50 Amazing Facts About Antarctica

Antarctica Ice Sheet & Mountains
NASA scientists snapped this pristine shot while flying over Antarctica in December 2012. The researchers surveyed the ice sheet and mountains from a U.S. Air National Guard LC-130 aircraft.Next week, NASA's Operation IceBridge will kick off a new season of monitoring ice sheets, glaciers and sea ice. This year, the mission will be stationed in Antarctica for the first time, enabling researchers to conduct more science on longer flights over the icy continent. Previously, Operation IceBridge flights took off from Punta Arenas in southern Chile. [Related Images: NASA's IceBridge in Action Over Antarctica]

Introduction

cold places, coolest place

The coldest temperature ever recorded on Earth was minus 128.56 degrees Fahrenheit (minus 89.2 degrees Celsius), registered on July 21, 1983, at Antarctica's Vostok station.

It's seriously dry

The Dry Valleys of Antarctica are the driest place on Earth, with low humidity and almost no snow or ice cover.

There's a lot of wind

On average, Antarctica is the windiest continent. Winds in some places of the continent can reach 200 mph (320 km/h).

It's a big place

Antarctica is the fifth largest continent.

There's lots of ice

The Antarctic Ice Sheet is the largest single mass of ice on Earth.

Ninety-nine percent of Antarctica is covered by ice.

It stores a lot of fresh water

Antarctica is home to about 70 percent of the planet's fresh water, and 90 percent of the planet's freshwater ice.

It's melting

If the West Antarctic Ice Sheet melted entirely, it would raise global average sea levels by 16 feet (5 meters), according to some estimates.

The ice is thick

The average thickness of Antarctic ice is about 1 mile (1.6 kilometers).

It's bigger than the U.S.

Including its islands and attached floating plains of ice, Antarctica has an area of about 5.4 million square miles (14 million square kilometers), about one-and-a-half times the size of the United States.

The Ross Ice Shelf is the largest

The largest of Antarctica's ice shelves (floating tongues of ice) is the Ross Ice Shelf, which measures some 197,000 square miles (510,680 square kilometers), or 3.7 percent of the total area of Antarctica.
