Warming of the Southern Ocean Since the 1950s
Sarah T. Gille
Autonomous Lagrangian Circulation Explorer floats 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 mid-depth 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.
