The "sea" or the "ocean" are words used to describe all the interconnected salt waters of the world including the five great oceans.

"Sea" is used in the name of specific, smaller bodies of seawater. Seas of the world usually make up partly landlocked areas within the much larger five great oceans.

Seas only partially landlocked and/or bounded by submarine ridges on the sea floor are often referred too as marginal seas. Opinions often differ over which seas are considered marginal seas, some are found within mediterranean seas.

Marginal seas of the Arctic Ocean include: Barents Sea, Beaufort Sea, Chukchi Sea, Kara Sea and Laptev Sea.

There are two types of mediterranean seas: concentration basins, dilution basins.

A concentration basin has a higher salinity (salt) level than the open oceans due to evaporation. The upper layer of water is an inflow of fresh oceanic water and the bottom layer of water is out flowing saltier water.
