Led by Lieutenant Charles Wilkes, the expedition collected valuable scientific, geographical, and botanical information, significantly expanding knowledge of these areas. It also helped establish American presence globally. The data and specimens gathered contributed to scientific institutions and industry, and the expedition marked an important milestone in U.S. exploration history.
