Southern Ocean
the Southern Ocean is deep, 4,000 to 5,000 meters
over most of its extent with only limited areas of shallow water;
the Antarctic continental shelf is generally narrow and unusually
deep, its edge lying at depths of 400 to 800 meters (the global mean
is 133 meters); the Antarctic icepack grows from an average minimum
of 2.6 million square kilometers in March to about 18.8 million
square kilometers in September, better than a sixfold increase in
area; the Antarctic Circumpolar Current (21,000 km in length) moves
perpetually eastward; it is the world's largest ocean current,
transporting 130 million cubic meters of water per second - 100
times the flow of all the world's rivers
