Lewis Cliff
Lewis Cliff () is an irregular cliff, about long, extending south from Mount Achernar along the west side of Walcott Neve, Antarctica. It was named by the Advisory Committee on Antarctic Names for Richard E. Lewis, a U.S. Navy Aviation Electronics Technician Aviation electronics technician (AT) is a US Navy enlisted rating or job specialty (often called MOS or AFSC by other services).

Mount Achernar
Mount Achernar () is a peak forming the northeast end of the MacAlpine Hills, on the south side of Law Glacier. Named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE) (1961–62) after the star Achernar used in fixing the survey baseline.AntacrticaStewart, J., 2011. ''Antarctica: An Encyclopedia,'' 2nd ed. Jefferson, North Carolina and London, McFarland & Company, Inc. 1771 pp. Late Permian buried forest Mount Achernar consists of the deeply eroded and glacially sculptured beds of sandstone, siltstone, shale, and coal of the Buckley Formation of the Beacon Supergroup. Exposed by the slopes of this mountain is a well known and studied late Permian buried forest consisting of numerous in situ fossil tree stumps. These silicified stumps are up to and height and in growth position. The tree rings on these stumps are well-preserved and exhibit narrow zones of latewood that represent a young, rapidly growing forest at latitudes of about 80° to 85 °S. These ...

Walcott Neve
Lennox-King Glacier is a large valley glacier, about long, draining Bowden Névé and flowing northeast between the Holland Range and the Queen Alexandra Range of Antarctica to enter Richards Inlet, Ross Ice Shelf. It was named by the New Zealand Geological Survey Antarctic Expedition (1959–60) for Lieutenant Commander James Lennox-King, Royal New Zealand Navy, leader at Scott Base, 1960.

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard E
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include "Richie", "Dick", "Dickon", " Dickie", " Rich", "Rick", " Rico", " Ricky", and more. Richard is a common English, German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish. Richard is cognate with variants of the name in other European languages, such as the Swedish "Rickard", the Catalan "Ricard" and the Italian "Riccardo", among others (see comprehensive variant list below).

Aviation Electronics Technician
Aviation electronics technician (AT) is a US Navy enlisted rating or job specialty (often called MOS or AFSC by other services). At the paygrade of E-9 (master chief petty officer), ATs merge with the aviation electrician's mate (AE) rating to become avionics technicians (AV). There has been talk of completely merging the two ratings, but as yet no definite plans have been announced. Aviation electronics technicians wear the specialty mark of a winged helium atom. Aviation electronics technicians (intermediate) perform intermediate level maintenance on aviation electronic components supported by conventional and automatic test equipment, including repair of weapons replaceable assemblies and shop replaceable assemblies and perform test equipment calibration/repair and associated test bench maintenance. Aviation electronics technicians (organizational) perform organizational level maintenance on aviation electronics systems, to include: communications, radar, navigation, antisubma ...

Operation Deep Freeze II
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. (There was an initial operation before Admiral Richard Byrd proposed 'Deep Freeze'). Given the continuing and constant US presence in Antarctica since that date, "Operation Deep Freeze" has come to be used as a general term for US operations in that continent, and in particular for the regular missions to resupply US Antarctic bases, coordinated by the United States military. Task Force 199 was involved. Prior to International Geophysical Year The U.S. Navy already had a record of earlier exploration in Antarctica. As early as 1839, Captain Charles Wilkes led the first U.S. Naval expedition into Antarctic waters. In 1929, Admiral Richard E. Byrd established a naval base at Little America I, led an expedition to explore further inland, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cliffs Of The Ross Dependency
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
