Dipboye Cirque
Dipboye Cirque () is a cirque on the south side of the Olympus Range between Apollo Peak and Mount Electra in the McMurdo Dry Valleys. The cirque opens south to the Labyrinth. It was named by the Advisory Committee on Antarctic Names (2004) after Richard L. Dipboye 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 ..., PHI helicopter pilot with the United States Antarctic Program in eight consecutive field seasons from 1996–2003.

Cirque
A (; from the Latin word ') is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic , meaning a pot or cauldron) and (; ). A cirque may also be a similarly shaped landform arising from fluvial erosion. The concave shape of a glacial cirque is open on the downhill side, while the cupped section is generally steep. Cliff-like slopes, down which ice and glaciated debris combine and converge, form the three or more higher sides. The floor of the cirque ends up bowl-shaped, as it is the complex convergence zone of combining ice flows from multiple directions and their accompanying rock burdens. Hence, it experiences somewhat greater erosion forces and is most often overdeepened below the level of the cirque's low-side outlet (stage) and its down-slope (backstage) valley. If the cirque is subject to seasonal melting, the floor of the cirque most often forms a tarn (small lake) behind a dam, which marks the down ...

Olympus Range
Olympus Range () is a primarily ice-free mountain range of Victoria Land, Antarctica, with peaks over , between Victoria and McKelvey Valleys on the north and Wright Valley on the south. It was mapped by the Victoria University of Wellington Antarctic Expedition, 1958–59, and named for the mythological home of the Greek gods. Peaks in the range are named for figures in Greek mythology. Further reading * I.B. Campbell, G.G.C.

McMurdo Dry Valleys
The McMurdo Dry Valleys are a row of largely snow-free valleys in Antarctica, located within Victoria Land west of McMurdo Sound. The Dry Valleys experience extremely low humidity and surrounding mountains prevent the flow of ice from nearby glaciers. The rocks here are granites and gneisses, and glacial tills dot this bedrock landscape, with loose gravel covering the ground. It is one of the driest places on Earth and has not seen rain for nearly two million years. The region is one of the world's most extreme deserts, and includes many features including Lake Vida, a saline lake, and the Onyx River, a meltwater stream and Antarctica's longest river. Although no living organisms have been found in the permafrost here, endolithic photosynthetic bacteria have been found living in the relatively moist interior of rocks, and anaerobic bacteria, with a metabolism based on iron and sulfur, live under the Taylor Glacier. The valleys are located within the McMurdo Valleys Antarc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Labyrinth (Antarctica)
The Labyrinth () is an extensive flat upland area which has been deeply eroded, at the west end of Wright Valley, in Victoria Land, Antarctica. It was so named by the Victoria University of Wellington Antarctic Expedition (1958–59) because the eroded dolerite of which it is formed gives an appearance of a labyrinth.

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 L
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).

Petroleum Helicopters International
Petroleum Helicopters International, Inc. (PHI), is an American commercial helicopter operator, founded in 1949, by Robert L. Suggs. The company is based in Lafayette, Louisiana and provides service for the oil and gas industry, aeromedical services, pilot training and aircraft maintenance. In October 2017, PHI acquired Helicopters (NZ) from HNZ Group. On March 15, 2019, the company filed for Chapter 11 bankruptcy.

United States Antarctic Program
The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the Antarctica continent. Founded in 1959, the USAP manages all U.S. scientific research and related logistics in Antarctica as well as aboard ships in the Southern Ocean. United States Antarctic Program The United States established the U.S. Antarctic Research Program (USARP) in 1959—the name was later changed to the U.S. Antarctic Program—immediately following the success of the International Geophysical Year (IGY). Today, the National Science Foundation (NSF) has a Presidential Mandate to manage the United States Antarctic Program, through which it operates three year-round research stations and two research vessels, coordinates all U.S. science on the southernmost continent, and works with other federal agencies, the U.S. military, an ...

Landforms Of Victoria Land
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features.
