詳細資訊

The ocean affects the global climate and weather, and also plays a critical role in the carbon cycle. Although the origin of the ocean is unknown, it is generally believed that it has existed since the Hadean and is the driving force for the origin of all living creatures.

Sea water covers about 70% of the earth′s surface, with an average depth of about 3680 meters. In contrast, the average height of the global exposed surface is only 860 meters. The deepest part of the ocean, the Mariana Trench, is 11,000 meters deep, which is nearly 2,200 meters more than Mount Everest, which is 8,848 meters.

Humans have laid their footprints all over the world′s land, but only 5% of the ocean has been explored. As a habitat for creatures, there are about 230,000 species currently identified in the ocean, and most of the abyssal sea remains unexplored. It is estimated that there will be more than 2 million marine species.
