The Smithsonian Ocean Portal is an educational website created and maintained by the Smithsonian Institution's National Museum of Natural History in Washington, DC. The website features regularly updated, original content from the museum's research, collections, and Sant Ocean Hall as well as content provided by a number of collaborating organizations.
The ocean is a major driver of Earth's water cycle. Ocean water represents the largest body of water within the global water cycle (oceans contain 97% of Earth's water). Evaporation from the ocean moves water into the atmosphere to later rain back down onto land and the ocean. [68]
The Atlantic Ocean is the second-largest of the world's five oceanic divisions, with an area of about 85,133,000 km 2 (32,870,000 sq mi). [5] It covers approximately 17% of Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South ...
e. Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms.
Earth's ocean. The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. 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 the continents of Asia and Australia in the west and the Americas in the east.
The World Ocean Atlas (WOA) is a data product of the Ocean Climate Laboratory of the National Centers for Environmental Information (U.S.). [1] The WOA consists of a climatology of fields of in situ ocean properties for the World Ocean. It was first produced in 1994 [2] (based on the earlier Climatological Atlas of the World Ocean, 1982 [3 ...
Marine life, sea life, or ocean life is the plants, animals, and other organisms that live in the salt water of seas or oceans, or the brackish water of coastal estuaries. At a fundamental level, marine life affects the nature of the planet. Marine organisms, mostly microorganisms, produce oxygen and sequester carbon.
Ocean surfaces occupy 72% of the Earth's total surface. They can be divided into surfaces of the relatively shallow and nutrient rich coastal areas above the continental shelves (light blue), and surfaces of the more expansive and relatively deeper but nutrient poor ocean that lies beyond (deep blue).
