Resources (regulates fishing)
note: many nations (including the US) prohibit mineral resource
exploration and exploitation south of the fluctuating Polar Front
(Antarctic Convergence) which is in the middle of the Antarctic
Circumpolar Current and serves as the dividing line between the very
cold polar surface waters to the south and the warmer waters to the
north

Geography - note:
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

Economy Southern Ocean

Economy - overview:
Fisheries in 2000-01 (1 July to 30 June) landed 112,934 metric
tons, of which 87% was krill and 11% Patagonian toothfish.
International agreements were adopted in late 1999 to reduce
illegal, unreported, and unregulated fishing, which in the 2000-01
season landed, by one estimate, 8,376 metric tons of Patagonian and
antarctic toothfish. In the 2000-01 antarctic summer 12,248
tourists, most of them seaborne, visited the Southern Ocean and
Antarctica, compared to 14,762 the previous year.

Transportation Southern Ocean

Ports and harbors:
McMurdo, Palmer, and offshore anchorages in Antarctica
note: few ports or harbors exist on the southern side of the
Southern Ocean; ice conditions limit use of most of them to short
periods in midsummer; even then some cannot be entered without
icebreaker escort; most antarctic ports are operated by government
research stations and, except in an emergency, are not open to
commercial or private vessels; vessels in any port south of 60
degrees south are subject to inspection by Antarctic Treaty
observers (see Article 7)

Transportation - note:
Drake Passage offers alternative to transit through the Panama Canal
