Southern Ocean:
the major chokepoint is the Drake Passage between
South America and Antarctica; the Polar Front (Antarctic
Convergence) is the best natural definition of the northern extent
of the Southern Ocean; it is a distinct region at the middle of the
Antarctic Circumpolar Current that separates the very cold polar
surface waters to the south from the warmer waters to the north; the
Front and the Current extend entirely around Antarctica, reaching
south of 60 degrees south near New Zealand and near 48 degrees south
in the far South Atlantic coinciding with the path of the maximum
westerly winds
