Jules Dumont d'Urville in the context of "D'Urville Island"

Polynesia (UK: /ˌpɒlɪˈniːziə/ POL-in-EE-zee-ə, US: /-ˈniːʒə/ -⁠EE-zhə) is a subregion of Oceania, made up of more than 1,000 islands scattered over the central and southern Pacific Ocean. The indigenous people who inhabit the islands of Polynesia are called Polynesians. They have many things in common, including linguistic relations, cultural practices, and traditional beliefs.

The term Polynésie was first used in 1756 by the French writer Charles de Brosses, who originally applied it to all the islands of the Pacific. In 1831, Jules Dumont d'Urville proposed a narrower definition during a lecture at the Société de Géographie of Paris. By tradition, the islands located in the southern Pacific have also often been called the South Sea Islands, and their inhabitants have been called South Sea Islanders. The Hawaiian Islands have often been considered to be part of the South Sea Islands because of their relative proximity to the southern Pacific islands, even though they are in fact located in the North Pacific. Another term in use, which avoids this inconsistency, is "the Polynesian Triangle" (from the shape created by the layout of the islands in the Pacific Ocean). This term makes clear that the grouping includes the Hawaiian Islands, which are located at the northern vertex of the referenced "triangle".

The Adélie penguin (Pygoscelis adeliae) is a species of penguin common along the entire coast of the Antarctic continent, which is the only place where it is found. It is the most widespread penguin species in the Antarctic, and, along with the emperor penguin, is the most southerly distributed of all penguins. It is named after Adélie Land, in turn, named for Adèle Dumont d'Urville, who was married to French explorer Jules Dumont d'Urville, who first discovered this penguin in 1840. Adélie penguins obtain their food by both predation and foraging, with a diet of mainly krill and fish.

The Dumont d'Urville Station (French: Base antarctique Dumont-d'Urville) is a French scientific station in Antarctica on Île des Pétrels, archipelago of Pointe-Géologie in Adélie Land. It is named after explorer Jules Dumont d'Urville, whose expedition landed on Débarquement Rock in the Dumoulin Islands at the northeast end of the archipelago on January 21, 1840. It is operated by the "French Polar Institute Paul-Émile Victor", a joint operation of French public and para-public agencies. It is the administrative centre of Adélie Land.

Adèle Dorothée Dumont d'Urville (French pronunciation: [adɛl dɔʁɔte dymɔ̃ dyʁvil]; née Pépin, also spelled as Adélie , 1798 – 8 May 1842) was the wife of French explorer Jules Dumont d'Urville, after whom Adélie Land, Adele Island, Adélie penguin and Cape Pepin are named. While Adélie Land, Adele Island and Cape Pepin were named by Jules Dumont d'Urville in honor of his wife, the penguin was named after Adélie Land where it was discovered. In 1981, an airmail postage stamp of the French Antarctic Territory featuring Adèle Dumont d'Urville was released.
