Sea

A
sea (pronounced
see) is a large expanse of
saline water connected with an
ocean. The term is also used for large, usually saline,
lakes that lack a natural outlet, such as the
Caspian Sea and the
Sea of Galilee. The term is used in a less geographically precise manner as synonymous with ocean, as in
the tropical sea or
down to the sea shore, or even
sea water referring to water of the ocean.
Many seas are marginal seas.

Extraterrestrial seas
Lunar maria are vast basaltic plains on the Moon that were thought to be bodies of water by early astronomers, who referred to them as "seas."
Liquid water is thought to be present under the surface of several moonss, most notably Europa.
Liquid hydrocarbons are thought to be present on the surface of Titan, though it may be more accurate to describe them as "lakes" rather than "seas". The distribution of these liquid regions will hopefully be better known after the arrival of the Cassini probe.
Science
The term "sea" has also been used in quantum physics. Dirac sea is an interpretation of the negative energy states that comprises the vacuum.
