The borders of the oceans are the limits of Earth's oceanic waters.The definition and number of oceans can vary depending on the adopted criteria. The principal divisions (in descending order of area) of the five oceans are the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern (Antarctic) Ocean, and Arctic Ocean.
World map of the five-ocean model with approximate boundaries. This list of countries which border two or more oceans includes both sovereign states and dependencies, provided the same contiguous territory borders on more than one of the five named oceans, the Pacific, Atlantic, Indian, Southern, and Arctic.

Distinct boundaries between ocean surface waters and deep waters can be drawn based on the properties of the water. These boundaries are called thermoclines (temperature), haloclines (salinity), chemoclines (chemistry), and pycnoclines (density). If a zone undergoes dramatic changes in temperature with depth, it contains a thermocline, a ...
A competing and also scientifically valid boundary between the two oceans was put forward by the researchers Juan Ignacio Ipinza Mayor and Cedomir Marangunic Damianovic, who suggested that separation of the Pacific and Atlantic oceans could be delimited by the Shackleton fracture zone, a natural submarine fault line and mid-ocean ridge, and the ...

The map accompanying the first edition of Limits of Oceans and Seas. Limits of Oceans and Seas (French: Limites des Océans et Mers or Limites des Océans et des Mers, S-23) is a special publication of the International Hydrographic Organization (IHO) defining the names and borders of the oceans and seas.
The North Atlantic deep water (NADW) is a complex of four water masses, two that form by deep convection in the open ocean – classical and upper Labrador sea water – and two that form from the inflow of dense water across the Greenland-Iceland-Scotland sill – Denmark Strait and Iceland-Scotland overflow water.
Orogenic belts occur where two continental plates collide and push upwards to form large mountain ranges. These are also known as collision boundaries. Subduction zones occur where an oceanic plate meets a continental plate and is pushed underneath it. Subduction zones are marked by oceanic trenches.
