By the way, the ARGOS system isn't showing any such warming.

Autonomous Lagrangian Circulation Explorer ßoats recorded temperatures in
depths between 700 and 1100 meters in the Southern Ocean throughout the
1990s. These temperature records are systematically warmer than earlier hydrographic
temperature measurements from the region, suggesting that middepth
Southern Ocean temperatures have risen 0.17¡C between the 1950s and
the 1980s. This warming is faster than that of the global ocean and is concentrated
within the Antarctic Circumpolar Current, where temperature rates
of change are comparable to Southern Ocean atmospheric temperature
increases.
