The name "Zuckerspitzenbucht" was used for the northwestern of two bays shown on this same stretch of coast by Ludwig Kohl-Larsen in 1930. The SGS, 1951-52, surveyed this coast in detail and confirmed the existence of two bays. As the names derived from Mount Sugartop are misleading (the mountain does not dominate the bay) and as none of the existing names for the feature are used locally, the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1957 proposed a new name.

Jason Peninsula
Jason Peninsula (-66.16667°N, -61°W) is a large peninsula on the east coast of Graham Land comprising several mainly snow-covered summits. It rises above Larsen Ice Shelf and extends from the narrow neck of land east of Medea Dome for 42 nautical miles (80 km), terminating in Cape Framnes. This feature was first seen from seaward on December 1, 1893 by Captain C.A. Larsen, who named one of the high peaks Mount Jason after his ship. Larsen was too distant to map the area in detail, but in 1902 the Swedish Antarctic Expedition under Nordenskjold observed the area from Borchgrevink Nunatak and reported the peaks seen by Larsen to be separated from the mainland. The name Jason Island was subsequently used for Larsen's discovery, but in 1955 the Falkland Islands Dependencies Survey (FIDS) determined this feature to be a large peninsula.

This island was named Irizar Island by the Swedish Antarctic Expedition, 1901-04, under Nordenskjold, for Captain Julian Irizar of the Argentine ship Uruguay, who rescued the shipwrecked Swedish Antarctic Expedition in 1903. In 1904 Dr. Jean B. Charcot, apparently unaware of the Swedish naming, gave the name Irizar to an island off the west coast of Antarctic Peninsula. Since it is confusing to have two islands in close proximity identically named, and because Charcot's Irizar Island has appeared more widely on maps and in reports, the Advisory Committee on Antarctic Names (US-ACAN) accepts the decision of the United Kingdom Antarctic Place-Names Committee (UK-APC) that the name given this island by Nordenskjold be altered. The new name commemorates Ole Jonassen, who accompanied Nordenskjold on his two principal sledge journeys in 1902-03. == See also == * List of antarctic and sub-antarctic islands

Jones Ridge
Jones Ridge (-66.6°N, 99.41667°W) is a small rock ridge, marked by a sharp peak at its seaward end, protruding above the lower reaches of Denman Glacier near the point where the glacier meets the coast. Discovered by the Western Base Party of the Australasian Antarctic Expedition under Mawson, 1911-14, who applied the name Cape Jones, believing the feature marked the west end of the prominent rock cliffs at the east side of Denman Glacier. Dr. S.E. Jones served as medical officer at the Western Base and as leader of the party which extended exploration west to Gaussberg. The name Jones Ridge was reassigned on the Advisory Committee on Antarctic Names (US-ACAN) map of 1955, compiled from aerial photographs taken by U.S. Navy Operation Highjump in February 1947, because a substantial portion of the Denman Glacier flowage separates this feature from the rock cliffs to the east.

The name was given by the third Chilean Antarctic Expedition (1949-50) after the son of commander Jose Duarte of the ship Lautaro. == See also == * List of antarctic and sub-antarctic islands

Jorgensen Nunataks
Jorgensen Nunataks (-83.71667°N, 164.2°W) is a two rock nunataks, rising above the ice-covered ridge which descends eastward from Mount Picciotto, Queen Elizabeth Range. Named by Advisory Committee on Antarctic Names (US-ACAN) for Arthur E. Jorgensen, United States Antarctic Research Program (USARP) meteorologist at South Pole Station, winter 1958.

Jorum Glacier
Jorum Glacier (-65.23333°N, -62.05°W) is a glacier flowing east into Exasperation Inlet, just north of Caution Point, on the east coast of Graham Land. Surveyed by Falkland Islands Dependencies Survey (FIDS) in 1947 and 1955. The United Kingdom Antarctic Place-Names Committee (UK-APC) name alludes to the punchbowl shape of the head of the glacier, a "jorum" being a large drinking bowl used for punch.

Mount Josephine
Mount Josephine (-77.55°N, -152.8°W) is a peak marked by prominent rock outcrops, 6 nautical miles (11 km) southeast of Bowman Peak in the Alexandra Mountains of Marie Byrd Land. Discovered by R. Admiral Byrd while on the Byrd Antarctic Expedition Eastern Flight of December 5, 1929, and named by him during the Byrd Antarctic Expedition (1933-35) for Josephine Clay Ford, daughter of Edsel Ford, contributor to both expeditions.

Jossac Bight
Jossac Bight (-54.26667°N, -37.18333°W) is a bight extending for 7 nautical miles (13 km) along the south coast of South Georgia between Holmestrand and Aspasia Point. The name "Jossac Bite" was used by the early sealers for a bight to the southeast of King Haakon Bay, probably the feature now described. The compound name "Holmestrand-Hortenbucht" (presumably derived from the two existing names Holmestrand and Horten, q.v.) was later used by a German expedition under Kohl-Larsen 1928-29. A form of the earlier name has been approved.

Jotunheim Valley
Jotunheim Valley (-77.63333°N, 161.21667°W) is a high, mainly ice-free valley to the east of Mount Wolak and Utgard Peak in the Asgard Range, Victoria Land. Saint Pauls Mountain stands at the head of the valley. The feature was named in 1982 by the New Zealand Antarctic Place-Names Committee (NZ-APC) from a proposal by G.G.C. Claridge, soil scientist with the DSIR, New Zealand. One of several names in the Asgard Range from Norse mythology; Jotunheim being the home of the giants.

Joubert Rock
Joubert Rock (-68.2°N, -67.68333°W) is a rock with a least depth of 6 fathoms 5 ft, lying 5 nautical miles (9 km) southwest of Pod Rocks and 9 nautical miles (17 km) west-southwest of Millerand Island, in Marguerite Bay. Charted by the Hydrographic Survey Unit from RRS John Biscoe in 1966. Named for Arthur B.D. Joubert, third officer of John Biscoe and officer of the watch when the rock was discovered.

Joubin Islands
Joubin Islands (-64.78333°N, -64.45°W) is a group of small islands lying 3 nautical miles (6 km) southwest of Cape Monaco, Anvers Island, at the southwest end of the Palmer Archipelago.

Discovered and named by the French Antarctic Expedition, 1903-05, under Charcot, who considered it to be a peninsula. Because of its small size the term point is considered more appropriate.

Joungane Peaks
Joungane Peaks (-72.06667°N, -0.28333°W) is a line of about four small peaks just north of Storjoen Peak in the Sverdrup Mountains, Queen Maud Land. Plotted from air photos by the German Antarctic Expedition (1938-39). Remapped by Norwegian cartographers from surveys and air photos by Norwegian-British-Swedish Antarctic Expedition (NBSAE) (1949-52) and air photos by the Norwegian expedition (1958-59) and named Joungane.

Journal Peaks
Journal Peaks (-72.68333°N, -64.91667°W) is a two groups of separated peaks and nunataks which trend east-west for about 8 nautical miles (15 km).

Joyce Glacier
Joyce Glacier (-78.01667°N, 163.7°W) is a glacier immediately north of Pewe Peak, draining from the neve northeast of Catacomb Hill and terminating 2 nautical miles (3.7 km) up-valley (west) of the snout of Garwood Glacier, which would have been a tributary to it in times of more intense glaciation. Named by the New Zealand Blue Glacier Party (1956-57) after Ernest Joyce, a member of British Antarctic expeditions of 1901-04, 1907-09 and 1914-17.
