There are three theories of why the oceans appear blue:
  • The ocean reflects the sky which is blue.
  • Plant and animal life and particles in the water help reflect the color blue.
  • The observer’s eye absorbs only a minimal amount of scattered blue wavelengths, and this is what is reflected back to the eye.

An example of an ocean is the Atlantic.
