how many oceans are there: How Many Oceans Are there in the World Four or Five

75% of our earth is submerged in water. Four oceans along with seven continents are the basis of life. However, according to National Geographic, the oceans are not four but five. According to this, the Southern Ocean near Antarctica is also a separate ocean in itself and should be found along with the Arctic, Atlantic, Indian and Pacific Oceans. According to National Geographic Society geographer Alex Tait, scientists have been considering the Antarctic Southern Ocean as separate but international consensus has never been reached, while this part of the world is very special.

Where was he hiding till now?

According to National Geographic, this ocean is 60 degrees south of the coast of Antarctica and is separated from other countries not by any continent but because of its current. The area covered under it is twice that of America. The Society generally follows the names of the International Hydrographic Organization, which recognized the Southern Ocean as separate in its 1937 guidelines but excluded it in 1953. Despite this, the US Geographic Names Board has used the name Southern Ocean since 1999. In February, the National Oceanic and Atmospheric Administration accepted it.

surrounded by danger

This step is special in many respects. National Geographic Explorer Enrique Sala has reported that the southern ocean is home to extremely unique and delicate aquatic ecosystems that are home to creatures such as voles, penguins and seals. There are thousands of species that live only here, and are not found anywhere else. Fishing activities in the region have had a great impact. In such a situation, due to the need for protection, it becomes important to recognize it separately. Apart from this, climate change is also having an impact. Last month, the world’s largest iceberg broke away from Antarctica. A huge iceberg had broken off in February as well. (Reuters)

When was it made?

A particular Antarctic circumpolar current transports vast amounts of water and drives worldwide circulation systems that transport heat to Earth. National Geographic has been preparing maps since 1915 and cartographers have decided on the basis of its current. According to the World Wide Fund, this ocean became the most recent ocean. It was formed 30 million years ago when Antarctica and South America separated from each other. Tate says that if people are not told about this ocean separately, then its needs, importance and dangers will not be understood. (Alexandre Milighini/REUTERS)
