Map Of Antarctica
The huge land mass at the bottom of the world is little known and some, including an American explorers has focused some attention upon this isolated place. You can experience the world’s largest ice mass when visiting Antarctica.It nearly covers the continent’s five million square acres. The thickness of this ice sheet isn’t really known.Some scientists suggest it may be 2000 feet thick, others say it is much thicker. All of the continent is covered by the ice sheet, with the exception of the tallest mountain summits and certain coastal deposits of volcanic rock.
The valleys between the high mountains serve as a highway for the enormous glaciers as ice moves down to the sea. Mountainous regions serve as a buffer for the expansive central plateau on which the South Pole is found, and which rises 8,000 to 10,000 higher than sea level.

Antarctica has been divided into four sections which have been named for areas to the north. More specifically, there are the African, American, Pacific and quadrants. No official explorations of the African and Pacific quadrant coastlines have been undertaken. Containing the Ross Sea sector, the quadrant has been explored the most; the American quadrant coast has been investigated a little.
The quadrant lies between the Ross Sea on the east and Queen Mary Land on the west, and includes the areas designated as Adelle Land, South Victoria Land, Wilkes Land, Oates Land and King George V Land. The Ross Barrier forms a rim on the western Ross Sea.This is a huge sheet of shelf ice that extends over about 160 thousand square miles.
The barrier region, close to the Bay of Whales, features a harbor on the edge of the ice at the commencement of the shelf, where the adventurer established his exploration launching point. Mount Terror and Mount Erebus are the two volcanoes that fill Ross Island.The island is located at the western end of the barrier. Spanning over Ross Sea to King Edward VII land, the barrier is over 400 miles in length. It is 400 miles wide. Go to this site for further information on antarctica trip.
The barrier is shelf ice, as can only be found in Antarctica.This barrier was made when glaciers came down the mountains and ran into the Ross Sea. Glaciers still send ice to the sea, via channels that range in width from one to five miles.One such channel is one hundred feet long.It is unsettled whether the barrier is floating or if it is resting on the sea bottom.
The Ross Sea borders the Pacific Quadrant, as well.It is near here that fantastic rock outcroppings can be seen in King Edward VII land.During his first long flight from the Bay of Whales, the explorer was able to see the Scott Nunataks and the Alexandra Mountains. He was able to map fourteen new mountain peaks, as well as an island and saw hinterland that had yet to be seen. The information gathered by his flights has proved invaluable, and may even let geographers finally create a clear map of the Pacific quadrant coastline.
Several explorers have been interested in the sectors of Coats Land, Graham Land and Charcot Land, all part of the American quadrant in the Weddell Sea area. Flights over Graham Land discovered that is truly was not connected to the continent, but is an island separate from the land mass. Of major geographical concern is that the continent itself could very well be divided. The American quadrant’s Weddell Sea is just about opposite the quadrant’s Ross Sea.
Antarctica offers the planet an area of unlimited scientific research. Providing a picture of the mountain ranges and the polar plateau to a geographer along with determining a true chart of the coastal areas is the goal of all the geographers working here.
Geologists also look to understand the structure of the land beneath the ice, as well as examine the evidence that has been gleaned from the glaciers as they study how the glaciers affect the land.
