Joinville Island group

Joinville Island group is a group of antarctic islands, lying off the northeastern tip of the Antarctic Peninsula, from which Joinville Island group is separated by the Antarctic Sound.

Location
The Joinville Island group lies in Graham Land to the east of the tip of Trinity Peninsula, which is itself the tip of the Antarctic Peninsula. It is separated from the mainland by the Antarctic Sound. Joinville Island is at the center of the group. Other islands and rocks include, clockwise from the west, Bransfield Island, D'Urville Island, Wideopen Islands, Brash Island, Danger Islands, Eden Rocks, Paulet Island, Dundee Island.

D'Urville Island
-63.08333°N, -56.33333°W. Northernmost island of the Joinville Island group, 17 nmi long, lying immediately north of Joinville Island, from which it is separated by Larsen Channel. Charted in 1902 by the SwedAE under Otto Nordenskjöld, who named it for Captain Jules Dumont d'Urville, French explorer who discovered land in the Joinville Island group.

Joinville Island
-63.25°N, -55.75°W. Largest island of the Joinville Island group, about 40 nmi long in an east–west direction and 12 nmi wide, lying off the northeast tip of Antarctic Peninsula, from which it is separated by Antarctic Sound. Discovered and roughly charted in 1838 by a French expedition under Captain Jules Dumont d'Urville, who named it for François d'Orléans, Prince of Joinville (1818-1900), the third son of the Due d'Orleans.

Dundee Island
-63.5°N, -55.91667°W. Ice-covered island lying east of the northeast  tip of Antarctic Peninsula and south of Joinville Island. Discovered on January 8, 1893 by Captain Thomas Robertson of the Active and named for the home port, Dundee, Scotland, from whence the ship sailed in company with three other vessels in search of whales.

Antarctic Sound
-63.33333°N, -56.75°W. Body of water about 30 nmi long and from 7 to 12 nmi wide, separating the Joinville Island group from the northeast end of the Antarctic Peninsula. The sound was named by the Swedish Antarctic Expedition (SwedAE) under Otto Nordenskjöld for the expedition ship Antarctic which in 1902, under the command of Captain C.A. Larsen, was the first vessel to navigate it.

Burden Passage
-63.13333°N, -56.53333°W. A marine passage between D'Urville Island and Bransfield Island. Charted in 1947 by the FIDS and named after Eugene Burden (1892-1979), who, as master of the Trepassey, first navigated the passage in January 1947.

Larsen Channel
-63.16667°N, -56.2°W. A strait 1 to 3 nmi wide between D'Urville Island and Joinville Island. Discovered in 1902 by the Swedish Antarctic Expedition under Nordenskjold, and named for Captain C.A. Larsen of the expedition ship Antarctic.

Firth of Tay
-63.36667°N, -55.75°W. A sound, 12 nmi long and 6 nmi wide, extending in a northwest–southeast direction between the northeast side of Dundee Island and the east  portion of Joinville Island. It merges to the northwest with Active Sound with which it completes the separation of Dundee and Joinville Islands. Discovered in 1892–93 by Captain Thomas Robertson of the Dundee whaling expedition and named by him after the Firth of Tay of Scotland.

Active Sound
-63.41667°N, -56.16667°W. A sound, averaging 2 nmi wide, extending in an east-northeast direction from Antarctic Sound and joining the Firth of Tay with which it separates Joinville and Dundee Islands. Discovered in 1892-93 by Captain Thomas Robertson of the Dundee whaling expedition. Robertson named the feature after his ship, the Active, first vessel to navigate the sound.

Smaller islands
Smaller islands, clockwise from the west, include:

Bransfield Island
-63.18333°N, -56.6°W. An island nearly 5 nmi |long, lying 3 nmi southwest of D'Urville Island. The name Point Bransfield, after Edward Bransfield, Master, Royal Navy, was given in 1842 by a British expedition under James Clark Ross to the low western termination of what is now the Joinville Island group. A 1947 survey by the FIDS determined that this western termination is a separate island.

Papua Island
-63.11667°N, -55.95°W. A small circular island lying 4 nmi west of Boreal Point, off the north coast of Joinville Island. The name was applied by the Argentine Antarctic Expedition (1953-54) because large numbers of gentoo penguins (Pygoscelis papua) were sighted on this island.

Wideopen Islands
-63°N, -55.81667°W. A group of islands and rocks lying 7 nmi north of Boreal Point, Joinville Island. Roughly surveyed from a distance by the FIDS in 1953-54. So named by the UK Antarctic Place-Names Committee (UK-APC) in 1958 because of their exposed, isolated position on the south side of Bransfield Strait.

Patella Island
-63.13333°N, -55.48333°W. A small but prominent island, more than 75 m high, lying 2 nmi northwest of Ambush Bay off the north coast of Joinville Island. Surveyed by the Falkland Islands Dependencies Survey (FIDS) in 1953. The name is descriptive of the island's shape; Patella is the Latin name for a limpet.

Etna Island
-63.08333°N, -55.15°W. An island with a high summit, lying 6 nmi north of the eastern end of Joinville Island. Discovered by a British expedition under James Clark Ross, 1839-43, who so named it because of its resemblance to volcanic Mount Etna.

Brash Island
-63.4°N, -54.91667°W. An isolated island lying 5 nmi northwest of Darwin Island, off the southeast end of Joinville Island. Surveyed by the FIDS in 1953. So named by the UK-APC because the island lies in an area where brash ice is frequently found.

Danger Islands
-63.41667°N, -54.66667°W. Group of islands lying 13 nmi east-southeast of Joinville Island. Discovered December 28, 1842 by a British expedition under James Clark Ross, who so named them because, appearing among heavy fragments of ice, they were almost completely concealed until the ship was nearly upon them.

Puget Rock
-63.48333°N, -55.65°W. A rock lying east of Eden Rocks, off the east end of Dundee Island. The name Cape Puget was given by Sir James Clark Ross on December 30, 1842, for Captain William D. Puget, Royal Navy, but it is not clear from Ross' text what feature he was naming. The name Puget Rock was given by the UK Antarctic Place-Names Committee (UK-APC) in 1956 in order to preserve Ross' name in this vicinity.

Eden Rocks
-63.48333°N, -55.66667°W. Two rocks lying just off the east end of Dundee Island. A small island was reported here by Captain James Clark Ross, Royal Navy, on December 30,1842. He named it "Eden Island" for Captain Charles Eden, Royal Navy. Following survey by the Falkland Islands Dependencies Survey (FIDS) in 1953, it was reported that the feature consists of two rocks lying close together. The Eden Rocks are a designated Important Bird Area.

Paulet Island
-63.58333°N, -55.78333°W. A circular island about 1 nmi in diameter, lying 3 nmi southeast of Dundee Island. Discovered by a British expedition under Ross, 1839-43, and named by him for Captain the Right Honorable Lord George Paulet.

Rosamel Island
-63.56667°N, -56.28333°W. A circular island 1 nmi in diameter with precipitous cliffs of volcanic rock rising to a snow-covered peak 435 m high high, lying west of Dundee Island in the south entrance to Antarctic Sound. Discovered by the French expedition, 1837-40, under Captain Jules Dumont d'Urville, and named by him for V. Admiral Claude de Rosamel, French Minister of Marine under whose orders the expedition sailed.
