Exploration of the Pacific
The history of voyages that mapped the Pacific Ocean and established contact between its islands, peoples, and outside powers.
Polynesian navigation: Indigenous Pacific wayfinding that uses stars, winds, currents, waves, and other environmental signs. Polynesian voyaging connected islands long before European expeditions entered the ocean.
Celestial navigation: Navigation that determines position or direction by observing celestial bodies. Pacific crews used the Sun and stars to estimate position far from land.
Abel Tasman: A Dutch navigator who charted parts of Australia, New Zealand, and Pacific islands in the seventeenth century. His voyages added extensive southern Pacific coastlines to European maps.
European colonization of Oceania: The process by which European powers established control over territories and peoples in Oceania. Exploration often prepared the way for colonial claims and administration.
Ferdinand Magellan: A Portuguese navigator whose Spanish-led expedition crossed the Pacific in 1520–1521 during the first circumnavigation. His expedition gave Europeans a route across the ocean and its name.
Chronometer: A highly accurate timepiece used at sea to determine longitude from the difference between local time and a reference time. Reliable marine chronometers made longitude measurements during Pacific voyages more precise.
Tupaia: A Raiatean navigator and priest who joined James Cook’s first Pacific voyage. His knowledge and interpreting helped the expedition travel and communicate in Polynesia.
Pacific Islands: The thousands of islands spread across the Pacific Ocean, commonly grouped into Melanesia, Micronesia, and Polynesia. These islands were the destinations, homelands, and meeting places of Pacific voyages.
Álvaro de Mendaña de Neira: A Spanish navigator who led Pacific expeditions that reached the Solomon Islands and the Marquesas. His voyages extended Spanish exploration into the southwestern Pacific.
Marine chart: A map designed for navigation at sea, showing coastlines, depths, hazards, and aids to navigation. Explorers recorded coastlines and hazards in charts that enabled later voyages.
