Duchaylard Island ( 65°42′S65°7′W / 65.700°S 65.117°W / -65.700; -65.117 Coordinates: 65°42′S65°7′W / 65.700°S 65.117°W / -65.700; -65.117 ) is an island 3 nautical miles (6 km) long at the west side of Grandidier Channel, lying 1 nautical mile (2 km) southeast of Vieugue Island and 10 nautical miles (18 km) west of Cape Garcia, off the west coast of Graham Land. It was discovered by the French Antarctic Expedition, 1903–05, and named by Jean-Baptiste Charcot for Monsieur du Chaylard, French Minister Plenipotentiary at Montevideo, Uruguay. The recommended spelling follows the form used in Maurice Bongrain's report of 1914 and is now firmly established. [1]

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.

Grandidier Channel

Grandidier Channel is a navigable channel between the west coast of Graham Land, Antarctica, and the north end of the Biscoe Islands, extending from Penola Strait southwestward to the vicinity of Larrouy Island. It was first charted by the French Antarctic Expedition, 1903–05, and named by Jean-Baptiste Charcot for Alfred Grandidier, President of the Paris Geographical Society. Charcot applied the name to the entire body of water between the mainland and the Biscoe Islands but the name has since been restricted to the navigable portion described.

Cape Garcia headland

Cape Garcia is a cape at the north side of the entrance to Barilari Bay, forming the north extremity of Felipe Solo (Obligado) Peninsula on the west coast of Graham Land, Antarctica. The cape was discovered and named "Cap Loqui" by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot. At the same time Charcot named the south entrance point to the bay "Cap Garcia," after Rear Admiral Garcia of the Argentine Navy. The maps of Charcot's French Antarctic Expedition, 1908–10, showed "Cap Garcia" as the north cape of Barilari Bay and the name has since become established for this feature. Charcot did not use the name "Cap Loqui" on the maps of his second expedition but, for the sake of historical continuity, the name Loqui Point has been accepted for the south entrance point.

Emm Rock

Emm Rock is a conspicuous rock 30 metres (100 ft) high, lying 0.5 nautical miles (1 km) off the south coast of King George Island at the east side of the entrance to Potter Cove, in the South Shetland Islands. This rock, presumably known to early sealers in the area, was sketched by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, and charted by Discovery Investigations personnel on the Discovery II in 1935. The name derives from the shape of the rock, which resembles the letter M.

Flank Island is the southernmost of the Myriad Islands, lying 2 nautical miles (4 km) east-northeast of the Snag Rocks in the Wilhelm Archipelago. It was mapped by the Falkland Islands Dependencies Survey from photos taken by Hunting Aerosurveys Ltd in 1956–57 and from the helicopter of HMS Protector in March 1958, and was named by the UK Antarctic Place-Names Committee because of its position.

Gerasimou Glacier is a steep-walled tributary glacier, 5 nautical miles (9 km) long, entering the west side of Shackleton Glacier opposite the Gemini Nunataks, in the Queen Maud Mountains of Antarctica. It was named by the Texas Tech Shackleton Glacier Expedition, 1964–65, for Helen Gerasimou, a polar personnel specialist with the Office of Antarctic Programs, National Science Foundation.

Goldsmith Glacier glacier in Antarctica

Goldsmith Glacier is a glacier flowing west-northwest through the Theron Mountains of Antarctica, 6 nautical miles (11 km) south of Tailend Nunatak. It was first mapped in 1956–57 by the Commonwealth Trans-Antarctic Expedition (CTAE) and named for Rainer Goldsmith, medical officer with the advance party of the CTAE in 1955-56.

Gossler Islands are a group of north–south trending islands 3 nautical miles (6 km) in extent, lying 1.5 nautical miles (3 km) west of Cape Monaco, Anvers Island, in the Palmer Archipelago. They were discovered and named by a German expedition under Eduard Dallmann, 1873–74, in honour of the Gossler banking family of Hamburg. The expedition was funded by the Deutsche Polar-Schifffahrtsgesellschaft shipping company, that was co-owned by Ernst Gossler (1838–1893), a grandson of Senator Johann Heinrich Gossler and a great-grandson of Johann Hinrich Gossler.

The Martin Islands are a group of islands and rocks 5 nautical miles (9 km) in extent lying 5 nautical miles east of the northern part of Renaud Island, and 1 nautical mile (2 km) west of Vieugue Island in Grandidier Channel, Antarctica. A group of islands to the north of "Pitt Island" was roughly charted and named "Martin Islands" for Captain Martin of the Argentine Navy, by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot. Aerial surveys have shown that what appeared to be one large island, Pitt, is actually a group of small islands. As they lie in one group with no logical division between them, the earlier name of Pitt was amended to Pitt Islands and extended to cover all the islands north of Renaud Island. The name Martin Islands was transferred to the group now described in order to preserve Charcot's name in the area.

Mount Maslen is a mountain, 1,200 metres (4,000 ft) high, standing 1 nautical mile (2 km) west of Mount Currie in the Raggatt Mountains of Enderby Land, Antarctica. It was plotted from air photos taken from Australian National Antarctic Research Expeditions aircraft in 1956 and was named by the Antarctic Names Committee of Australia for A.W.G. Maslen, the officer-in-charge at Mawson Station in 1961.

Marie Island

Marie Island is an island 2 nautical miles (4 km) long, which lies immediately north of Cape Evensen on the northwest coast of Stresher Peninsula in Graham Land, Antarctica. The name "Pointe Marie," after the elder sister of Dr. Jean-Baptiste Charcot, was applied by the Third French Antarctic Expedition (1903–05) to a point on the coast close north of Cape Evensen. After the Fourth French Antarctic Expedition (1908–10) Charcot re-applied the name to the southern tip of an island, "Ile Waldeck-Rousseau," in approximately the same latitude. Correlating its survey with those of Charcot, the British Graham Land Expedition (1934–37) identified "Ile Waldeck-Rousseau" as Waldeck-Rousseau Peak on the mainland. The most prominent feature near the peak requiring a name is this island, and the name "Marie Island" preserves Charcot's naming in the locality.

Holtedahl Bay bay

Holtedahl Bay is a bay, 10 nautical miles (19 km) long in a northwest–southeast direction and averaging 6 nautical miles (11 km) wide, between Velingrad Peninsula and Stresher Peninsula along the west coast of Graham Land, Antarctica. The bay is entered southwest of Prospect Point and northeast of Black Head, and has its head fed by Hugi Glacier.

The Horne Nunataks are a group of six nunataks in relative isolation, located on the north side of Goodenough Glacier, about 7 nautical miles (13 km) inland from the west coast of Palmer Land, Antarctica. They were named by the UK Antarctic Place-Names Committee for Ralph R. Horne, a British Antarctic Survey geologist at the Adelaide and Stonington Island stations in 1964–65.

Kannheiser Glacier glacier in Antarctica

Kannheiser Glacier is a glacier about 4 nautical miles (7 km) long, lying 12 nautical miles (22 km) east-southeast of Cape Flying Fish on Thurston Island, Antarctica, and flowing south into the Abbot Ice Shelf. It was first delineated from air photos taken by U.S. Navy Operation Highjump in December 1946, and was named by the Advisory Committee on Antarctic Names for Lieutenant Commander William Kannheiser, U.S. Navy, a helicopter pilot aboard USS Glacier, who explored and photographed new Thurston Island features in February 1960.

Luke Glacier glacier in Antarctica

Luke Glacier is a glacier at least 15 nautical miles (28 km) long, flowing northwest into the head of Leroux Bay on the west coast of Graham Land, Antarctica. It is surmounted by Mount Chevreux on the south, Mount Perchot on the southwest and Mount Radotina on the northeast. The glacier was first sighted and roughly surveyed in 1909 by the Fourth French Antarctic Expedition. It was resurveyed in 1935–36 by the British Graham Land Expedition and later named for George Lawson Johnston, 1st Baron Luke of Pavenham, Chairman of Bovril Ltd, who contributed toward the cost of the expedition.

Rotz Glacier is a tributary glacier 9 nautical miles (17 km) long and 2 nautical miles (3.7 km) wide. It flows west from Wakefield Highland, central Antarctic Peninsula, into Airy Glacier at a point due south of Mount Timosthenes. Photographed by Ronne Antarctic Research Expedition (RARE) on November 27, 1947. Surveyed by Falkland Islands Dependencies Survey (FIDS) in December 1958 and November 1960. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) after Jean Rotz, 16th century French chartmaker and writer on the principles of navigation, who designed an elaborate magnetic compass and became hydrographer to King Henry VIII in 1542.

Lewthwaite Strait

Lewthwaite Strait is a passage 2.5 nautical miles (5 km) wide, lying between Coronation Island and Powell Island in the South Orkney Islands, Antarctica. It was discovered in December 1821, on the occasion of the joint cruise of Captain George Powell, a British sealer in the sloop Dove, and Captain Nathaniel Palmer, an American sealer in the sloop James Monroe. Mr. Lewthwaite was a teacher of navigation in Prince's Street, Rotherhithe, London; Captain Powell left the chart and journal of his Antarctic exploration with Lewthwaite before sailing on his last expedition, on which he met his death.
