How many oceans are there?
Functionally speaking, there is really only one ocean, since every demarcated ocean is connected to at least two others. The reality of a single continuous ocean is also evidenced by thermohaline circulation (also called the Global Ocean Conveyor or the Great Ocean Conveyor Belt), which transports seawater through all the named oceans. Thermohaline circulation continually replaces water at depth with water from the surface and slowly replaces surface water elsewhere with water rising from deeper depths.
Why is the Arctic Ocean so small?
The Arctic Ocean, which is far smaller than the others, is less prominent in people’s minds, perhaps because it occurs on the fringes of the map and tends to be covered (well, mostly) by ice. In reality, however, Earth’s ocean count depends upon one’s perspective.
