Reference excerpt

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.

Main islands

D'Urville Island

63°05′S 56°20′W. Northernmost island of the Joinville Island group, 17 nautical miles (31 km; 20 mi) 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°15′S 55°45′W. Largest island of the Joinville Island group, about 40 nautical miles (74 km; 46 mi) long in an east–west direction and 12 nautical miles (22 km; 14 mi) 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 Duc d'Orleans.

Dundee Island

63°30′S 55°55′W. Ice-covered island lying east of the northeast tip of Antarctic Peninsula and south of Joinville Island. Discovered on 8 January 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.

Straits

Antarctic Sound

63°20′S 56°45′W. Body of water about 30 nautical miles (56 km; 35 mi) long and from 7 to 12 nautical miles (13 to 22 km; 8.1 to 13.8 mi) 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°08′S 56°32′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°10′S 56°12′W. A strait 1 to 3 nautical miles (1.9 to 5.6 km; 1.2 to 3.5 mi) 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°22′S 55°45′W. A sound, 12 nautical miles (22 km; 14 mi) long and 6 nautical miles (11 km; 6.9 mi) 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°25′S 56°10′W. A sound, averaging 2 nautical miles (3.7 km; 2.3 mi) 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°11′S 56°36′W. An island nearly 5 nautical miles (9.3 km; 5.8 mi) |long, lying 3 nautical miles (5.6 km; 3.5 mi) 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°07′S 55°57′W. A small circular island lying 4 nautical miles (7.4 km; 4.6 mi) 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°00′S 55°49′W. A group of islands and rocks lying 7 nautical miles (13 km; 8.1 mi) 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°08′S 55°29′W. A small but prominent island, more than 75 metres (246 ft) high, lying 2 nautical miles (3.7 km; 2.3 mi) 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°05′S 55°09′W. An island with a high summit, lying 6 nautical miles (11 km; 6.9 mi) 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°24′S 54°55′W. An isolated island lying 5 nautical miles (9.3 km; 5.8 mi) 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°25′S 54°40′W. Group of islands lying 13 nautical miles (24 km; 15 mi) east-southeast of Joinville Island. Discovered on 28 December 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.

Worked examples

Example 1 — a first encounter with Joinville Island group

Start with the simplest possible case. Write down what Joinville Island group claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Joinville Island group before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Joinville Island group ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Joinville Island group

In research: Joinville Island group appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Joinville Island group in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Joinville Island group is common in secondary-school and first-year university syllabi. It links to neighbouring topics Islands of Graham Land, Joinville Island group, so understanding it makes those chapters shorter.
In everyday life: Look for Joinville Island group outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
