The Washington-based National Geographic Society will recognize the body of water surrounding Antarctica, called the “Southern Ocean,” as the world’s fifth ocean.

Washington-based science organization National Geographic Society, AntarcticaIt will recognize the body of water that surrounds and is called the “Southern Ocean” as the fifth ocean of the world.

The Washington Post’un newsThe National Geographic Society, a Washington-based science organization, has mapped the world’s oceans for the first time in over 100 years.

The scientific organization considers the body of water surrounding Antarctica, called the Southern Ocean, to be the fifth ocean in the world after the Arctic Ocean (Arctic Ocean or Arctic Ocean), Atlantic (Atlantic) Ocean, Indian Ocean and Pacific (Great) Ocean. announced that it will.

Alex Tait, a geographer at the National Geographic Society, stated that it has been known in the scientific world for a long time that there is a separate ecological region around Antarctica, but there has been no consensus among scientists about the name and boundaries of the water body in question.

Despite this, Tait said the National Geographic Society had labeled the body of water in Antarctica as the Southern Ocean in its previous maps.

On the other hand, drawing attention to the recognition of the body of water as the fifth ocean of the world, Tait said, “However, at this point, we thought it was important to officially recognize[the Southern Ocean]. People turn to us for geographical truth: How many continents, how many countries, how many oceans? we said.” made its assessment.

Tait pointed out that the official recognition of the Southern Ocean is also important in terms of education. Noting that the National Geographic Society provides online geographic education programs and materials to schools and the public, Tait said that labeling the body of water in Antarctica as the Southern Ocean on maps is key.

Enric Sala, a researcher at the National Geographic Society, defined the Southern Ocean as a discrete body of water characterized by a strong eastward flowing circular current that “constantly chases itself around Antarctica.”

In addition, Sala used the phrase “the ring of ocean at the end of the world that connects the Pacific, Atlantic and Indian oceans” for the Southern Ocean.

Pointing out that Antarctica and its surroundings are among the areas most affected by global warming, Sala said that the recognition of the water body as the world’s fifth ocean may raise awareness about climate change.

The US National Oceanic and Atmospheric Administration (NOAA) defines the Southern Ocean as the area from the coastline of the Antarctic continent to 60 degrees south latitude. The National Geographic Society also considers 60 degrees south latitude to be the boundary of the new ocean, excluding Drake Pass and the Scotia Sea.

NOAA recognized the body of water as the world’s fifth ocean in 1999, which the U.S. Geographic Names Board named the Southern Ocean.

In 2000, NOAA made a proposal to the International Hydrographic Organization (IHO), which monitors and maps the world’s seas and oceans, to recognize the Southern Ocean as the fifth ocean, but a consensus could not be reached among the members of the organization.
