AB: The complete set of the {\sc woce alace/palace} array in the Indian ocean and more than two years of data from the {\sc argo} experiment are examined to study the heat content variation in the Southeastern Indian Ocean. The circulation in this area is estimated via objective analysis. Various mixed layer depth definitions illustrate the importance of the seasonal cycle. Several methods to evaluate heat content calculations from the float profiles are employed, together with sensitivity tests, and compared with a newly developed satellite air-sea flux and {\sc ncep} climatological products. The question of a dominant balance in the oceanic budget between ocean heat storage and air-sea fluxes is studied with Ekman heat transport and advection estimates. The study also focusses on the formation and modification processes of Subantarctic Mode Water in this region of the Southern Ocean. The relation of the observed variability to the Antarctic Oscillation Index (AAO or SAM) is assessed.
