Two current meter moorings were deployed from the R/V Marion Dufresne in March 1992 between Roti Island and the Ashmore Reef and were recovered in April 1993 onboard the R/V Baruna Jaya 1. The mean transport was estimated between 3.4 and 5.3 Sv (1 Sv = 106 m3/s) for the Pacific water flowing toward the Indian Ocean through the Timor Passage. The upper part of the transport, from the surface to 500 m, shows a weak maximum during the southwest monsoon. An unexpected deep flow toward the Indian Ocean between 500 and 1550 m brings an important contribution to the total transport, which is minimum during August–September. As already noted in previous experiments, there is significant variability in the form of a succession of events within the 20- to 60-day range.
