The oceans surrounding Antarctica have been officially named the fifth ocean in the world by National Geographic Technology News, Firstpost.

71% of the earth is covered with water, but there are only four oceans. It seemed a bit unfair, so the kind people at National Geographic (Nat Geo) decided to improve it. And now there is another ocean in the world! They made this announcement on World Oceans Day. So you ask which sea received this title of honor. It is none other than the Antarctic Ocean, the ocean surrounding Antarctica.

Natsio said Since we started mapping in 1915, we have recognized four oceans: the Atlantic Ocean, the Pacific Ocean, India, and the Arctic Ocean. After years of debate on this topic, it was finally decided from June 8th to recognize the Southern Ocean as the fifth sea in the world.

“The Antarctic Ocean has long been recognized by scientists, but without international consensus, it was never officially recognized,” said Alexate, a geographer at the National Geographic Society.

The Antarctic Ocean was controversial as it wondered if it had enough unique features to justify its own name, or if it was a colder extension to the Pacific, Atlantic, and Indian Oceans. It was.

In 1999, the National Oceanic and Atmospheric Administration (NOAA) recognized the Antarctic Ocean as the fifth body of water. But in 2000, all members of the International Hydrographic Organization (IHO) disagreed. The IHO ensures that all oceans, oceans, and navigable waters are properly surveyed and graphed.

After convinced that the ocean deserved its own name, Nat Geo decided that most of Antarctica up to 60 ° S (except the Drake Passage and the Scotia Sea) would make up the Antarctic Ocean.

“Anyone who has been there will have a hard time explaining what is so fascinating, but glaciers are bluer, the air is colder, mountains are more intimidating, and landscapes are elsewhere. Everyone agrees that it’s more attractive than that, “said Seth Sikola Body, a marine scientist and national geographic explorer at the National Oceanic and Atmospheric Administration (NOAA).

In an interview with Washington postEnric Sala, a National Geographic resident explorer, describes the fifth ocean as “a separate body of water characterized by a powerful Antarctic Circumpolar Current that flows eastward and constantly chases around Antarctica.” I will.

He called this body “the ring of the sea at the end of the world that connects the Pacific Ocean, the Atlantic Ocean, and the Indian Ocean.”

National Geographic hopes to draw attention to the ocean and promote conservation efforts here by officially acknowledging the ocean.

Another area where this change will affect is education.

“Students learn information about the ocean world through the oceans you are studying. You can’t learn the details and importance of it without including the Southern Ocean,” said Tate.

According to a National Geographic report, the Antarctic Ocean is defined by its currents, while other oceans are defined by nearby continents. This current, called the Antarctic Circumpolar Current (ACC), is also called a conveyor belt because it helps circulate heat around the earth. It also helps store carbon because cold water sinks to the bottom of the sea.

The ACC was created about 34 million years ago when Antarctica separated from South America. It flows from west to east around Antarctica, and the southern sea is said to be colder and less salty than the northern sea.

A little history

The term “sea” was first used as the name of a river that was thought to surround the earth. The ancient Greeks named the river after Titan Oceanus, the son of Uranus (sky) and Gaia (earth). He married Titan Tethys, the goddess of the primordial waters that nourished the Earth. Oceanus was the father of many sons (called river gods) and many daughters, Oceanids.
