%{\color{blue}Fig. \ref{fig:mxldcyle} shows seasonal cycles of mixed layer depth at three selected latitudes, which intersect areas of year-round deepest mixing in the Inidan and Pacific sectors of the midlatitude Southern Ocean. In general, model mixed layer depth undergoes a strongly seasonal cycle, with deepest mixing (mixed layer depth $>300m$, gray-shaded in Fig. \ref{fig:mxldcyle}) in the sprint (August-December) and shallower mixing ($<100m$) in alte summer-autumn (January-June). At $55^{\circ}\mathrm{S}$, $160^{\circ}\mathrm{E}-180^{\circ}\mathrm{E}$, south of New Zealand, deep mixed layers persist almost all year (with the exception of brief restratification in the February-March).}
