Antartica Photos
Antarctica
is the last continent. Almost totally covered with ice and with
temperatures far below zero, it hardly seems like an inviting tourist
destinations.
Indeed, you are unlikely to find anything like sun, sea and sandy beaches
on Antarctica. But you'll find a unique and exciting environment, and
traveling like you will not find it anywhere else.
The Southern Lands consist of two archipelagos, Iles Crozet and Iles
Kerguelen, and two volcanic islands, Ile Amsterdam and Ile Saint-Paul.
They contain no permanent inhabitants and are visited only by researchers
studying the native fauna. The Antarctic portion consists of "Adelie
Land," a thin slice of the Antarctic continent discovered and claimed by
the French in 1840.
There's no indigenous populations, although the islands are often
inhabitated by teams of researchers which study the local fauna.Antarctica is the coldest place on earth. Weather fronts rarely
penetrate far into the continent, leaving the center cold and dry. There
is little precipitation over the continent, but ice there can last for
extended time periods. Nearly all of Antarctica is covered by an ice
sheet that is, on average, 2.5 kilometers thick.
At the edge of the continent, strong katabatic winds off the polar
plateau often blow at storm force. In the interior, however, windspeeds
are often moderate.
Depending on the latitude, long periods of constant darkness, or constant
sunlight, mean that climates familiar to humans are not generally
available on the continent. |
The continent of Antarctica is located mostly south of the Antarctic
Circle, surrounded by the Southern Ocean. Physically Antarctica is
divided in two by mountains close to the neck between the Ross Sea and
the Weddell Sea. The portion of the continent west of the Weddell Sea and
east of the Ross Sea is called Western Antarctica and the remainder
Eastern Antarctica, since they correspond roughly to the eastern and
western hemispheres relative to the Greenwich meridian. Western
Antarctica is covered by the West Antarctic Ice Sheet.
It is usually estimated that at a given time there are at least 1,000
people living in Antarctica. This varies considerably with season.
Generally, stations use their home country's time zone, but not always;
where known, a base's UTC offset is listed. Although Antarctica has no
permanent residents, a number of governments maintain permanent research
stations throughout the continent. Many of the stations are staffed
around the year.
