Wilkes set sail on the first American exploring expedition with a team of scientists and artists in August 1838 to survey the remote regions of the South Pacific. Wilkes and his men explored the South Pacific Islands, Hawaii, Australia, New Zealand, California, Singapore, the Cape of Good Hope, and St. Helena. The United States Exploring Expedition "was the first American scientific expedition of any size, charged to 'extend the bounds of Science and promote the acquisition of knowledge,' and was one of the most ambitious Pacific expeditions ever attempted" (Forbes). Wilkes's survey of the Pacific Islands resulted in over 200 new charts for 280 islands, and he was the first to use the term "Antarctic Continent." Ferguson 4209; Forbes 1574; Haskell 2B; Howes W-414.
