Sabrina Coast
Sabrina Coast () is that portion of the coast of Wilkes Land, Antarctica, lying between Cape Waldron, at 115° 33' E, and Cape Southard, at 122° 05' E. John Balleny has long been credited with having seen land in March 1839 at about 117° E. The United States Exploring Expedition under Lt. Charles Wilkes approached this coast in February 1840 and indicated its general configuration as shown in part by "Totten High Land" on his 1840 chart. In 1931 the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Douglas Mawson Sir Douglas Mawson OBE FRS FAA (5 May 1882 – 14 October 1958) was an Australian geologist, Antarctic explorer, and academic. Along with Roald Amundsen, Robert Falcon Scott, and Sir Ernest Shackleton, he was a key expedition leader during ... saw what appeared to be land in this longitude about one degree farther south than that reported by Balleny and Wilkes. In recognition of Balleny's effort, Mawson retained the name of the cutter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wilkes Land
Wilkes Land is a large district of land in eastern Antarctica, formally claimed by Australia as part of the Australian Antarctic Territory, though the validity of this claim has been placed for the period of the operation of the Antarctic Treaty, to which Australia is a signatory. Geography Wilkes Land fronts on the southern Indian Ocean between Queen Mary Coast and Adelie Land, extending from Cape Hordern in 100°31' E to Pourquoi Pas Point, in 136°11' E. The region extends as a sector about 2600 km towards the South Pole, with an estimated land area of 2,600,000 km², mostly glaciated. Subdivisions It is further subdivided in the following coastal areas which can also be thought of as sectors extending to the South Pole: # Knox Land: 100°31' E to 109°16' E # Budd Land: 109°16' E to 115°33' E # Sabrina Land: 115°33' E to 122°05' E # Banzare Land: 122°05' E to 130°10' E # Clarie Land: (Wilkes Coast) 130° ...

United States Exploring Expedition
The United States Exploring Expedition of 1838–1842 was an exploring and surveying expedition of the Pacific Ocean and surrounding lands conducted by the United States. The original appointed commanding officer was Commodore Thomas ap Catesby Jones. Funding for the original expedition was requested by President John Quincy Adams in 1828; however, Congress would not implement funding until eight years later.

Ex. for short, or the Wilkes Expedition in honor of its next appointed commanding officer, United States Navy Lieutenant Charles Wilkes. The expedition was of major importance to the growth of science in the United States, in particular the then-young field of oceanography. During the event, armed conflict between Pacific islanders and the expedition was common and dozens of natives were killed in action, ...

British Australian New Zealand Antarctic Research Expedition
The British Australian (and) New Zealand Antarctic Research Expedition (BANZARE) was a research expedition into Antarctica between 1929 and 1931, involving two voyages over consecutive Austral summers. It was a British Commonwealth initiative, driven more by geopolitics than science, and funded by the United Kingdom, Australia and New Zealand. The leader of the BANZARE was Sir Douglas Mawson and there were several subcommanders (Captain K.N. MacKenzie, who replaced Captain John King Davis for the second summer) on board the RRS Discovery, the ship previously used by Robert Falcon Scott. The BANZARE, which also made several short flights in a small plane, mapped the coastline of Antarctica and discovered Mac. Robertson Land and Princess Elizabeth Land (which later was claimed as part of the Australian Antarctic Territory). The voyages primarily comprised an "acquisitive exploratory expedition", with Mawson making proclamations of British sovereignty over Antarctic lands at each o ...

Douglas Mawson
Sir Douglas Mawson OBE FRS FAA (5 May 1882 – 14 October 1958) was an Australian geologist, Antarctic explorer, and academic. Along with Roald Amundsen, Robert Falcon Scott, and Sir Ernest Shackleton, he was a key expedition leader during the Heroic Age of Antarctic Exploration. Mawson was born in England and came to Australia as an infant. He completed degrees in mining engineering and geology at the University of Sydney. In 1905 he was made a lecturer in petrology and mineralogy at the University of Adelaide. Mawson's first experience in the Antarctic came as a member of Shackleton's ''Nimrod'' Expedition (1907–1909), alongside his mentor Edgeworth David. They were part of the expedition's northern party, which became the first to attain the South Magnetic Pole and to climb Mount Erebus. After his participation in Shackleton's expedition, Mawson became the principal instigator of the Australasian Antarctic Expedition (1911–1914). The expedition explored thousand ...

Coasts Of Antarctica
The coast, also known as the coastline or seashore, is defined as the area where land meets the ocean, or as a line that forms the boundary between the land and the coastline. The Earth has around of coastline. Coasts are important zones in natural ecosystems, often home to a wide range of biodiversity. On land, they harbor important ecosystems such as freshwater or estuarine wetlands, which are important for bird populations and other terrestrial animals. In wave-protected areas they harbor saltmarshes, mangroves or seagrasses, all of which can provide nursery habitat for finfish, shellfish, and other aquatic species. Rocky shores are usually found along exposed coasts and provide habitat for a wide range of sessile animals (e.g. mussels, starfish, barnacles) and various kinds of seaweeds. Along tropical coasts with clear, nutrient-poor water, coral reefs can often be found between depths of . According to a United Nations atlas, 44% of all people live within 5 km (3.3mi) of ...
