Marie Island
Marie Island (-66.11667°N, -65.75°W) is an island 2 nautical miles (3.7 km) long, which lies immediately north of Cape Evensen, Graham Land. The name "Pointe Marie," after the elder sister of Dr. Jean B. Charcot, was applied by the French Antarctic Expedition (1903-05) to a point on the coast close north of Cape Evensen. After the French Antarctic Expedition (1908-10) Charcot re-applied the name to the south tip of an island, "Ile Waldeck-Rousseau," in approximately the same latitude. Correlating its survey with those of Charcot, the British Graham Land Expedition (BGLE) (1934-37) identified "Ile Waldeck-Rousseau" as Waldeck-Rousseau Peak on the mainland. The most prominent feature near the peak requiring a name is the island described. The name Marie Island for this feature preserves Charcot's naming in the locality. == See also == * List of antarctic and sub-antarctic islands

Mariholm
Mariholm (-60.75°N, -45.7°W) is the highest and easternmost island in a small group which lies 0.3 nautical miles (0.6 km) south of Moe Island in the South Orkney Islands. Named on a chart based upon a running survey of the South Orkney Islands by Captain Petter Sorlle in 1912-13.

Marikoppa
Marikoppa (-54.31667°N, -36.7°W) is a mountain, 1,840 m, between Larssen Peak and Paulsen Peak in the Allardyce Range of South Georgia. The name, which is known locally, was used in 1950 by H.B. Paulsen. "Koppa" is a descriptive Finnish word meaning "basket with a lid on top." The mountain was surveyed by the SGS, 1951-52.

Marin Bluff
Marin Bluff (-69.41667°N, -68.6°W) is a small rock bluff rising to 425 m, 5 nautical miles (9 km) east-southeast of Cape Jeremy on the west side of Antarctic Peninsula. The feature is one of several in the area named after winds. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1977 after the marin, a warm south or southeast wind of the Gulf of Lion, France.

Marin Glacier
Marin Glacier (-76.06667°N, 162.36667°W) is a glacier just west of Cape Hickey, flowing southeast into Charcot Cove on the coast of Victoria Land. Mapped by United States Geological Survey (USGS) from ground surveys and Navy air photos. Named by Advisory Committee on Antarctic Names (US-ACAN) in 1964 for Bonifacio Marin, engineman at McMurdo Station, 1962.

Marina Point
Marina Point (-65.25°N, -64.26667°W) is a low rocky point which forms the northwest tip of Galindez Island in the Argentine Islands, Wilhelm Archipelago. First surveyed in 1935-36 by the British Graham Land Expedition (BGLE) under Rymill and named by members of the expedition for Princess Marina, later Duchess of Kent, who was married in November 1934, while the ship Penola was enroute to the Argentine Islands.

Mariner Glacier
Mariner Glacier (-73.25°N, 167.5°W) is a major glacier over 60 nautical miles (110 km) long, descending southeast from the plateau of Victoria Land, between Mountaineer Range and Malta Plateau, and terminating at Lady Newnes Bay, Ross Sea, where it forms a floating glacier tongue. Its lower reaches and entrance to its valley were reconnoitered in December 1958 by Captain John Cadwalader, U.S. Navy, and two members of New Zealand Geological Survey Antarctic Expedition (NZGSAE), in a flight from the icebreakers USS Glacier and USS Staten Island which were lying close off the south end of Coulman Island, in an attempt to land expedition members on the mainland. Named by NZGSAE, 1958-59, as a tribute to the work of mariners in Antarctic research and exploration.

Mariner Glacier Tongue
Mariner Glacier Tongue (-73.45°N, 168.33333°W) is the broad seaward extension of the Mariner Glacier in Victoria Land. The feature is just west of and abuts the Borchgrevink Glacier Tongue where it discharges into Lady Newnes Bay. Named in association with Mariner Glacier.

Mariner Hill
Mariner Hill (-71.85°N, -68.33333°W) is a prominent snow-free conical hill, rising to about 500 m, midway between Syrtis Hill and Two Step Cliffs, Alexander Island. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) in 1993 after Mariner 9, the NASA probe which was the first spacecraft to orbit the planet Mars, in 1971.

Mariner Islands
Mariner Islands (-66.01667°N, 101.15°W) is a group of rocky islands and rocks forming the north-central group of the Highjump Archipelago, bounded by Edisto Channel on the west, Gossard Channel on the south, and Remenchus Glacier on the east. Mapped from air photos taken by U.S. Navy Operation Highjump, 1946-47, and named by the Advisory Committee on Antarctic Names (US-ACAN) to commemorate the discovery of a large ice-free region at the west end of the Knox Coast by the crew of the PBM-Martin Mariner seaplane commanded by D.E. Bunger. During photographic reconnaissance of this coastal area in January 1947, the aircraft landed on one of the inlets indenting the Bunger Hills and ground-level photographs and water samples were obtained at that time. == See also == * List of antarctic and sub-antarctic islands

Marinovic Beach
Marinovic Beach (-77.58333°N, 163.56667°W) is a gently sloping beach on the south shore of Explorers Cove, New Harbor, on the Scott Coast of Victoria Land. Named by Advisory Committee on Antarctic Names (US-ACAN) after Baldo Marinovic, graduate student (biology), University of California, Santa Cruz, and member of the 1985 winter party at McMurdo Station. During 1984-85, the sea off this beach was a site for the study of reproductive biology and larval ecology of shallow-water echinoderms by biologists of the University of California, Santa Cruz. The name came into local use following the selection of the beach by Marinovic, correctly, as a likely place to study echinoderms.

Marion Nunataks
Marion Nunataks (-69.75°N, -75.25°W) is a small group of nunataks rising to about 600 m on the north shore of Charcot Island, midway between Mount Monique and Mount Martine. Discovered and roughly mapped on January 11, 1910, by the French Antarctic Expedition under Dr. Jean B. Charcot, and named by him in association with Mount Monique and Mount Martine after his daughter, Marion. Photographed from the air on February 9, 1947, by U.S. Navy Operation Highjump and mapped from these photos by Searle of the Falkland Islands Dependencies Survey (FIDS) in 1960.

Maris Nunatak
Maris Nunatak (-69.98333°N, 73.15°W) is a small coastal nunatak 2 nautical miles (3.7 km) east-northeast of Whisnant Nunatak, situated at the junction of Rogers Glacier and the east side of Amery Ice Shelf. Delineated in 1952 by John H. Roscoe from air photos taken by U.S. Navy Operation Highjump (1946-47), and named by him for R.L. Maris, air crewman on Operation Highjump photographic flights over this and other coastal areas between 14 and 164 east longitude.

Mount Markab
Mount Markab (-70.93333°N, -67.03333°W) is a striking mountain with a pointed peak which provides a notable landmark. Located on the north side of the Pegasus Mountains, about 10 nautical miles (18 km) northeast of Gurney Point, on the west coast of Palmer Land. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) after the star Markab in the constellation of Pegasus.

Marker Rock (-66.08333°N, -65.78333°W) is a rock lying 1.5 nautical miles (2.8 km) north-northwest of Turnabout Island in the Saffery Islands, off the west coast of Graham Land. Charted by the British Graham Land Expedition (BGLE) under Rymill, 1934-37. So named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1959 because it marks the ships' passage through the Saffery Islands.

Markham Bay (Antarctica)
Markham Bay (-64.28333°N, -57.3°W) is a bay 8 nautical miles (15 km) wide, lying between Ekelof Point and Hamilton Point on the east side of James Ross Island. Possibly first seen by a British expedition under Ross, who explored this area in 1842-43. First charted by the Swedish Antarctic Expedition, 1901-04, under Nordenskjold, who named it for Sir Clements Markham.
