Borders of the oceans seas it contains) as follows: Note that these definitions exclude any marginal waterbodies that are separately defined by the IHO (such as the Kara Sea and East Siberian Sea), though these are usually considered to be part of the Arctic Ocean. The CIA defines the limits of the Arctic Ocean differently, as depicted in the map comparing its definition to the IHO's definition. The Atlantic Ocean separates the Americas from Europe and Africa. It may be further subdivided by the equator into northern and southern portions. The 3rd edition, currently in force, of the International Hydrographic Organization's (IHO) "Limits of
Lincoln Sea Ocean waters flow counterclockwise (cyclonically) along the northern shores of Canada, passing through the Lincoln Sea. Atlantic Ocean waters cyclonically flow in from and return to the Eurasian basin along the Greenland Sea continental slope. The waters of these basins converge at the Lincoln Sea, creating unique vertical temperature and salinity profiles here. Measurements detail that both the Pacific and Eurasian Ocean water profiles are clearly offset from one another, an important facet of the hydrography of the Lincoln Sea. The Lincoln Sea has been found to contain water with three distinct properties. The first concerns the water in the
