The mean of six cruises from January 1984 throught June 1986, a relatively normal period, provides a reference with which the later sections are compared... Changes in the stratification along 165°E were corresponddingly large, reflecting both the geostrophic balance of the strong zonal currents and the changes in the volume of warm water in the Western Equatorial Pacific. The anomaly of warm water volume corresponded closely to the time integral of the warm water transport across 165°E. Local wind forcing and remotely forced waves were both important causes of the transport fluctuations. Winds, precipitation, and currents were all important factors determining the depth of the surface mixed layer and the thickness of the underlying barrier layer. The way in which these factors interact is a strong function of latitude.
