The following are links that I found particularly interesting. The Seventh Continent - good photos and an interesting journal. English, as spoken in McMurdo - A listing of terminology. The Ice - A private page with up to date photos and an active discussion board.
Most people stop here as they head to Antarctica.
Antarctica Factbook - See what the CIA has to say about Antarctica. American Samoa Factbook - See what the CIA has to say about Pago Pago and American Samoa. McMurdo Sound - Excellent pictures of some of the flora and fauna of the McMurdo area. Time Channel - A useful site for understanding world time changes. The International Date Line - The International Date Line is confusing.
