Map of the Pacific Ocean

The Pacific Ocean is the largest of Earth’s five oceans, covering an area of approximately 165,250,000 km² — about 44% of the world’s total ocean area. Its waters reach an average depth of around 4,280 m, the deepest of the five oceans, and plunge to about 10,925 m at their deepest point, in the Mariana Trench (Challenger Deep). It is bordered by Asia, Oceania, North America, South America and Antarctica.

It contains the deepest known point on Earth, the Challenger Deep, and is ringed by the seismically and volcanically active belt known as the Pacific Ring of Fire. It separates Asia and Oceania from the Americas. By greatest depth it has the deepest maximum depth of the five oceans, while by surface area it ranks 1st. It is the largest ocean of all, accounting on its own for over two-fifths of the world’s ocean surface.

Oceans are the largest bodies of water on the planet and together cover the majority of its surface. Under the five-ocean model used on this site, the global ocean is divided into the Pacific, Atlantic, Indian, Southern and Arctic oceans. The figures above are widely cited approximate values (CIA World Factbook / NOAA); exact measurements vary with how each basin’s boundaries are drawn.
