The total ocean area on the earth is about 360 million square kilometers, accounting for 7 1% of the earth's surface area, with an average water depth of about 3795 meters. The ocean contains more than1350 million cubic kilometers of water, accounting for about 97% of the total water of the earth, and only 2% is available for human consumption.

The ocean is one of the main factors that determine the development of the earth's climate. The ocean itself is the largest heat storage body on the earth's surface. Ocean current is the largest heat energy conveyor belt on the earth's surface. The gas exchange between ocean and air has great influence on climate change and development.
