Nevertheless, for the convenience of oceanographers and for other practical purposes, it is generally recognized that the huge body of salt water on the Earth's surface is divided into three major oceans – the Pacific Ocean, the Atlantic Ocean, and the Indian Ocean. The Pacific Ocean is the largest ocean of the world. In terms of size, next comes the Atlantic Ocean; followed by the Indian Ocean; followed by Southern Ocean and the Arctic Ocean. The world ocean floor map has details of all major oceans on earth. Some oceanographers denote the Oceanic area around Antarctica to be the Southern Ocean. The Southern Ocean was officially recognized by the International Hydrographic Organization in the spring of 2000. The major salt water oceans of the world include:
The Pacific Ocean : It is the largest of the oceans and occupies a total of 165,250,000 square km; about one-third of the surface area of the globe. Extending from the Antarctic in the south to the Arctic in the north and lying between Asia and Australia on the west and North America and South America on the east, the Pacific also encompasses the Bering Sea, the Sea of Okhotsk, the Sea of Japan, the Yellow Sea, the East China Sea, and the South China Sea. In a world map, Pacific Ocean will be the largest single area occupied by an entity in land or sea.
The Atlantic Ocean : Occupying a surface area of 106,460,000 square km, and covering one-fifth of the Earth's surface, the Atlantic is the second largest ocean. The Atlantic separates Europe and Africa to the East from North and South America on the west. The North Atlantic area encompasses the Caribbean Sea, the Gulf of Mexico, the Gulf of St. Lawrence, the Hudson Bay, and the Baffin Bay on the west; and the Baltic Sea, the North Sea, the Mediterranean Sea, and the Black Sea to the East.
