of this transport passes through Lombok Strait. Sixty-five percent of this transport passes through Timor Passage. Semi-annual variability is apparent in Lombok and Ombai Straits while annual variability is apparent in Timor Passage.
