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".

The Gilbert and Ellice Islands were formerly designated an ISO 3166-1 alpha-2 country code "GE"
Geology of the Pacific Ocean Geology of the Pacific Ocean The Pacific Ocean evolved in the Mesozoic from the Panthalassic Ocean, which had formed when Rodinia rifted apart around 750 Ma. The first ocean floor which is part of the current Pacific Plate began 160 Ma to the west of the central Pacific and subsequently developed into the largest oceanic plate on Earth. The tectonic plates continue to move today. The slowest spreading ridge is the Gakkel Ridge on the Arctic Ocean floor, which spreads at less than , while the fastest, the East Pacific Rise near Easter Island, has a spreading rate of over
