A marine ecoregion is an ecoregion, or ecological region, of the oceans and seas identified and defined based on biogeographic characteristics. Introduction [ edit ]
The following is a list of marine ecoregions, as defined by the WWF and The Nature Conservancy. The WWF/Nature Conservancy scheme groups the individual ecoregions into 12 marine realms, which represent the broad latitudinal divisions of polar, temperate, and tropical seas, with subdivisions based on ocean basins.
Freshwater ecoregions are distinct from terrestrial ecoregions, which identify biotic communities of the land, and marine ecoregions, which are biotic communities of the oceans. [23] A map of Freshwater Ecoregions of the World, released in 2008, has 426 ecoregions covering virtually the entire non-marine surface of the earth. [24]

From shallow waters to the deep sea, the open ocean to rivers and lakes, numerous terrestrial and marine species depend on the surface ecosystem and the organisms found there. [ 1 ] The ocean's surface acts like a skin between the atmosphere above and the water below, and hosts an ecosystem unique to this environment.
The World Wildlife Fund (WWF) identifies terrestrial, marine, freshwater, and ecoregions: . Global 200; List of terrestrial ecoregions (WWF) 867 terrestrial ecoregions. List of marine ecoregions (WWF), 232 marine ecoregions of the coastal and continental shelf areas.
The marine west coast is located in the path of westerly winds from the ocean that contribute to its cloudy skies, significant amount of precipitation, and mild temperatures. [6] The rainfall, seasons, and temperature are all dependent on each other and are all affected by the global circulatory pattern.
