The name Antarctica is the Roman derivative of the Greek word meaning "opposite to the north." During the winter months in Antarctica, there are nearly 24 hours of daylight to explore the White Continent's varied wildlife, including the Adelie penguins pictured above. About 98% of Antarctica is covered by ice, which averages at least one mile in thickness. There are no permanent human residents, but anywhere from 1,000 to 5,000 people reside at the various research stations scattered across the continent throughout the year.
