Umber Island
Umber Island () is a rocky island, 2.4 km (1.5 miles) long, lying southwest of Kamhi Point and 10 km (6 miles) northwest of Dint Island lying within Lazarev Bay, off the west side of Alexander Island, Antarctica. The island was mapped from air photos taken by the Ronne Antarctic Research Expedition (RARE) in 1947–48, by Searle of the Falkland Islands Dependencies Survey in 1960, it was so named by the United Kingdom Antarctic Place-Names Committee because on the RARE photos the island appears in deep shadow cast by the Havre Mountains to the north.

Island
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kamhi Point
Kamhi Point ( bg, нос Камхи, ‘Nos Kamhi’ \'nos kam-'hi\) is the sharp rocky point on the northwest coast of Alexander Island in Antarctica projecting 450 m westwards into Lazarev Bay south of the terminus of Oselna Glacier. The feature is named after Rafael Moshe Kamhi (1870-1970), a leader of the Bulgarian liberation movement in Macedonia. Location Kamhi Point is located at , which is 19.17 km south-southeast of Cape Vostok, 8.8 km southeast of Buneva Point, 6.17 km northwest of Goleminov Point and 1 km northeast of Umber Island.

Dint Island
Dint Island is a rocky island, long. Probably first seen from the air by the United States Antarctic Service, 1939–41, it was first mapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960. It was so named by the UK Antarctic Place-Names Committee because a distinctive cirque makes a dent, or dint, on the south side of the island. Location Dint Island is located at () and lies off the west side of Alexander Island within Lazarev Bay. The island lies roughly 6 miles (10 km) southeast of Umber Island.

Lazarev Bay
Lazarev Bay is a rectangular bay, long and wide, which separates Alexander Island from Rothschild Island and is bounded on the south side by the Wilkins Ice Shelf, which joins the east portion of Rothschild Island and the west portion of Alexander Island (partially Cape Vostok, the Havre Mountains and the Lassus Mountains). Two minor islands, Dint Island and Umber Island, lie merged within the ice of the Wilkins Ice Shelf within Lazarev Bay. The north coast of Alexander Island was first seen from a great distance by the Russian expedition of 1821 under Fabian Gottlieb von Bellingshausen. The bay was first mapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960, and it was named by the UK Antarctic Place-Names Committee for Lieutenant Mikhail Petrovich Lazarev, second-in-command of Bellingshausen's expedition and commander of the sloop '' Mirnyy''.

Alexander Island
Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west.Stewart, J. (2011) ''Antarctic An Encyclopedia'' McFarland & Company Inc, New York. 1776 pp. . Alexander Island is about long in a north–south direction, wide in the north, and wide in the south. Alexander Island is the second-largest uninhabited island in the world, after Devon Island. History Alexander Island was discovered on January 28, 1821, by a Russian expedition under Fabian Gottlieb von Bellingshausen, who named it Alexander I Land for the reigning Tsar Alexander I of Russia.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ronne Antarctic Research Expedition
The Ronne Antarctic Research Expedition (RARE) was an expedition from 1947–1948 which researched the area surrounding the head of the Weddell Sea in Antarctica. Background Finn Ronne led the RARE which was the final privately sponsored expedition from the United States and explored and mapped the last unknown coastline on earth and determined that the Weddell Sea and the Ross Sea were not connected. The expedition included Isaac Schlossbach, as second in command, who was to have Cape Schlossbach named after him. The expedition, based out of Stonington Island was the first to take women to over-winter. Ronne's wife, Edith Ronne was correspondent for the North American Newspaper Alliance for expedition and the chief pilot Darlington took his wife.

United Kingdom Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive features * Anckorn Nunataks, named after J. F. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Havre Mountains
The Havre Mountains () are a large group of mountains forming the northwestern extremity of Alexander Island, Antarctica, extending in an east–west direction between Cape Vostok and the Russian Gap. They were first seen in 1821 by a Russian expedition under Fabian Gottlieb von Bellingshausen and re-sighted by the Belgian Antarctic Expedition, 1897–99. They were roughly charted by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, who named them for Le Havre, the French port from which the ''Pourquoi-Pas (1908), Pourquol Pas?'' sailed in 1908. The mountains were mapped in detail from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960.
