From Glossary of Meteorology


  1. Same as ocean.

  2. A subdivision of an ocean.

    All seas except "inland seas" are physically interconnected parts of the earth's total saltwater system. Two types are distinguished, mediterranean and adjacent. Mediterraneans are groups of seas, collectively separated from the major water body as an individual sea. Adjacent seas are those connected individually to the larger body.

  3. Sea surface waves within their fetch; opposed to swell.
