Mason Nunatak
Mason Nunatak () is a nunatak, which 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. This particular nunatuk is long at the northwest end of the Meteorite Hills and the Darwin Mountains of Antarctica. Mason Nunatuk was named after Brian Harold Mason of the Department of Mineral Sciences, Smithsonian Institution, Washington, D.C.

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 can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meteorite Hills
The Meteorite Hills () are a group of hills, long, forming the western portion of the Darwin Mountains in Antarctica. The hills are located between the heads of Darwin Glacier and Hatherton Glacier. The name was proposed by John O. Annexstad of the Meteorite Working Group at the Johnson Space Center, Houston, Texas, in association with field work carried out in this vicinity by the Antarctic Search for Meteorites, led by William A. Cassidy of the University of Pittsburgh The University of Pittsburgh (Pitt) is a public state-related research university in Pittsburgh, Pennsylvania. The university is composed of 17 undergraduate and graduate schools and colleges at its urban Pittsburgh campus, home to the universit ..., during the 1978–79 season.

Brian Harold Mason
Brian Harold Mason (18 April 1917 – 3 December 2009) was a New Zealand geochemist and mineralogist who was one of the pioneers in the study of meteorites. He played a leading part in understanding the nature of the Solar System through his studies of meteorites and lunar rocks. He also examined and classified thousands of meteorites collected from Antarctica. Life Mason was born in Port Chalmers, Dunedin, in 1917 and was brought up in Christchurch, New Zealand. He was educated at Christchurch Boys' High School and studied geology and chemistry at Canterbury University College, graduating MSc with first-class honours in 1939. In November he left for Norway to work towards a doctorate, arriving in January 1940, but along with a colleague who held a British passport fled to Sweden in May following Operation Weserübung, the German invasion of Norway. In 1943, he completed a PhD in geochemistry at the University of Stockholm under Victor Goldschmidt and left the country for Brit ...

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 ...
