Exploring the obscure continent, an explorer from America showed us how isolated Antarctica really is. Antarctica is reportedly nearly five million square miles in area. Curiously enough, this land is almost completely covered by the world?s largest ice mass. 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. With the exception of certain mountain peaks of the highest elevation and a few sections of volcanic rock at the coast, the ice covers the entire continent. As a person looking for antarctic cruise you should visit that site.
Moving as a glacier to the sea, the ice travels in valleys between the high mountains. Rising an impressive eight to ten thousand feet above sea level, the central plateau is a huge land feature. The South Pole is found on it.
Geographical areas to the north lend their names to the four quadrants into which Antarctica has been divided. Therefore, there are the African, Pacific, American and sectors. No official explorations of the African and Pacific quadrant coastlines have been undertaken. Just a tiny portion of the American sector’s coastal area has been investigated, though the sector, and its Ross Sea region, has been the subject of relatively thorough exploration.
Ross Sea serves as the eastern boundary of the quadrant, which spans west to Queen Mary Land to include South Victoria Land, King George V Land, Oates Land, Adelle Land and Wilkes 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. This site teaches you about trips to antarctica.
The barrier?s ice cliffs have formed a natural bay, called the Bay of Whales. The explorer chose to set up his base camp in this area, which is actually on the barrier. Ross Island is perched at the westernmost point of the barrier, and features a pair of volcanoes, Mount Erebus and Mount Terror. From King Edward VII Land to the Ross Sea, the barrier travels for 400 miles. It is over 400 miles wide from the sea to the mountains that flank the polar ice route.
The barrier is the largest ice shelf in the world and this formation of shelf ice is unique to 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. Traveling up for lengths of up to 100 miles, and through channels of between five and fifteen miles in width, ice still comes to the Ross Sea. Scientists argue about whether the barrier floats or rests on the sea floor.
The Ross Sea also serves as the Pacific quadrant’s western boundary. An area here called King Edward VII land sports impressive rock outcroppings. Seeing the Scott Nunataks and the Alexandra Mountains, was a great reward for his first long flight from the Bay of Whales. This flight also allowed him to map out fourteen new mountain tops and an island. He saw land no one else had ever spotted. Subsequent trips provided greater information about the area and offered geographers the possibility of finally and specifically delineating the Pacific quadrant’s coastal region.
Many explorers have visited the American quadrant’s Coats Land, Charcot Land and Graham Land, in addition to the Weddell sea area. Finding out that Graham Land is not really part of the continent, but rather a separate island, was the result of explorations in flight. Geographers discuss if the continent should be divided. Adding further evidence to the question is the fact that the Ross Sea in the Quadrant is sitting almost directly across from the Weddell Sea in the American Quadrant.
Scientific research is unlimited in Antarctica. Geographers want to finish mapping the coastline. Then they can finalize the mountain ranges and polar plateau.
Geologist look to the land below the ice for exploration. They want to study the glaciers and how they?ve affected Antarctica?s land.
