The oceans collectively contain an estimated 97 percent of the world's water and are collectively the planet's largest ecosystem.

Despite historical oceanic quests and modern exploration technologies, only 5 percent of the oceans have been explored.

When considering the scale of the oceans, the amount of knowledge yet to be revealed in the subject of oceanography is equally vast.
