Quick Answer
There are five named oceans: the Pacific, Atlantic, Indian, Southern and Arctic, though they all connect as one global ocean.
The Full Story
The Pacific is the largest and deepest, covering about a third of Earth’s surface and containing the Mariana Trench. The Atlantic is second largest, followed by the Indian Ocean. The Southern Ocean, surrounding Antarctica, was widely recognised more recently; National Geographic officially recognised it in 2021, and it is defined by the Antarctic Circumpolar Current. The Arctic is the smallest and shallowest. Oceans cover about 71 percent of Earth’s surface and hold about 97 percent of its water.
