Britannia Range (Antarctica)
The Britannia Range () is a range of mountains bounded by the Hatherton Glacier and Darwin Glacier (Antarctica), Darwin Glacier on the north and the Byrd Glacier on the south, westward of the Ross Ice Shelf in Antarctica. Exploration and naming The Britannia Range was discovered by the British National Antarctic Expedition (1901–04) under Robert Falcon Scott. It was named after HMS ''Britannia'', a vessel utilized as the Britannia Royal Naval College in England, which had been attended by several officers of Scott's expedition. Location The Britannia Range is east of the Antarctic Plateau. It is south of the Darwin Mountains and the Cook Mountains, which are north of the Hatherton Glacier and the Darwin Glacier (Antarctica), Darwin Glacier. At the mouth of the Darwin Glacier the range adjoins the Gawn Ice Piedmont, which extends into the Ross Ice Shelf to the east. The Byrd Glacier flows northeast past the south side of the Gawn Ice Piedmont. It divides the Britannia Range f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hatherton Glacier
The Darwin Glacier () is a large glacier in Antarctica. It flows from the polar plateau eastward between the Darwin Mountains and the Cook Mountains to the Ross Ice Shelf. The Darwin and its major tributary the Hatherton are often treated as one system, the Darwin–Hatherton. Early exploration and naming The lower part of the glacier was mapped by the British National Antarctic Expedition, 1901–04 (BrNAE), and the whole area traversed by New Zealand parties of the Commonwealth Trans-Antarctic Expedition (1956–58). The glacier was named in association with the Darwin Mountains. Glaciology The Darwin Glacier flows relatively slowly compared to other glaciers in the Transantarctic Mountains, at less than per year. There are small scale fluctuations due to daily tidal cycles downstream from its grounding line. During the Last Glacial Maximum (LGM) the Antarctic ice sheet expanded, forming grounded ice in the Ross Sea. This would cause the ice streams flowing into the Ross S ...

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic 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 Climate of Antarctica#Precipitation, 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 temperature recorded on Earth, lowest measured temperature on Earth, . The coastal regions can reach temperatures over in the ...

Mount Quackenbush
Hughes Basin () is a large basinlike névé which is bounded except to the south by the Ravens Mountains, Mount Henderson, Mount Olympus and Mount Quackenbush. The feature is long and the ice surface descends north–south from near Mount Olympus to near Darnell Nunatak, where there is discharge to Byrd Glacier. Name Hughes Basin was named after Terence J. Hughes of the Department of Geological Sciences and Institute of Quaternary Studies, University of Maine, Orono, who made an intensive study of the Byrd Glacier, 1978-79, entailing photogrammetric determination of the elevation of the ice surface and its velocity, radio-echo sounding from LC-130 aircraft, and ground survey from fixed stations close to Byrd Glacier and moving stations on the glacier itself. Location Hughes Basin is a large circular feature in the southwest of the Britannia Range to the south of Mount Henderson.

Mount Olympus
Mount Olympus (, , ) is an extensive massif near the Thermaic Gulf of the Aegean Sea, located on the border between Thessaly and Macedonia (Greece), Macedonia, between the regional units of Larissa (regional unit), Larissa and Pieria (regional unit), Pieria, about southwest from Thessaloniki. Mount Olympus has 52 peaks and deep gorges. The highest peak, Mytikas ( ''Mýtikas''), meaning "nose", rises to and is the highest peak in Greece, and one of the highest peaks in Europe in terms of topographic prominence. In Greek mythology, Olympus is the home of the List of Greek deities, Greek gods, on Mytikas peak. The mountain has exceptional biodiversity and rich flora (plants), flora. It has been a National parks of Greece, National Park, the first in Greece, since 1938. It is also a Man and the Biosphere Programme, World Biosphere Reserve.

Névé
Névé is a young, granular type of snow which has been partially melted, refrozen and compacted, yet precedes the form of ice. This type of snow can contribute to glacier formation through the process of ''nivation''. Névé that survives a full season of ablation turns into firn, which is both older and slightly denser. Firn eventually becomes glacial ice – the long-lived, compacted ice that glaciers are composed of. Glacier formation can take years to hundreds of years, depending on freeze-thaw factors and snow-compaction rates. Névé is annually observed in skiing slopes, and is generally disliked as an icy falling zone. Névé has a minimum density of 500 kg/m3, which is Density#Water, roughly half of the density of liquid water at 1 Atmosphere (unit), atm. Névé can also refer to the Alpine climate, alpine region in which snowfall accumulates, becomes névé, and feeds a glacier. See also * Suncup (snow), Suncup Notes External links * Névés, ...
