It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south and is bounded by Asia and Australia in the west and the Americas in the east. At in area (as defined with an Antarctic southern border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about one-third of its total surface area, making it larger than all of Earth's land area combined.

Ocean color oceans in the global carbon cycle. Ocean colour data is a vital resource for a wide variety of operational forecasting and oceanographic research, earth sciences, and related applications, as well as in many of the Societal Benefit Areas identified by the Group on Earth Observations. A few examples of some of the ways that ocean colour data and related data types have been used include. Ocean color The "color" of the ocean is determined by the interactions of incident light with substances or particles present in the water. White light from the sun is made up of a combination of
