An American’s exploration of Antarctica called attention to its remote and unknown nature. The world’s largest ice mass can be found in Antarctica.It almost covers the entire land mass of nearly five million miles. It is amazing as to how deep the ice covering is on this cold area with some estimating the ice at a depth of over 2,000 feet thick, although some think this is a conservative estimate. All of the solid land, minus the most tall mountains and some of the coastal areas, have been covered in ice.
The icy cover migrates toward the ocean as a coastal glacial extension, between mountain peaks and through depression areas. Rising above sea level at eight to ten thousand feet, the central plateau is huge and houses the South Pole.Contact this website if you require information on antarctic tours.
Antarctica has been separated into four quadrants which derive their names from lands to the north. You would know them as the African,, Pacific and American quadrants. There is virtually little evidence regarding the Pacific and African coasts of Antarctica. A very small area of the American quadrant coastline has been really investigated; the quadrant is far better known.It contains the Ross Sea sector.
The quadrant has the Ross Sea on its east, and then stretches west to Queen Mary Land.South Victoria Land, Oates Land, King George V Land, Adelle Land and Wilkes Land are all in the quadrant. The Ross Barrier, which measures about 160, 000 square miles, can be found in the mountainous area near the western rim of the Ross Sea.
This is where the explorer set up his base camp.He was near a naturally formed harbor called the Bay of Whales. Two volcanoes are found near the barrier’s end.They are Mount Terror and Mount Erebus.The barrier is over 400 miles long and crosses the Ross Sea to King Edward VII land. The width measured from the sea to the mountains skirting the polar route is 400 miles. Go to this site for further information on antarctica trip.
The barrier is shelf ice, as can only be found in Antarctica.It was created by glacier tongues which originated in the mountains and subsequently spread over the submerged area of Antarctica in the Ross Sea section. Ice still hits the Ross Sea from several glacial channels which range from five to fifteen miles in width.One is over a hundred miles long. Explorers are unsure if the Barrier floats or rests on the bottom of the ocean.
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 Scott Nunataks and the Alexandra Mountains greeted the explorer on his first long flight from the Bay of Whales. During his flights, he also found fourteen new mountain peaks, a new island and saw vast, unexplored lands. The flights gathered lots of data about the area, and may let geographers create a definitive map of the Pacific quadrant’s coast.
Many explorers have seen the American quadrants Weddell seal area, which cuts into the continent.There are also the Coats Land, Charcot Land and Graham Land areas here. Finding out that Graham Land is not really part of the continent, but rather a separate island, was the result of explorations in flight.Those involved in geography wonder if the continent should be divided. The Weddell Sea in the American quadrant is just about opposite the Ross Sea in the quadrant.
The research possibilities of Antarctica are basically limitless. A finished map of the coast line and mountain ranges, as well as the polar plateau are the geographers goal.
The geologist is very involved in learning the composition of the ice covered land and in the gathering of geological data from glacial moraines and rock outcroppings which aid in explaining the glaciology of the continent.
