Ameghino Gully
Ameghino Gully () is a gully running east–west through the outcrops on the west side of Longing Peninsula, Nordenskjold Coast, Antarctica. The name derives from Refugio Ameghino, the Argentine refuge situated on the southwest side of Longing Gap and named in turn after Florentino Ameghino, Argentine geologist and anthropologist. Named by the United Kingdom Antarctic Place-Names Committee in 1990. References * Valleys of Graham Land Nordenskjöld Coast {{NordenskjöldCoast-geo-stub ...

Gully
A gully is a landform created by running water, mass movement, or commonly a combination of both eroding sharply into soil or other relatively erodible material, typically on a hillside or in river floodplains or terraces. Gullies resemble large ditches or small valleys, but are metres to tens of metres in depth and width and are characterised by a distinct 'headscarp' or 'headwall' and progress by headward (i.e. upstream) erosion. Gullies are commonly related to intermittent or ephemeral water flow usually associated with localised intense or protracted rainfall events, or snowmelt. Gullies can be formed and accelerated by cultivation practices on hillslopes (often gentle gradient) in farmland, and they can develop rapidly in rangelands from existing natural erosion forms subject to vegetative cover removal and livestock activity. Etymology The earliest known usage of the term is from 1657. It originates from the French word ''goulet'', a diminutive form of ''goule'' which m ...

Longing Peninsula
Cape Longing () is a rocky cape on the east coast of Graham Land, Antarctica, forming the south end of a large ice-covered promontory which marks the west side of the south entrance to Prince Gustav Channel. It was discovered by the Swedish Antarctic Expedition under Otto Nordenskiöld in 1902, and so named by him because from the position of his winter hut on Snow Hill Island the cape lay in the direction of his "land of longing" which he was anxious to explore. Cape Longing is the tip of Longing Peninsula (), which is long and situated at the northeast end of Nordenskjöld Coast where it separates the Larsen Ice Shelf from the Prince Gustav Ice Shelf. It was roughly charted by Nordenskiöld, and named after the cape by the UK Antarctic Place-Names Committee (UK-APC) following British Antarctic Survey geological work in the area in 1987–88. Longing Gap () is a constriction in the promontory north of Cape Longing, where the land narrows to and forms a low isthmus. The gap is u ...

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern 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 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 measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Florentino Ameghino
Florentino Ameghino (born Giovanni Battista Fiorino Giuseppe Ameghino September 19, 1853 – August 6, 1911) was an Argentine naturalist, paleontologist, anthropologist and zoologist, whose fossil discoveries on the Argentine Pampas, especially on Patagonia, rank with those made in the western United States during the late 19th century. Along with his two brothers –Carlos and Juan– Florentino Ameghino was one of the most important founding figures in South American paleontology. From 1887 until his death, Ameghino was passionately devoted to the study of fossil mammals from Patagonia, with the valuable support of his brother Carlos Ameghino (1865–1936) who, between 1887 and 1902, made 14 trips to that region, where he discovered and collected numerous fossil faunas and made important stratigraphic observations which helped to support his journal Ameghiniana. Biography Ameghino was born on September 19, 1853 in Tessi, an hamlet of Moneglia, a municipality of Liguria in Ita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Kingdom Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive features * Anckorn Nunataks, named after J. F. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valleys Of Graham Land
A valley is an elongated low area often running between hills or mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage now taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally. For ...
