Ports and harbors:
there are no developed ports and harbors in Antarctica; most coastal stations have offshore anchorages, and supplies are transferred from ship to shore by small boats, barges, and helicopters; a few stations have a basic wharf facility; US coastal stations include McMurdo (77 51 S, 166 40 E), Palmer (64 43 S, 64 03 W); government use only except by permit (see Permit Office under "Legal System"); all ships at port are subject to inspection in accordance with Article 7, Antarctic Treaty; offshore anchorage is sparse and intermittent; relevant legal instruments and authorization procedures adopted by the states party to the Antarctic Treaty regulating access to the Antarctic Treaty area, to all areas between 60 and 90 degrees of latitude South, have to be complied with (see "Legal System") (2004)
Airports:
there are no developed public access airports or landing facilities; 30 stations, operated by 16 national governments party to the Antarctic Treaty, have restricted aircraft landing facilities for either helicopters or fixed-wing aircraft; commercial enterprises operate two additional aircraft landing facilities; helicopter pads are available at 27 stations; runways at 15 locations are gravel, sea-ice, blue-ice, or compacted snow suitable for landing wheeled, fixed-wing aircraft; of these, one is greater than 3 km in length, six are between 2 km and 3 km in length, three are between 1 km and 2 km in length, three are less than 1 km in length, and two are of unknown length; snow surface skiways, limited to use by ski-equipped, fixed-wing aircraft, are available at another 15 locations; of these, four are greater than 3 km in length, three are between 2 km and 3 km in length, two are between 1 km and 2 km in length, two are less than 1 km in length, and four are of unknown length; aircraft landing facilities generally subject to severe restrictions and limitations resulting from extreme seasonal and geographic conditions; aircraft landing facilities do not meet ICAO standards; advance approval from the respective governmental or nongovernmental operating organization required for using their facilities; landed aircraft are subject to inspection in accordance with Article 7, Antarctic Treaty; guidelines for the operation of aircraft near concentrations of birds in Antarctica were adopted in 2004; relevant legal instruments and authorization procedures adopted by states party to the Antarctic Treaty regulating access to the Antarctic Treaty area, that is to all areas between 60 and 90 degrees of latitude South, have to be complied with (see information under "Legal System"); an Antarctic Flight Information Manual (AFIM) providing up-to-date details of Antarctic air facilities and procedures is maintained and published by the Council of Managers of National Antarctic Programs (2004 est.)
