AB: Two sections, 165$\deg$E and 180$\deg$, and along the equator in between, were sampled during WESPALIS 1 cruise in Oct./Nov. 1999. The high salinity tongue of the South Pacific subtropical overturning cell (STC) is described. In particular the pathways of the circulation are exhibited. Then a comparison with a 10-year climatology is performed and the deviations from the climatology are described in terms of heat content exchange between the upper ocean surface layers. It is shown that the heat exchange between the STC and the equatorial mixed layer is more intense during Warm events of ENSO.
