The Amundsen Sea, an arm of the Southern Ocean off Marie Byrd Land in western Antarctica, lies between Cape Flying Fish to the east and Cape Dart on Siple Island to the west. Cape Flying Fish marks the boundary between the Amundsen Sea and the Bellingshausen Sea. West of Cape Dart there is no named marginal sea of the Southern Ocean between the Amundsen and Ross Seas. The Norwegian expedition of 1928–1929 under Captain Nils Larsen named the body of water for the Norwegian polar explorer Roald Amundsen while exploring this area in February 1929.
Marie Byrd Land is the portion of West Antarctica lying east of the Ross Ice Shelf and the Ross Sea and south of the Pacific Ocean, extending eastward approximately to a line between the head of the Ross Ice Shelf and Eights Coast. It stretches between 158°W and 103°24'W. The inclusion of the area between the Rockefeller Plateau and Eights Coast is based upon the leading role of the American Rear Admiral Richard E. Byrd in the exploration of this area. The name was originally applied by Admiral Byrd in 1929, in honor of his wife, to the northwestern part of the area, the part that was explored in that year.
The Dater Glacier is a steep valley glacier in Antarctica, 24 nautical miles long and from 1 to 3 nautical miles wide, flowing northeast in a sinuous course from the eastern slopes of the Vinson Massif between Sullivan Heights and Veregava Ridge to Rutford Ice Stream which borders the eastern flank of the Sentinel Range, Ellsworth Mountains. At the lower end the Dater Glacier coalesces with the terminus of the Ellen Glacier, the two emerging from the Sentinel Range as one stream just north of the Flowers Hills.
The Usarp Mountains is a major Antarctic mountain range, lying westward of the Rennick Glacier and trending N-S for about 190 kilometres (118 mi). The feature is bounded to the north by Pryor Glacier and the Wilson Hills. Its important constituent parts include Welcome Mountain, Mount Van der Hoeven, Mount Weihaupt, Mount Stuart, Mount Lorius, Smith Bench, Mount Roberts, Pomerantz Tableland, Daniels Range, Emlen Peaks, Helliwell Hills and Morozumi Range.
Fowler Ice Rise is a very large Antarctic ice rise between Evans Ice Stream and Carlson Inlet, in the southwest part of the Ronne Ice Shelf. The feature appears to be completely ice-covered except for the Haag Nunataks, which protrude above the surface in the northwestern portion. It was mapped by the United States Geological Survey from Landsat imagery taken 1973–74, and named by the Advisory Committee on Antarctic Names for Captain Alfred N. Fowler, U.S. Navy, Commander of the U.S. Naval Support Force, Antarctica, 1972–74.
Ice Gate Glacier is a narrow hanging glacier, tributary to Astudillo Glacier, between rock spurs on the west slope of Dallmeyer Peak, Danco Coast, Antarctica. It was named by the Polish Antarctic Expedition in about 1992, probably from the gatelike appearance of the spurs at the junction of the two glaciers.
Ives Ice Rise is an ice rise about 1 mile (1.6 km) long at the head of Weber Inlet, an ice-filled inlet situated between Bennett Dome and Berlioz Point on the Beethoven Peninsula, situated in the southwest part of Alexander Island, Antarctica. It was mapped by the United States Geological Survey from U.S. Navy aerial photographs taken 1967–68 and Landsat imagery taken 1972–73. In association with the names of composers grouped in this area, it was named by the Advisory Committee on Antarctic Names after Charles Ives, the American composer.
Jacobsen Head is an ice-covered headland forming the northeastly point of Slichter Foreland, Martin Peninsula, on the Walgreen Coast of Marie Byrd Land, Antarctica. It was first delineated by the United States Geological Survey from air photos taken by U.S. Navy Operation Highjump in January 1947, and was named by the Advisory Committee on Antarctic Names after Commander Glen Jacobsen, U.S. Navy, captain of the icebreaker USS Atka (AGB-3) on the 1954–55 reconnaissance cruise to Antarctica to examine sites for use as science stations during the 1957–58 International Geophysical Year.
Moon Bay is a bay 7 nautical miles (13 km) wide which recedes 4 nautical miles (7 km) between Edinburgh Hill and Renier Point, on the east side of Livingston Island, in the South Shetland Islands off Antarctica. The glaciers Sopot Ice Piedmont, Iskar, Huron, Struma, Kaliakra, Panega and Debelt feed the bay.
The Echelmeyer Ice Stream, formerly known as Ice Stream F, is a glaciological feature of the West Antarctic Ice Sheet. It is an ice stream flowing west to the Shirase Coast to the north of the MacAyeal Ice Stream, and is one of several major ice streams draining from Marie Byrd Land into the Ross Ice Shelf. The ice streams were investigated and mapped by U.S. Antarctic Research Program personnel in a number of field seasons from 1983–84 and originally named Ice Stream A, B, C, etc., according to their position from south to north.
Jutulstraumen Glacier is a large glacier in Queen Maud Land, Antarctica, about 120 nautical miles (220 km) long, draining northward to the Fimbul Ice Shelf between the Kirwan Escarpment, Borg Massif and Ahlmann Ridge on the west and the Sverdrup Mountains on the east. It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (1949–52) and air photos by the Norwegian expedition (1958–59) and named Jutulstraumen. More specifically jutulen are troll-like figures from Norwegian folk tales. The ice stream reaches speeds of around 4 metres per day near the coast where it is heavily crevassed.
MacAyeal Ice Stream, formerly Ice Stream E, is an ice stream in Antarctica flowing west to the juncture of Shirase Coast and Siple Coast between Bindschadler Ice Stream and Echelmeyer Ice Stream. It is one of several major ice streams draining from Marie Byrd Land into the Ross Ice Shelf. The ice streams were investigated and mapped by U.S. Antarctic Research Program personnel in a number of field seasons from 1983–84 onwards and named Ice Stream A, B, C, etc., according to their position from south to north. The name was changed from Ice Scream E by the Advisory Committee on Antarctic Names in 2002 to honor Douglas R. MacAyeal of the Department of Geophysical Sciences, University of Chicago, a U.S. Antarctic Program investigator in the Ross Sea area including study of the Ross Ice Shelf, the West Antarctic Ice Sheet and the Marie Byrd Land ice streams, 1989–2002. Shabtaie Ice Ridge sits between the MacAyeal and Bundschadler ice streams.
