The Pacific Ocean is derived from the Latin name Mare Pacificum, "peaceful sea.”

The deepest point is the Mariana Trench some 35,840 feet below sea level

It is the largest body of water on Earth– at an area of 165.2

million Km squared.

This ocean covers about 32% of the Earth's surface and is larger than all of the Earth's land area combined

The ocean's name, derived from Greek mythology, means the “Sea

of Atlas."

It is the saltiest of the world's major oceans; the salinity of the surface waters in the open ocean ranges from 33 to 37

parts per thousand (3.3 - 3.7%)

Endangered marine species include the

manatee, and sea lions.

The Atlantic Ocean is the second-largest ocean, covering about 1/5 of

the Earth's surface.

The Indian Ocean is the third largest body of water in the world, covering

about 20% of the Earth's water surface.

The climate north of the equator is affected by a monsoon wind system causing rainy

seasons that last for months at a time.

The Indian Ocean was the sight of the underwater earthquake that caused the

devastating Asian Tsunami of 2004.

It is the world’s fourth largest ocean and the latest to be defined.

It encircles Antarctica, and its northernmost boundary is defined as the 60° S latitiude.

May be the site of large oil and gas fields near the ocean and continental margin.

It was voted and accepted as a new ocean by the International Hydrographic Organization (IHO) in 2000,

though it has been called the Southern Ocean by mariners for years.

It is the smallest of the world's five oceans and the shallowest.

Its salinity is the lowest on average of the five major oceans, due to low evaporation, as well

as limited outflow to surrounding waters

Endangered marine species include walruses. The area has a fragile ecosystem which is slow to change and slow to recover from

disruptions or damage

The Arctic Ocean occupies a roughly circular basin and covers an area of about 14,056,000 square km. slightly less than

1.5 times the size of the U.S.
