Bertrab Nunatak
Bertrab Nunatak is a nunatak on the southern side of Lerchenfeld Glacier and about west-south-west of the Littlewood Nunataks. It has been described as "a bare rock about 1,739 feet high hatforms the southern entrance point of the uke ErnstBay."Sailing Directions for Antarctica (1960).

Nunatak
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lerchenfeld Glacier
Lerchenfeld Glacier (german: Lerchenfeldgletscher, ) is a glacier flowing in a west-northwesterly direction between Bertrab Nunatak and the Littlewood Nunataks in Antarctica. It coalesces with the southern flank of Schweitzer Glacier before the combined flow discharges into the head of Vahsel Bay. The glacier was discovered by the Second German Antarctic Expedition, 1911–12, under Wilhelm Filchner, who named this feature for Count Hugo von und zu Lerchenfeld-Köfering, a supporter of the expedition.

Littlewood Nunataks
The Littlewood Nunataks () are a group of four lichen-covered nunataks, rising to about between Schweitzer Glacier and Lerchenfeld Glacier, on the Luitpold Coast of Antarctica. The nunataks are brick red in color. They were discovered and first roughly charted by the Second German Antarctic Expedition, 1911–12, under Wilhelm Filchner. They were visited by helicopter from the icebreaker on January 28, 1959, by John C. Behrendt of the United States Geological Survey, and Lieutenant Erickson, U.S. Navy, and were named by Behrendt after oceanographer William H. Littlewood of the U.S. Navy Hydrographic Office, who worked in this and adjacent parts of the Weddell Sea area during Operation Deep Freeze Operation Deep Freeze (OpDFrz or ODF) is codename for a series of United States missions to Antarctica, beginning with "Operation Deep Freeze I" in 1955–56, followed by "Operation Deep Freeze II", "Operation Deep Freeze III", and so on.

Second German Antarctic Expedition
The Second German Antarctic Expedition of 1911–1913 was led by Wilhelm Filchner in the exploration ship . Its principal objective was to determine whether the Antarctic continent comprised a single landmass rather than separated elements, and in particular whether the Weddell Sea and Ross Sea were connected by a strait. In addition, an extensive programme of scientific research was undertaken. The expedition failed to establish a land base, and the ship became beset in the Weddell Sea ice, drifting north for eight months before reaching open water. The expedition was marred by considerable disagreement and animosity among its participants, and broke up in disarray. The expedition secured the patronage of Luitpold, Prince Regent of Bavaria, who formed a fundraising committee which organised, among other activities, a public lottery. After leaving Germany early in May 1911, the expedition carried out a thorough oceanographic survey of the Atlantic Ocean before arriving in South ...

Wilhelm Filchner
Wilhelm Filchner (13 September 1877 – 7 May 1957) was a German army officer, scientist and explorer. He conducted several surveys and scientific investigations in China, Tibet and surrounding regions, and led the Second German Antarctic Expedition, 1911–13. As a young military officer, Filchner gained an early reputation for dash and daring, following his travel exploits in Russia and the Pamir Mountains range. After further technical studies, he developed expertise in geography and geophysics, before leading a major scientific survey in Tibet and western China in 1903–05. In 1909 he was appointed to organise and lead the forthcoming German expedition to the Antarctic, with both scientific and geographical objectives involving extensive exploration of the continent's interior. During the expedition his ship became trapped in the Weddell Sea ice, drifting for eight months and preventing Filchner from establishing a land base, thus failing in its main objective.
