Johnsons Glacier
Johnsons Glacier is the 1.8 km long and 2.3 km wide glacier on Hurd Peninsula, Livingston Island in the South Shetland Islands, Antarctica bounded by Charrúa Ridge and Charrúa Gap to the north, Napier Peak to the east, Mirador Hill to the southeast, Hurd Ice Cap (from which it receives ice influx) to the southwest and Mount Reina Sofía to the west. It is draining northwestwards into Johnsons Dock. The glacier provides overland access from the Spanish base Juan Carlos I Base, Juan Carlos Primero to the interior of the eastern Livingston Island. The feature receives its name from the adjacent Johnsons Dock. Location The midpoint of the glacier is located at (Detailed Spanish mapping in 1991, and Bulgarian mapping in 1996, 2005 and 2009).

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] |

Glaciology
Glaciology (; ) is the scientific study of glaciers, or more generally ice and natural phenomena that involve ice. Glaciology is an interdisciplinary Earth science that integrates geophysics, geology, physical geography, geomorphology, climatology, meteorology, hydrology, biology, and ecology. The impact of glaciers on people includes the fields of human geography and anthropology. The discoveries of water ice on the Moon, Mars, Europa and Pluto add an extraterrestrial component to the field, which is referred to as "astroglaciology". Overview A glacier is an extended mass of ice formed from snow falling and accumulating over a long period of time; glaciers move very slowly, either descending from high mountains, as in valley glaciers, or moving outward from centers of accumulation, as in continental glaciers. Areas of study within glaciology include glacial history and the reconstruction of past glaciation. A glaciologist is a person who studies glaciers. A glacial geologist ...

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).

Juan Carlos I Base
Juan Carlos I Antarctic Base, named after the former king of Spain, Juan Carlos I ( es, Base Antártica Española Juan Carlos Primero), is a seasonal (November to March) scientific station operated by Spain, opened in January 1988. Situated on Hurd Peninsula, Livingston Island in the South Shetland Islands, Antarctica. The base is controlled by the Marine Technology Unit of the Spanish National Research Council and is 20 miles away from the Spanish Antarctic base Gabriel de Castilla. The base has undergone several renovations, the closest remodeling was completed in 2018 and it was inaugurated by the Science Minister, Pedro Duque, on February 2, 2019. This latest renovation involved the construction of "new facilities hathave allowed it to double its capacity, up to 51 people, and increase the space available for scientific and technical personnel in laboratories." Location The base is located at which is on the coast of Española Cove, South Bay, in the northern foothill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Reina Sofía
Mount Reina Sofía ( es, Monte Reina Sofía) is the mostly ice-free peak rising to 275 m on Hurd Peninsula, Livingston Island in the South Shetland Islands, Antarctica and surmounting Johnsons Glacier to the east and northeast, and the Spanish Antarctic base Juan Carlos Primero to the north-northwest. The feature is named after Queen Sofía of Spain. Location The peak is located at which is 1.3 km south by west of Ballester Point, 2.24 km southwest of Charrúa Ridge, 2.85 km west of Napier Peak, 2.8 km northwest of Moores Peak Moores Peak is the prominent rocky peak rising to 407 m on Hurd Peninsula, Livingston Island in the South Shetland Islands, Antarctica and surmounting False Bay to the southeast.

Hurd Ice Cap
Hurd Ice Cap is the ice cap covering the central area of southern Hurd Peninsula, Livingston Island in the South Shetland Islands, Antarctica. It extends 4.5 km in northeast-southwest direction and 3.7 km in northwest-southeast direction, and drains both into South Bay to the northwest and into False Bay to the southeast. Its summit point has been nicknamed named ''Dorotea'' by personnel of the nearby Spanish base Juan Carlos Primero and rises to 332 m. The feature receives its name from Hurd Peninsula.

Livingston Island
Livingston Island (Russian name ''Smolensk'', ) is an Antarctic island in the Southern Ocean, part of the South Shetlands Archipelago, a group of Antarctic islands north of the Antarctic Peninsula. It was the first land discovered south of 60° south latitude in 1819, a historic event that marked the end of a centuries-long pursuit of the mythical ''Terra Australis Incognita'' and the beginning of the exploration and utilization of real Antarctica. The name Livingston, although of unknown derivation, has been well established in international usage since the early 1820s. Geography Livingston Island is situated in West Antarctica northwest of Cape Roquemaurel on the Antarctic mainland, south-southeast of Cape Horn in South America, southeast of the Diego Ramírez Islands (the southernmost land of South America), due south of the Falkland Islands, southwest of South Georgia Islands, and from the South Pole.L.

Charrúa Gap
Charrúa Gap (Sedlovina Charrúa \se-dlo-vi-'na cha-'ru-a\) is a flat ice-covered saddle extending in east-west direction between Castillo Nunatak and Charrúa Ridge on Hurd Peninsula, eastern Livingston Island at an elevation of . The gap separates the glacial catchments of Balkan Snowfield and Contell Glacier to the north and Huntress Glacier and Johnsons Glacier. The glacial catchments of the last two glaciers are separated by a nameless ice-covered saddle extending between the midpoint of Charrúa Gap to the north and Napier Peak () to the south. A small nameless lake is ice-dammed in a deep hollow to the east of Charrúa Ridge. The feature takes its name from the adjacent Charrúa Ridge. The Charrúa Gap is part of several overland routes, for example between the Bulgarian base and the Spanish base, from the Bulgarian base to the southern region of Hurd Peninsula and from the Spanish base to Burdick Ridge, Friesland Ridge and Bowles Ridge areas.
