The Atlantic Ocean is the world's second largest ocean. It covers a total area of about 106,400,000 square kilometres (41,100,000 square miles). It covers about 20 percent of the Earth's surface. It is named after the ancient god Atlas from Greek mythology. Its name means "Sea of Atlas."[1]


The Atlantic Ocean is bounded on the west by North and South America. It connects to the Arctic Ocean through the Denmark Strait, Greenland Sea, Norwegian Sea and Barents Sea. It connects with the Mediterranean Sea through the Strait of Gibraltar. In the southeast, the Atlantic merges into the Indian Ocean. The 20° East meridian defines its border[2]

In the southwest, the Drake Passage connects it to the Pacific Ocean. The Panama Canal links the Atlantic and Pacific.The Atlantic Ocean is second in size to the Pacific. It occupies an area of about 106,400,000 square kilometres (41,100,000 sq mi).[3] The volume of the Atlantic, along with its adjacent seas (the seas next to it), is 354,700,000 cubic kilometres. The average depth of the Atlantic, along with its adjacent seas, is 3,339 metres (1,826 fathoms; 10,955 ft).
