Ocean - Wikipedia
The terms "the ocean" or "the sea" used without specification refer to the interconnected body of salt water covering the majority of the Earth's surface. It includes the Atlantic, Pacific, Indian, Antarctic/Southern and Arctic Oceans. As a general term, "the ocean" and "the sea" are often interchangeable, although speakers of British English refer to "the sea" in all cases, even when the body of water is one of the oceans.
