There is only one global ocean.
Life itself arose from the oceans.
Even now, when the continents have been mapped and their interiors made accessible by road, river and air, most of the world’s people live no more than 200 miles from the sea and relate closely to it. The oceans had long been subject to the freedom of-the-seas doctrine - a principle put forth in the 17th century, essentially limiting national rights and jurisdiction over the oceans to a narrow belt of sea surrounding a nation’s coastline. The remainder of the seas was proclaimed to be free to all and belonging to none. While this situation prevailed into the twentieth century, by mid-century there was an impetus to extend national claims over offshore resources.
