A Written Portrayal Of Antarctica
By Advisor. Filed in Florida |
The journey of an American adventurer to Antarctica has sparked heightened interest in the remote and mysterious part of the world. Antarctica sports the world’s largest ice mass.It almost covers the five million square miles of the continent. Scientists argue about just how thick the ice sheet is.Some have posited a figure of 2000 feet; others say this is too thin. All of the solid land, minus the most tall mountains and some of the coastal areas, have been covered in ice.
Moving as a glacier to the sea, the ice travels in valleys between the high mountains. The mountain ranges serve as the underpinnings of the expansive central plateau, which ranges from 8,000 to 10,000 feet above sea level and where the South Pole is located.

Antarctica has been mapped into four distinct areas; these are named for geographical areas to the north. They’ve been identified as the African,, Pacific and American quadrants. The coasts of both the African and Pacific quadrants are substantially unexplored. Just a small section of the American quadrant’s coast has been explored, but the quadrant is very well known.It includes the Ross Sea area.
Queen Mary Land serves as the westward border of the quadrant and the Ross See is the eastern border.It also has South Victoria Land, Oates Land, King George V Land, Adelle Land and Wilkes Land. You’ll find a big sheet of shelf ice, which is about 160 thousand miles square, called the Ross Barrier, on 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. Mount Terror and Mount Erebus are two volcanoes which cover most of the Ross Island at the western end of the barrier. Exceeding four hundred miles long, is the barrier which reaches across the Ross Sea to King Edward VII land. From the ocean to the mountainous regions, along the polar course, it is 400 miles wide.

This barrier is the biggest example of shelf ice, which is singular to Antarctica. Glaciers coming from the mountains met the Ross Sea and this created the barrier.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.There’s still an outstanding question as to whether the Barrier sits on the bottom or rests on the ice.
There’s a deposit of rocks extending outward in King Edward VII land which is one of the boundaries along with the Ross Sea for the Pacific Quadrant. Flying in his first lengthy 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 flights gathered lots of data about the area, and might let geographers create a definitive map of the Pacific quadrant’s coast.
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. Determining that Graham Land is actually a separate island from Antarctica was the result of another flying explorer attempting to evaluate the entire continent over time. Those involved in geography wonder if the continent should be divided. The quadrant’s Ross Sea lies opposite the American quadrant’s Weddell Sea.
Antarctica offers the planet an area of unlimited scientific research. 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 would like to further study the ice-covered land.They also want to find out more about how the glaciers affect the land.
