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
