Location of Oscar II Coast on Antarctic Peninsula.

Medea Dome ( 66°11′S62°3′W / 66.183°S 62.050°W / -66.183; -62.050 Coordinates: 66°11′S62°3′W / 66.183°S 62.050°W / -66.183; -62.050 ) is a snow dome, 350 metres (1,150 ft) high, marking the eastern end of Philippi Rise on the east coast of Graham Land, Antarctica. It was surveyed by the Falkland Islands Dependencies Survey in 1953, and was named in 1956 by the UK Antarctic Place-Names Committee in association with Jason Peninsula; in Greek mythology Medea helped Jason to obtain the Golden Fleece and later became his wife.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Philippi Rise mountain in Antarctica

Philippi Rise is a low, snow-covered promontory 7 nautical miles (13 km) wide and extending some 10 nautical miles (18 km) southeast from the east coast of Graham Land. The ice surface is highest in the west, where it rises to about 395 m and is broken by Borchgrevink and Gemini Nunataks. The Swedish Antarctic Expedition under Nordenskjold, 1901–04, reported an ice wall or glacial terrace in the vicinity of Borchgrevink Nunatak. Although unable to determine its nature, Nordenskjold named the feature Philippigletscher, after Emil Philippi. It was determined to be a snow-covered promontory by the Falkland Islands Dependencies Survey (FIDS) during their 1947 survey of this coast.

Graham Land geographical object

Graham Land is the portion of the Antarctic Peninsula that lies north of a line joining Cape Jeremy and Cape Agassiz. This description of Graham Land is consistent with the 1964 agreement between the British Antarctic Place-names Committee and the US Advisory Committee on Antarctic Names, in which the name "Antarctic Peninsula" was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69 degrees south.

Prince Charles Mountains mountain range

The Prince Charles Mountains are a major group of mountains in Mac. Robertson Land in Antarctica, including the Athos Range, the Porthos Range, and the Aramis Range. The highest peak is Mount Menzies. Other prominent peaks are Mount Izabelle and Mount Stinear. These mountains together with other scattered peaks form an arc about 260 miles long, extending from the vicinity of Mount Starlight in the north to Goodspeed Nunataks in the south.

Jason Peninsula

Jason Peninsula is a large peninsula on the east coast of Graham Land comprising several mainly snow-covered summits. It rises above the Larsen Ice Shelf and extends from the narrow neck of land east of Medea Dome for 42 nautical miles (78 km), terminating in Cape Framnes. This feature was first seen from seaward on December 1, 1893 by Carl Anton Larsen, who named one of the high peaks "Mount Jason" after his ship, the Jason. Larsen was too distant to map the area in detail, but in 1902 the Swedish Antarctic Expedition under Otto Nordenskiöld observed the area from Borchgrevink Nunatak and reported the peaks seen by Larsen to be separated from the mainland. The name "Jason Island" was subsequently used for Larsen's discovery, but in 1955 the Falkland Islands Dependencies Survey determined this feature to be a large peninsula.

Bennett Dome is a rounded snow-covered peninsula on the south side of Beethoven Peninsula, Alexander Island, Antarctica. rising to about 460 metres (1,500 ft) between Weber Inlet and Boccherini Inlet. It was photographed from the air by the Ronne Antarctic Research Expedition in 1947 and roughly mapped from the photographs by D. Searle of the Falkland Islands Dependencies Survey in 1960. It was mapped definitively by the United States Geological Survey from U.S. Navy aerial photographs taken 1967–68 and from Landsat imagery taken 1972–73, and named by the Advisory Committee on Antarctic Names for Joseph E. Bennett, the head of the Polar Coordination and Information Section, Division of Polar Programs, National Science Foundation, 1976–86. Bennett Dome is one of the eight peninsulas of Alexander Island.

Borchgrevink Nunatak

Borchgrevink Nunatak is a nunatak 1.5 nautical miles (3 km) long which rises to 650 metres (2,130 ft), standing at the south side of the entrance to Richthofen Pass, on the east coast of Graham Land. It was discovered in 1902 by the Swedish Antarctic Expedition under Otto Nordenskiöld, who named it for C.E. Borchgrevink, leader of the British Antarctic Expedition, 1898–1900, to Victoria Land.

Clausen Glacier is a narrow glacier draining northward from the summit of Mount Takahe in Marie Byrd Land. The terminus of the glacier is just west of Knezevich Rock. It was mapped by the United States Geological Survey from surveys and from U.S. Navy aerial photos, 1959–66, and named by the Advisory Committee on Antarctic Names for Henrik B. Clausen of the University of Bern, Switzerland, United States Antarctic Research Program glaciologist at Byrd Station, 1969–70.

Jorum Glacier glacier in Antarctica

Jorum Glacier is a glacier draining the southeast slopes of Forbidden Plateau, and flowing east along the north side of Austa Ridge into Borima Bay southwest of Furen Point, on the east coast of Graham Land, Antarctica. It was surveyed by the Falkland Islands Dependencies Survey in 1947 and 1955. The UK Antarctic Place-Names Committee name alludes to the punchbowl shape of the head of the glacier, a "jorum" being a large drinking bowl used for punch.

Griffith Glacier is a tributary glacier draining westward from Beacon Dome, the California Plateau and the Watson Escarpment in Antarctica to enter Scott Glacier between Mount McKercher and Mount Meeks. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–63, and was named by the Advisory Committee on Antarctic Names for Lieutenant Commander Philip G. Griffith, an aircraft commander on photographic flights during Operation Deep Freeze 1966 and 1967.

Lookout Dome is an ice-covered, dome-shaped mountain, 2,470 metres (8,100 ft) high, in the Miller Range, Antarctica. It was so named by the New Zealand Geological Survey Antarctic Expedition (1961–62) because its heights offer an extensive view of Nimrod Glacier and were used as a survey station.

Linsley Peninsula peninsula of Thurston Island, Antarctica

Linsley Peninsula is a broad, roughly rectangular ice-covered peninsula which protrudes into the south part of Murphy Inlet, northern Thurston Island, Antarctica, dividing the inlet into two arms at the head. The peninsula was first plotted from air photos taken by U.S. Navy Operation Highjump, 1946–47, and was named by the Advisory Committee on Antarctic Names for Lieutenant Commander Richard G.

Hugi Glacier glacier in Antarctica

Hugi Glacier is a glacier flowing northward into the head of Holtedahl Bay southwest of Rasnik Peak, on the west coast of Graham Land, Antarctica. It was charted by the British Graham Land Expedition under John Rymill, 1934–37, and was named by the UK Antarctic Place-Names Committee in 1959 for Franz Joseph Hugi, a Swiss teacher who was called the "father of winter mountaineering," and was author of two pioneer works on glacier phenomena.

Hill, a USGS topographic engineer who was a member of the Marie Byrd Land Survey Party, 1967–68.

McCarroll Peak mountain in Antarctica

McCarroll Peak is a rock peak, 1,105 metres (3,625 ft) high, standing at the south side of Richthofen Pass on the east coast of Graham Land, Antarctica. The peak was probably first seen by the Swedish Antarctic Expedition under Otto Nordenskjöld, 1901–04. The name "Cape McCarroll" for H.G. McCarroll of Detroit, Michigan, was given to the south side of Nordenskjöld's "Richthofen Valley" by Sir Hubert Wilkins on his flight of December 20, 1928. The name has been modified and applied to the peak here described in order to maintain the intended relationship between the McCarroll and Richthofen features.
