Sennet Glacier
The Byrd Glacier () is a major glacier in Antarctica, about long and wide. It drains an extensive area of the Antarctic plateau, and flows eastward to discharge into the Ross Ice Shelf. Location The Byrd Glacier flows eastward between the Britannia Range to the north and the Churchill Mountains to the south. It discharges into the Ross Ice Shelf at Barne Inlet. Its mouth lies between Cape Kerr to the north and Cape Selborne to the south. The valley below the glacier used to be recognised as one of the lowest points not to be covered by liquid water on Earth, reaching below sea level. The glacier was named by the NZ-APC after Rear Admiral Richard E. Byrd, United States Navy, American Antarctic explorer. Mouth Barne Inlet A reentrant about wide occupied by the lower part of Byrd Glacier, lying between Cape Kerr and Cape Selborne on the west side of the Ross Ice Shelf.

Landsat
The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. It is a joint NASA / USGS program. On 23 July 1972, the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat 1 in 1975. The most recent, Landsat 9, was launched on 27 September 2021. The instruments on the Landsat satellites have acquired millions of images. The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance and education, and can be viewed through the U.S. Geological Survey (USGS) "EarthExplorer" website. Landsat 7 data has eight spectral bands with spatial resolutions ranging from ; the temporal resolution is 16 days. Landsat images are usually divided into scenes for easy downloading.

Glacier
A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land“Glacier, N., Pronunciation.” Oxford English Dictionary, Oxford UP, June 2024, https://doi.org/10.1093/OED/7553486115. Accessed 25 Jan. 2025. and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on ever ...

Nunatak
A nunatak (from Inuit language, Inuit ) 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 often form natural pyramidal peaks. Isolated nunataks are also called glacial islands, and smaller nunataks rounded by glacial action may be referred to as rognons. The word is of Greenlandic language, Greenlandic origin and has been used in English since the 1870s. Description The term ''nunatak'' is typically used in areas where a permanent ice sheet is present and the ridge protrudes 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 are isolated, they can also form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, hampering the formation of glacial ice on thei ...

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, ...
