Map of the Southern Ocean with ETOPO5 bathymetry indicated by coloured shading (green = 0-1000 m, pink = 1000-2000 m, purple = 2000-3000 m) plus a contour at 3000 m.
Map of the Australia-New Zealand region of the southern ocean with ETOPO5 bathymetry indicated by coloured shading and grey contours (every 1000 m). The white rectangles indicate candidate release sites.

The following figures show temperature-depth sections on the WOCE P28 (aka IX28) section between Tasmania and Antarctica. The profile name encodes the year and month (in a non-Y2K compliant way) eg. 9312 = December 1993. The shaded surface shows temperature, linearly interpolated between profiles. The yellow lines show temperature relative to surface temperature and the yellow shows mixed layer depth calculated from each profile, estimated as the depth at which the temperature drops 0.2°C below the surface value.
