Description: The area of the World Ocean is 361 million square kilometers (139 million sq mi), its volume is approximately 1.3 billion cubic kilometers (310 million cu mi), and its average depth is 3,790 meters (12,430 ft).[4] Nearly half of the world's marine waters are over 3,000 meters (9,800 ft) deep. The vast expanses of deep ocean (anything below 200m) cover about 66% of the Earth's surface. This does not include seas not connected to the World Ocean, such as the Caspian Sea.
