Earth comprises 71 per cent of h2o and those acquainted with geography cognize that determination are 4 oceans surrounding the landmass. Four? No, present determination are 5 oceans. The National Geography cartographers person present identified the Southern Ocean arsenic the 5th water connected the planet.

The improvement comes connected the juncture of World Oceans Day which was marked connected June 8. The caller water has been identified by the National Geography Society which has been making maps since 1915 and had truthful acold recognised the Atlantic, Pacific, Indian, and Arctic oceans.

The Southern Ocean has besides been recognised by the US Board connected Geographic Names arsenic the assemblage of h2o extending from the seashore of Antarctica to the enactment of latitude astatine 60 degrees South.

The latitude present marks the bound of the Southern Ocean, wherever the h2o is colder and little salty. The existent pulls h2o from the Atlantic, Pacific, and Indian Oceans helping the planetary circulation of aerial currents.

Antarctica has been facing the brunt of climate alteration and accelerated warming of the planet for decades and scientists are present studying its interaction connected the Southern Ocean, which is location to a delicate marine ecosystem that includes whales, penguins and seals.
