Top 4 Fact About Ocean.

1.where is another ocean of the world found?

The National Geographic Society has mapped the world's oceans. The organization announced that it would recognize the South Ocean, a body of water surrounding Antarctica, as the fifth ocean globally.

 

  Since National Geographic began mapping in 1915, it has recognized four oceans: the Atlantic, Pacific, Indian, and Arctic Oceans. On World Ocean Day, June 8, 2021, it recognized the Southern Ocean as the world's fifth ocean.

  According to National Geographic Society geographer Alex Tait, "The Southern Ocean has long been recognized by scientists, but there was never an international agreement, so we didn't recognize it officially."

 

  In general, National Geographic follows the International Hydrographic Organization on nautical names. IHO works with the United Nations Group of Experts on Geographic Names to standardize names internationally.

  The IHO recognized the Southern Ocean in its 1937 guidelines, but the designation was revoked in 1953 due to controversy. Since then, it has discussed the matter but had not yet received full consent from its members to restore the Southern Ocean.

 

  The Board on Geographic Names has used this name since 1999. And in February this year, NOAA officially recognized the Southern Ocean as a separate ocean. However, the U.S.

  The change, says Alex Tait, aligns with the Society's initiative to conserve the world's oceans, focusing public awareness on one area, particularly one in need of a conservation spotlight. He further said, "this change was the last step, and we want to recognize it as a cause of ecological isolation."

 

  2. Let us now know about the boundaries of the Southern Ocean

  National Geographic now recognizes five world oceans. Except for the Drake Passage and the Scotia Sea, most of the water surrounding Antarctica up to 60 degrees south latitude forms the newly accepted Southern Ocean.

 

  3. By whom is the South Ocean defined?

  While other oceans are defined by the continents surrounding them, the Southern Ocean is defined by a current.

  Scientists estimate that the Antarctic Circumpolar Current was established about 34 million years ago when Antarctica separated from South America. This allowed the uninterrupted flow of water around the earth's surface.

 

  IN A WIDE FLUCTUATING BAND, the ACC flows around Antarctica from west to east, centered around a latitude of about 60 degrees south. This is the line that is now defined as the northern boundary of the Southern Ocean. Inside the ACC, the water is cooler and slightly less saline than the seawater in the north.

 

  Extending from the surface to the ocean floor, the ACC transports more water than any ocean current. It draws water from the Atlantic, Pacific, and Indian Oceans, helping to drive a global circulation system known as a conveyor belt, which transports heat around the planet.

  The cold, dense water that sinks into the ocean floor off Antarctica also helps to store carbon in the deep ocean. In both of those ways, the Southern Ocean has a significant impact on Earth's climate.

  Scientists are currently studying how human-driven climate change is changing the Southern Ocean.

 

  4. What is the climate of the Southern Ocean like?

  As National Geographic Explorer notes in Residence Enrique Sala, the Southern Ocean contains "unique and delicate marine ecosystems that are home to amazing marine life such as whales, penguins, and seals."

 

  The ecological impact of the Southern Ocean is elsewhere. Some seabirds also migrate in and out. By drawing attention to the Southern Ocean, the National Geographic Society hopes to promote its conservation.

  The impact of industrial fishing on species such as krill and Patagonian toothfish has been a concern in the Southern Ocean for decades.

 

  The largest marine protected area in the world was established in the Ross Sea in West Antarctica in 2016. In 1982, a catch limit was imposed in this area. Several organizations are setting aside more MPA to protect the most important feeding grounds of the Southern Ocean, for example, off the Antarctic Peninsula.
