Jacobsen Bight

'''Jacobsen Bight''' ({{coor dm|54|25|S|36|50|W|}}) is a [[Bight (geography)|bight]] 4 nautical miles (7 km) wide, indenting the south coast of [[South Georgia]] between [[Larvik Cone]] and [[Cape Darnley]]. The name "Sukkertopp bukta" ([[Sugarloaf Bay]]) was used by [[Olaf Holtedahl]] in 1929 for the whole of the coast between Cape Darnley and Sandefjord, which was shown on his map as one [[bay]]. 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. Jacobsen Bight is for [[Fridthjof Jacobsen]] (1874-1933), who worked at the [[Compania Argentina]] de Pesca station at Grytviken, 1904-21, and later became vice president of the company.

Jason Peninsula

'''Jason Peninsula''' ({{coor dm|66|10|S|61|0|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.

Johannesen Point

'''Johannesen Point''' ({{coor dm|54|1|S|38|14|W|}}) is the southwest point of [[Main Island]] in the [[Willis Islands]] off the west end of [[South Georgia]].

Jomfruene

'''Jomfruene''' ({{coor dm|54|4|S|38|3|W|}}) is a group of three small tussock-covered islands and a number of barren rocks, lying 1 nautical mile (1.9 km) west-northwest of [[Cape Paryadin]], [[South Georgia]].

Following more detailed survey by the SGS, 1955-56, it is now known that there are three small islands, not one large one, and the local name has been extended to the group.

Jonassen Island

'''Jonassen Island''' ({{coor dm|63|33|S|56|40|W|}}) is an [[island]] 2.5 nautical miles (4.6 km) long, lying 0.5 nautical miles (0.9 km) north of [[Andersson Island]] in the south entrance to [[Antarctic Sound]], off the northeast tip of [[Antarctic 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.

Jones Ridge

'''Jones Ridge''' ({{coor dm|66|36|S|99|25|E|}}) 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.

Mount Josephine

'''Mount Josephine''' ({{coor dm|77|33|S|152|48|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''' ({{coor dm|54|16|S|37|11|W|}}) is a [[Bight (geography)|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.

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.
