What is the Antarctic?

One thing that confused us, and undoubtedly many others, was what exactly entailed “being in Antarctica”.

Fortunately, governmental decree and agreement has helped define that for us in the form of the Antarctic Treaty, which was put in force in 1961 by a coalition of countries.

It defines Antarctica as being all lands and ice shelves south of 60° South Latitude, which includes places as far north as the South Orkney Islands, where we’ll be tomorrow; Elephant Island, where we were today; and of course, the Antarctic Peninsula, where we were the three days prior.

The Antarctic circle, which is at 66° 33′ 39”, defines the region below (south of) which the sun will not set on the day of the winter solstice in December (summer in Antarctica), and will not rise on the day of the summer solstice in June (winter in Antarctica).

And finally, there’s the Subantarctic. This is the area north of 60° south latitude, north some degrees to include nearby islands, such as South Georgia Island (where we will be on Saturday for a week or so). There is no hard and fast definition of where the sub-Antarctic ends, with islands as far north as the Falkland Islands (where we will be in about 10 days) being included in the Subantarctic (or sub-Antarctic if you prefer).

Hope that clears it up! It certainly did for us.


GPS Tracking – Crossing the Antarctic Circle Southward

February 14th, 2010 at 4:33 pm (AST) by Jake Richter

Last night past midnight we crossed southward over the 66.33 degree south latitude line, but alas, we didn’t feel it. Spent much of the day in fog searching for a suitable landing site with penguin colonies. Found one mid-afternoon at Red Rocks Ridge – numerous groups of Adelie Penguins. Photos later.

For now, our GPS track from about 21:44 last night through the present. No idea where we’re going next except that it’s probably northwards along the Antarctic Peninsula.
