Reaching The Continent: A Map To Antarctica
The segregated nature of Antarctica has been shown by an American explorer. Estimations of the land mass of Antarctica are that it approaches 5,000,000 square miles, all underneath a continental ice sheet, which is the largest on Earth. According to some scientists, the ice sheet is 2000 feet thick. Other scientists argue it has to be much more thick. The very tallest mountain peaks and some land areas on the coast are the only areas to have escaped the ice. Visit this site for further information on antarctica cruises.
Like a glacier, the ice moves amid mountain peaks to the ocean. The South Pole is located on the huge central plateau. It juts above the ocean from eight to ten thousand feet.
Antarctica has been separated into four quadrants which derive their names from lands to the north. Therefore, there are the African, Pacific, American and sectors. The African and Pacific sectors have coastal areas which have gone essentially unexplored. Because it contains the Ross Sea sector, the quadrant has been pretty well looked into. The American quadrant coast has been looked at a little.
Wilkes Land, Adelle Land, King George V Land, Oates Land, and South Victoria Land, which have boundaries on the west by Queen Mary Land and the east by the Ross Sea encompasses the quadrant. There is a broad sheet of ice which covers over one hundred and sixty thousand square miles with mountains rising out of the Ross Barrier and the western rim of the Ross Sea. As a person looking for antarctica vacations you should visit that site.
This is where the American explorer has established his base camp, near the Bay of Whales, a naturally carved harbor in the ice cliffs of the barrier. Mount Erebus and Mount Terror are the two volcanoes that can be found at the end of the barrier. The barrier extends for a length in excess of 400 miles, from the Ross Sea to King Edward VII Land. At 400 miles in width, it stretches from the sea to the polar route mountains.
The barrier is a great example of shelf ice, which can only be seen in Antarctica. The barrier was made by sections of glaciers that traveled down from the mountains and then entered the sea in the Ross Sea area. Ice still travels through glacier channels, with can be between five and fifteen miles wide, to reach the Ross Sea. Some ice travels for over one hundred miles. There is still an outstanding question as to whether the Barrier sits on the bottom or rests on the ice.
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. The explorer first witnessed the Scott Nunataks and Alexandra Mountains when flying for the first time from the Bay of Whales. He discovered an island, placed fourteen peaks on the map of the territory and spotted the as yet unseen backcountry. Perhaps the later flights may assist scientist in establishing the coastline of the Pacific Quadrant and provide more information and knowledge regarding this territory.
A number of different explorers have been interested in new sectors which include Graham Land, Charcot Land, and Coats Land, all lying in the American Quadrant near the Weddell Sea area. One explorer flew over Graham Land and found it to be a separate island, not actually connected to the mainland. A major geographical issue is the chance that the continent could be split. The Weddell Sea in the American quadrant is across from the Ross Sea in the quadrant.
Of major geographical concern is that the continent itself could very well be divided.. Geographers are interested in gaining specific facts able to provide a through and precise mapping of the coastlines, and a thorough view of the mountains and plateau containing the South Pole.
Geologists want to be able to study the land hidden by the ice. They want to study how the glaciers have interacted with the land, too.
