There are also significant salinity anomalies in the
deep Indian Ocean that are coherent with those at the
surface. For example, in phase 8 positive salinity anomalies
extend from the deepest level at 1400 dbar up to the
surface in the central Indian Ocean (Fig. 16h). These
are dynamically consistent with the temperature anomalies
in the deep ocean, as both variables imply downward
displacement there (Fig. 17).
