Gilbert and Ellice Islands French captain Louis Duperrey was the first to map the whole Gilbert Islands archipelago. He commanded "La Coquille" on its circumnavigation of the earth (1822–1825). Funafuti atoll was named Ellice's Island after Edward Ellice, a British politician and merchant, by Captain Arent de Peyster, who sighted the islands in 1819 sailing on the ship "Rebecca". Ellice owned the cargo of the ship. The name Ellice was applied to all nine islands, of what is now Tuvalu, after the work of English hydrographer Alexander George Findlay. The Gilbert and Ellice Islands were formerly designated an ISO 3166-1 alpha-2 country code "GE"
Pacific Ocean most of the islands in the world. There are about 25,000 islands in the Pacific Ocean. The islands entirely within the Pacific Ocean can be divided into three main groups known as Micronesia, Melanesia and Polynesia. Micronesia, which lies north of the equator and west of the International Date Line, includes the Mariana Islands in the northwest, the Caroline Islands in the center, the Marshall Islands to the west and the islands of Kiribati in the southeast. Melanesia, to the southwest, includes New Guinea, the world's second largest island after Greenland and by far the largest of the Pacific islands.
