Chart of the World Shewing the Tracks of the U.S. Exploring Expedition, 1838–1842

The U.S. Exploring Expedition surveyed the Pacific Ocean, mapping nearly 300 islands, including the Marianas and Fijis. It explored the coast of Australia, determined that Antarctica was a continent, and charted the northwest coast of North America. The voyage helped establish U.S. claims to the Oregon Territory, Antarctica, and Wake Island in the Pacific.
