Obelya Glacier
Obelya Glacier ( bg, ледник Обеля, lednik Obelya, ) is the long and wide glacier on the east side of southern Sentinel Range in Ellsworth Mountains, Antarctica, situated south of Remington Glacier, and flowing southeastwards along the southwest side of Johnson Spur and east of Mount Benson to join Thomas Glacier. The glacier is named after the settlement of Obelya in Western Bulgaria, now part of the city of Sofia. Location Obelya Glacier is centred at . US mapping in 1961, updated in 1988.

Ellsworth Mountains
The Ellsworth Mountains are the highest mountain ranges in Antarctica, forming a long and wide chain of mountains in a north to south configuration on the western margin of the Ronne Ice Shelf in Marie Byrd Land. They are bisected by Minnesota Glacier to form the Sentinel Range to the north and the Heritage Range to the south. The former is by far the higher and more spectacular with Mount Vinson () constituting the highest point on the continent.Bockheim, J.G., Schaefer, C.E., 2015. ''Soils of Ellsworth Land, the Ellsworth Mountains''. In: Bockheim, J.G. (Ed.), ''The Soils of Antarctica. World Soils Book Series'', Springer, Switzerland, pp. 169–181. The mountains are located within the Chilean Antarctic territorial claim but outside of the Argentinian and British ones. Discovery The mountains were discovered on November 23, 1935, by Lincoln Ellsworth in the course of a trans-Antarctic flight from Dundee Island to the Ross Ice Shelf. He gave them the descriptive name Sentinel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Ellsworth Land
Ellsworth Land is a portion of the Antarctic continent bounded on the west by Marie Byrd Land, on the north by Bellingshausen Sea, on the northeast by the base of Antarctic Peninsula, and on the east by the western margin of the Filchner–Ronne Ice Shelf. It extends between 103°24'W and 79°45'W. The area west of 90°W is unclaimed, the area between 84°W and 90°W is claimed by Chile only, and the remainder by Chile and the United Kingdom as a part of the British Antarctic Territory. Eights Coast stretches between 103°24'W and 89°35'W, and Bryan Coast between 89°35'W and 79°45'W. It is largely a high ice plateau, but includes the Ellsworth Mountains and a number of scattered mountain groups: Hudson, Jones, Behrendt, Hauberg, Merrick, Sweeney and Scaife Mountains. This land lies near the center of the area traversed by American explorer Lincoln Ellsworth on an airplane flight during November–December 1935. It was named for him by the Advisory Committee on Antarct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Glacier
Thomas Glacier () is a roughly Z-shaped glacier which drains the southeast slopes of Vinson Massif and flows for 17 nautical miles (31 km) through the south part of the Sentinel Range, Ellsworth Mountains, leaving the range between Doyran and Petvar Heights south of Johnson Spur. The glacier was discovered by U.S. Navy Squadron VX-6 on photographic flights of December 14–15, 1959, and mapped by United States Geological Survey (USGS) from the photos. It was named by Advisory Committee on Antarctic Names (US-ACAN) for R. Admiral Charles W. Thomas, USCG, veteran of Antarctic expeditions in the 1950s.

Sentinel Range
The Sentinel Range is a major mountain range situated northward of Minnesota Glacier and forming the northern half of the Ellsworth Mountains in Antarctica. The range trends NNW-SSE for about and is 24 to 48 km (15 to 30 mi) wide. Many peaks rise over and Vinson Massif (4892 m) in the southern part of the range is the highest elevation on the continent.Sentinel Range. SCAR Composite Antarctic Gazetteer. Sentinel Range comprises a main ridge (featuring Vinson Massif in its southern portion) and a number of distinct heights, ridges and mountains on its east side, including (south to north) , [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remington Glacier
Remington Glacier is a steep glacier about long in Doyran Heights in the Sentinel Range of Ellsworth Mountains, Antarctica. It rises just north of McPherson Peak and flows east-southeast to debouch between the terminus of Hough Glacier and Johnson Spur. Background Discovered by U.S. Navy Squadron VX-6 on photographic flights of December 14–15, 1959, and mapped by United States Geological Survey (USGS) from these photos. Named by Advisory Committee on Antarctic Names (US-ACAN) for Edward W. Remington, glaciologist at the South Pole Station during the IGY in 1957.

Johnson Spur
Johnson Spur () is a rocky spur located south-southeast of Taylor Spur, southwest of Batil Spur and north-northwest of Long Peak, on the east side of the Sentinel Range in the Ellsworth Mountains of Antarctica. It forms the southeastern extremity of the Doyran Heights, and overlooks Rutford Ice Stream to the east and Obelya Glacier to the west. The feature was first mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1957–59, and was named by the Advisory Committee on Antarctic Names for William F. Johnson, a meteorologist at South Pole Station South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west.

Mount Benson (Antarctica)
Mount Benson () is a mountain (2,270 m) standing at the northeast side of Thomas Glacier and west of Obelya Glacier, 4.6 mi east of Mount Osborne, in Doyran Heights, southeastern Sentinel Range in Ellsworth Mountains, Antarctica. It was mapped by the USGS from surveys and USN air photos, 1957–59. It was named by the US-ACAN for Robert F. Benson, seismologist at the IGY South Pole Station in 1957.

Sofia
Sofia ( ; bg, София, Sofiya, ) is the capital and largest city of Bulgaria. It is situated in the Sofia Valley at the foot of the Vitosha mountain in the western parts of the country. The city is built west of the Iskar river, and has many mineral springs, such as the Sofia Central Mineral Baths. It has a humid continental climate. Being in the centre of the Balkans, it is midway between the Black Sea and the Adriatic Sea, and closest to the Aegean Sea. Known as Serdica in Antiquity and Sredets in the Middle Ages, Sofia has been an area of human habitation since at least 7000 BC. The recorded history of the city begins with the attestation of the conquest of Serdica by the Roman Republic in 29 BC from the Celtic tribe Serdi. During the decline of the Roman Empire, the city was raided by Huns, Visigoths, Avars and Slavs. In 809, Serdica was incorporated into the Bulgarian Empire by Khan Krum and became known as Sredets. In 1018, the Byzantines ended Bulgarian rule ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Glaciers In The Antarctic
There are many glaciers in the Antarctic. This set of lists does not include ice sheets, ice caps or ice fields, such as the Antarctic ice sheet, but includes glacial features that are defined by their flow, rather than general bodies of ice. The lists include outlet glaciers, valley glaciers, cirque glaciers, tidewater glaciers and ice streams. Ice streams are a type of glacier and many of them have "glacier" in their name, e.g. Pine Island Glacier. Ice shelves are listed separately in the List of Antarctic ice shelves. For the purposes of these lists, the Antarctic is defined as any latitude further south than 60° (the continental limit according to the Antarctic Treaty System).
