Transantarctic Mountains Antarctica: geology, sea, Ross Island
The Transantarctic Mountains are a mountain range located in Antarctica that develop between Cape Adare, which is located north of Victoria Land, and Coats Land for a length of about three thousand five hundred kilometers.
General information about the Transantarctic Mountains
They are part of these mountains also smaller hills including those of Horlick, Thiel, Pensacola, Shackleton and Theron. The mountain ranges of the Antarctic Peninsula are commonly assimilated to the Transantarctic Mountains.
Lake Fryxell, located in the Transantarctic Mountains, is formed by water generated by melting glaciers. The Transantarctic Mountains with the crossing of the continent from the Ross Sea to the Weddell Sea reach heights that go beyond the five hundred meters of sea level with peaks mostly covered with ice.
Nearby Bay are the McMurdo Dry Valleys of McMurdo, being ice-free valleys and little rainy phenomena, they are an exception from the environmental point of view than the rest of the continent.
The highest mountain of the Transantarctic Mountains is the Mount Kirkpatrick with its 4,528 m altitude. Cape Adare, where many penguins live, separates the Ross Sea by the Southern Ocean and its hinterland are the Admiralty Mountains famous for being one of the landing during the expeditions in Antarctica.
The region of Antarctica called Victoria Land is located in the south of New Zealand.
The Coats Land is instead along the east coast of the Weddell Sea.
The Ross Sea is located between Victoria Land and Marie Byrd Land.
Because of the extremely cold temperatures a part of the surface that exceeds half of the total is perpetually covered by a sheet of ice of generous thickness which is also called barrier of Ross with an area of about half a million square kilometers. This sea was named in honor of the discoverer James Clark Ross.
Compared to the Ross Sea is located to the west of Ross Island with the active volcano Mount Erebus while to the east, nestled in a cove, lies the Bay of McMurdo, that during the Antarctic summer it is a natural harbor ice-free.
Because of strong storms are formed in the sea polynas that are large areas of water where the ice surface has opened the possibility of giving nourishment to the penguins of the area.
