The French explored and settled Polynesia, and the British made three voyages with James Cook to the South Pacific and Australia, Hawaii, and the North American Pacific Northwest . In 1768, Pierre - Antoine Véron, a young astronomer accompanying Louis Antoine de Bougainville on his voyage of exploration, established the width of the Pacific with precision for the first time in history . One of the earliest voyages of scientific exploration was organized by Spain in the Malaspina Expedition of 1789--1794 . It sailed vast areas of the Pacific, from Cape Horn to Alaska, Guam and the Philippines, New Zealand, Australia, and the South Pacific . </P> <P> Growing imperialism during the 19th century resulted in the occupation of much of Oceania by other European powers, and later, Japan and the United States .
