Susan Wijffels and two anonymous reviewers made numerous helpful suggestions to improve the manuscript. The data from the TOGA buoys were made available to us by Nancy Soreide, Dai McClurg, and Linda Mangum from PMEL. Jim Mansbridge installed these data on our local computer network. The processed XBT data for the Indian Ocean and Indonesian Throughflow were provided by Lidia Pigot. Most of the figures were prepared with the public domain software package FERRET from PMEL. The project is largely supported by funding from the CSIRO Division of Marine Research and the Land & Water Resources Research and Development Corporation, Australia.
