Portuguese navigator and explorer Ferdinand Magellan was the first European to cross the Pacific Ocean and the first person to command an expedition that sailed around the world. Magellan’s voyage has been called the greatest navigational feat in history.
The world’s oceans and seas vary greatly in their average depth, area, and volume. Currently, the Pacific Ocean is the deepest ocean, it covers the most area, and thus it has the greatest volume. The so-called world ocean refers to all of the earth’s major bodies of water combined.
