Abstract
Surface meteorological data and upper ocean temperature profiles are obtain ed on-board ORV Sagar Kanya (cruise 120) during the second pre-INDOEX Campa ign (December 1996-January 1997) for evaluating the north-south variability of surface heat fluxes and upper oceanic heat content. Heat content in upp er 200 m decreased southward by 50 x 10(8) Jm(-2) along the ship's track. T here is a net heat loss on either side of the equator with a marginal gain at the equator. In the vicinity of the Inter-Tropical Convergence Zone arou nd 8 degrees S where sea surface temperature is maximum, the heat content i s conspicuously low, suggesting the divergence regime in the water column ( 0-200 m) due to a shear between southern equatorial and equatorial counter currents.
