The Mariner Glacier (73°15′S 167°30′E) is a major glacier over 60 nautical miles (110 km; 69 mi) long, descending southeast from the plateau of Victoria Land, Antarctica, between Mountaineer Range and Malta Plateau, and terminating at Lady Newnes Bay, Ross Sea, where it forms the floating Mariner Glacier Tongue.[1]

The lower reaches and entrance to the Mariner Glacier valley were reconnoitered in December 1958 by Captain John Cadwalader, United States 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.[1]

The Mariner Glacier forms in the Victory Mountains between The Pleiades to the east and the Barker Range to the west. It is below the Evans Névé to the northwest and the Webb Névé to the east.[2] To the south of the Lawrence Peaks it is fed from the east by the Seafarer Glacier, which in turn is fed by the Wilhelm Glacier and the Olson Glacier. Flowing southeast, below Mount Heg it is fed from the north by the Potts Glacier.[3]
Gair Glacier enters from the west to the north of Bunker Bluff, and Argonaut Glacier enters from the southwest before Engberg Bluff. The Meander Glacier enters from the south after Engberg Bluff.[4] The Meander Glacier forms below the Hercules Névé, forming on both sides of Hobbie Ridge.[5] Before its mouth between Cape Crossfire and Index Point the Mariner Glacier recies the small Boyer Glacier from the south. At its mouth, past Emerging Island, the glacier forms the Mariner Glacier Tongue, which abuts the Borchgrevink Glacier Tongue flowing into Lady Newnes Bay.[4]

Tributaries from the left (southwest ) include,
Gair Glacier
73°03′S 166°32′E. A tributary glacier, 10 nautical miles (19 km; 12 mi) long, rising close southeast of Mount Supernal in the Mountaineer Range and flowing east-northeast to enter Mariner Glacier just north of Bunker Bluff. Named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE) 1962–63, for Harry Gair, geologist and leader that season of the NZGSAE northern field party.[10]

Meander Glacier
73°16′S 166°55′E. A large meandering tributary to the Mariner Glacier. The glacier emerges in the vicinity of Mount Supernal and Hobbie Ridge and drains generally eastward for 30 nautical miles (56 km; 35 mi) through the Mountaineer Range to join Mariner Glacier just east of Engberg Bluff. The descriptive name was given by the NZGSAE, 1962–63.[12]
Boyer Glacier
73°18′S 167°21′E. Short tributary glacier situated 10 nautical miles (19 km; 12 mi) west of Index Point in the east part of Mountaineer Range. It flows north into lower Mariner Glacier, Victoria Land. Mapped by USGS from surveys and United States Navy air photos, 1960–64. Named by US-ACAN for Jack W. Boyer, United States Navy, radioman at Hallett Station, 1962.[13]
Webb Névé
72°42′S 166°18′E. The névé at the head of Seafarer Glacier in Victoria Land. Named by the Northern Party of NZGSAE, 1966–67, after the appointed Public Relations Officer Dexter Webb, who was killed before taking up the appointment.[14]
Chocolate Nunatak
72°36′S 166°03′E. An isolated nunatak of red-brown color at the east side of the head of Mariner Glacier, 3 nautical miles (5.6 km; 3.5 mi) west-southwest of Mount McCarthy, Barker Range. A descriptive name apparently applied by B.W. Riddolls and G.T. Hancox, geologists with the NZARP Northern Party to upper Mariner Glacier, 1966–67.[15]
Eureka Spurs
72°42′S 166°00′E. Several rock spurs exposed along the east side of the head of Mariner Glacier, 8 nautical miles (15 km; 9.2 mi) southwest of Mount McCarthy, in Victoria Land. So named by the VUWAE field party to Evans Névé, 1971–72, on the occasion of fossil discoveries made in the area.[16]
Lawrence Peaks

It is bounded by Deception Plateau, Astronaut Glacier, Retreat Hills, and by such western tributaries to the Mariner Glacier as Meander Glacier and Gair Glacier. Named by the northern party of NZGSAE, 1966–67, in appreciation of the party's transport into the field by United States Navy C-130 Hercules aircraft, also as an indication to future parties of a possible C-130 landing place.[18]

Index Point
73°21′S 167°55′E. A low, ice-covered point that forms the east extremity of the Mountaineer Range on the coast of Victoria Land. The feature lies at the terminus of Mariner Glacier, 1.5 nautical miles (2.8 km; 1.7 mi) west of Emerging Island. So named in 1966 by the New Zealand Antarctic Place-Names Committee (NZ-APC) because the shape is suggestive of an index finger.[22]
