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.

Saturn Glacier is a glacier lying in southeast Alexander Island, Antarctica. The glacier is 15 nautical miles (28 km) long and 6 nautical miles (11 km) wide, flowing southeast into the George VI Ice Shelf of George VI Sound north of Corner Cliffs. Although the glacier is not situated within Planet Heights, its name derives from the nearby mountain range along with many other glaciers named after planets of the Solar System. The nunataks at the head of the glacier are also named after solar system features, for example the Enceladus Nunataks named for a moon of Saturn. The coast in this vicinity was first seen from the air by Lincoln Ellsworth on November 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. The glacier was surveyed in 1949 by the Falkland Islands Dependencies Survey (FIDS) and named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for the planet Saturn, the sixth planet of the Solar System.

Citadel Bastion is a rocky, flat-topped, rocky elevation at the south side of the terminus of Saturn Glacier, facing towards George VI Sound and the Rymill Coast, situated on the east side of Alexander Island, Antarctica. Its maximum elevation is about 645 m. Citadel Bastion lies next to Hodgson Lake. This mountain was mapped from trimetrogon air photography taken by the Ronne Antarctic Research Expedition, 1947–48, and from survey by the Falkland Islands Dependencies Survey, 1948–50. The name applied by the UK Antarctic Place-Names Committee because it resembles a fortified structure with a watchtower at the end of a wall.

Explorers Range

Explorers Range is a large mountain range in the Bowers Mountains of Victoria Land, Antarctica, extending from Mount Bruce in the north to Carryer Glacier and McLin Glacier in the south. Named by the New Zealand Antarctic Place-Names Committee (NZ-APC) for the northern party of New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1963–64, whose members carried out a topographical and geological survey of the area. The names of several party members are assigned to features in and about this range. All of the geographical features listed below lie situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.

Ares Cliff is a cliff in Antarctica. It is formed of pale-colored sandstone and rises to about 500 metres (1,600 ft) east of Mars Glacier and 1 nautical mile (2 km) north of Two Step Cliffs on the east side of Alexander Island. It was mapped from trimetrogon air photography taken by the Ronne Antarctic Research Expedition, 1947–48, and from survey by the Falkland Islands Dependencies Survey, 1948–50, and named by the UK Antarctic Place-Names Committee in association with Mars Glacier after the Greek god of war, Ares.

Neptune Glacier is a glacier on the east coast of Alexander Island, Antarctica, 12 nautical miles (22 km) long and 4 nautical miles (7 km) wide, flowing east into George VI Sound and the George VI Ice Shelf to the south of Triton Point. Although Neptune Glacier is not located within the mountain range Planet Heights, the glaciers name derives from the mountain range along with many other nearby glaciers named after planets of the Solar System. There are also other nearby landforms named in association with these glaciers. The glacier was first sighted from the air by Lincoln Ellsworth on November 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. The mouth of the glacier was positioned in 1936 by the British Graham Land Expedition (BGLE). Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for the planet Neptune following a Falkland Islands Dependencies Survey (FIDS) survey in 1949. The head of the glacier was mapped from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the FIDS in 1960.

Cronus Glacier is a glacier 6 nautical miles (11 km) long and 3 nautical miles (6 km) wide flowing northwest into Bowman Inlet between the Calypso Cliffs and Crabeater Point on the east coast of the Antarctic Peninsula. It was photographed by the Ronne Antarctic Research Expedition on December 22, 1947, and roughly surveyed by the Falkland Islands Dependencies Survey in December 1958. It was named by the UK Antarctic Place-Names Committee after Cronus, the god of agriculture in Greek mythology.

Delius Glacier is a glacier, 6 nautical miles (11 km) long and 2 nautical miles (4 km) wide, flowing west from the Elgar Uplands into Nichols Snowfield, in the northern part of Alexander Island, Antarctica. It was first seen from the air and roughly mapped by the British Graham Land Expedition in 1937. It was more accurately mapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D.

It was named by the UK Antarctic Place-Names Committee after Frederick Delius, the British composer.

Mount Gunter is a conspicuous mountain, 1,970 metres (6,460 ft) high, with precipitous black rock cliffs on its west side, rising at the south side of Hariot Glacier, 3 nautical miles (6 km) east of Briggs Peak, on the west side of the Antarctic Peninsula. It was first roughly surveyed by the British Graham Land Expedition in 1936–37, and was photographed by the Ronne Antarctic Research Expedition in November 1947. It was surveyed by the Falkland Islands Dependencies Survey in 1958, and was named by the UK Antarctic Place-Names Committee after Edmund Gunter, an English mathematician whose "line of numbers" (1617) was the first step toward a slide rule; in 1620 he published tables of logarithms, sines and tangents, which revolutionized navigation.

Pluto Glacier is a glacier on the east coast of Alexander Island, Antarctica, 10 nautical miles (18 km) long and 4 nautical miles (7 km) wide, which flows east into George VI Sound to the north of Succession Cliffs. Although Pluto Glacier is not located within nearby Planet Heights, the glacier was named in association with the mountain range along with many other nearby glaciers that are named after planets of the Solar System. The glacier was first photographed from the air on November 23, 1935, by Lincoln Ellsworth and mapped from these photos by W.L.G. Joerg. Roughly surveyed in 1936 by the British Graham Land Expedition (BGLE). Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for Pluto, then considered the ninth planet of the Solar System, following Falkland Islands Dependencies Survey (FIDS) surveys in 1948 and 1949.

Meridian Glacier is a broad glacier, 9 nautical miles (17 km) long, which flows south along the west side of Godfrey Upland and joins Clarke Glacier between Behaim Peak and Elton Hill, in southern Graham Land, Antarctica. Finn Ronne and Carl R. Eklund of the United States Antarctic Service travelled along this glacier in January 1941. It was photographed from the air by the Ronne Antarctic Research Expedition in November 1947, and was surveyed by the Falkland Islands Dependencies Survey in December 1958. The glacier was so named by the UK Antarctic Place-Names Committee because the glacier flows from north to south along the meridian.

Liotard Glacier glacier in Antarctica

Liotard Glacier is a channel glacier in Antarctica. It is about 3 nautical miles (6 km) wide and 6 nautical miles (11 km) long, and flows north-northeast from the continental ice, terminating in a small ice tongue about 4 nautical miles (7 km) west of Hélène Island. The glacier was delineated from air photos taken by U.S. Navy Operation Highjump, 1946–47, and was named by the Advisory Committee on Antarctic Names for Andre-Frank Liotard, the leader of the French Antarctic Expedition, 1949–51, whose group completed the initial survey of the coastal features as far westward as this glacier.

Ménier Island is an island, the largest in a small island group lying in the mouth of Flandres Bay, 4 nautical miles (7 km) northeast of Cape Renard, off the west coast of Graham Land, Antarctica. The island group was discovered by the Third French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot, who gave them the name "Iles Ménier." The name Ménier is now applied to the largest of these islands.

Mercury Glacier is a glacier on the east coast of Alexander Island, Antarctica, 5 nautical miles (9 km) long and 2 nautical miles (4 km) wide, flowing east into George VI Sound between the Waitabit Cliffs and Keystone Cliffs. The glacier was probably first sighted from a distance by Lincoln Ellsworth, who flew near it and photographed segments of this coast on November 23, 1935. It was named by the UK Antarctic Place-Names Committee for the planet Mercury following rough surveys from George VI Sound by the Falkland Islands Dependencies Survey (FIDS) in 1948 and 1949. The glacier was mapped in detail from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the FIDS in 1960. Although Mercury Glacier is not located within the Planet Heights, it is named in association with the heights along with many other nearby glaciers named after planets of the Solar System.

Mars Glacier is a glacier in the southeastern corner of Alexander Island, Antarctica, 6 nautical miles (11 km) long and 2 nautical miles (4 km) wide, flowing south into the George VI Ice Shelf. The glacier lies between Two Step Cliffs and Phobos Ridge. Mars Glacier was first sighted from the air by Lincoln Ellsworth on November 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. It was first surveyed in 1949 by the Falkland Islands Dependencies Survey and named by the UK Antarctic Place-Names Committee for the planet Mars, the fourth planet from the sun in the Solar System.

Hermes Glacier is a glacier 8 nautical miles (15 km) long, flowing west into Weyerhaeuser Glacier in southern Graham Land, Antarctica. It was surveyed in January 1960 by the Falkland Islands Dependencies Survey who discovered the glacier after several fruitless attempts to find a route out of the mountains east of Earnshaw Glacier. It provided an ideal "road" back to known country and was therefore named after Hermes, the god of roads in Greek mythology. This name by the UK Antarctic Place-Names Committee initiated the idea of naming other features in this area after Greek gods.

The Hyperion Nunataks are a group of about 10 nunataks lying south of Saturn Glacier and 8 nautical miles (15 km) west of the Corner Cliffs, in the southeastern part of Alexander Island, Antarctica. The group was first seen and photographed from the air by Lincoln Ellsworth on November 23, 1935, and mapped from these photos by W.L.G. Joerg. It was surveyed in 1949 by the Falkland Islands Dependencies Survey, and so named by the United Kingdom Antarctic Place-Names Committee in association with nearby Saturn Glacier, Hyperion being one of the satellites of the planet Saturn.

Themis Nunatak is a very large, flat-topped nunatak lying 6 nautical miles (11 km) west-southwest of Mount Umbriel in the southern portion of Alexander Island, Antarctica. The nunatak was first mapped from trimetrogon air photography taken by Ronne Antarctic Research Expedition in 1947–48, and from survey by Falkland Islands Dependencies Survey in 1948-50. Named by United Kingdom Antarctic Place-Names Committee in association with nearby Saturn Glacier, Themis being one of the satellites of the planet Saturn, the sixth planet of the Solar System.

Tethys Nunataks is a minor group of about five snow-free nunataks, lying 2 nautical miles (3.7 km) northeast of Stephenson Nunatak in the southeast corner of Alexander Island, Antarctica. Presumably first seen by Ronne and Eklund of the United States Antarctic Service who sledged through George VI Sound in 1940-41. Surveyed in 1949 by the Falkland Islands Dependencies Survey and named by the United Kingdom Antarctic Place-Names Committee for association with nearby Saturn Glacier, Tethys being one of the satellites of the planet Saturn, the sixth planet of the Solar System.

Venus Glacier is a glacier on the east coast of Alexander Island, Antarctica, 10 nautical miles (18 km) long and 6 nautical miles (11 km) wide at its mouth flowing east into George VI Sound lying between Keystone Cliffs and Triton Point. The coast in this vicinity was first seen from the air by Lincoln Ellsworth on November 23, 1935 and roughly mapped from photos obtained on that flight by W.L.G. Joerg. The glacier was first surveyed in 1949 by the Falkland Islands Dependencies Survey and named by the United Kingdom Antarctic Place-Names Committee for the planet Venus, the second planet of the Solar System.

Ristelen Spur is a rock spur about 5 nautical miles (9 km) southeast of the summit of Breplogen Mountain, standing between the flow of Vestreskorve and Austreskorve Glaciers in the Muhlig-Hofmann Mountains of Queen Maud Land, Antarctica. Plotted from surveys and air photos by the Norwegian Antarctic Expedition (1956–60) and named Ristelen. It is also called Krylova Gora in Russia and simply Ristelen in Norway.
