National Geographic Recognises Southern Ocean As Fifth Ocean

National Geographic has announced that the Southern Ocean will be considered as the firth ocean of the world along with four oceans–Atlantic, Pacific, Indian, and the Arctic.

The new ocean has been identified by the National Geography Society which has been making maps since 1915.

The National Geographic’s official website said, “The Southern Ocean has long been recognized by scientists, but because there was never agreement internationally, we never officially recognized it.”

“Our maps are updated. The Southern Ocean is treated the same as the traditional four, and the next quiz question about the number of oceans has an updated official answer from National Geographic—five!” it said.

The northern limit of the Southern Ocean varies between about 50 and 62 degrees south latitude. We’re using 60 south latitude as a proxy for the Southern Ocean’s northern ecological limit, this is used by NOAA in the US and by a plurality of members of the IHO

“Most scientists and IHO members use the name the Southern Ocean, some use Antarctic Ocean, and some use Austral Ocean. The ecological boundary of the Southern Ocean follows a sinuous line around the Antarctic continent called the Antarctic Convergence or polar front,” the National Geography said.

Notably, while other oceans are identified by the region they surround, the Southern Ocean is defined by its current, the National Geography said in a report.

According to the National Oceanic and Atmospheric Administration (NOAA), the Southern Ocean covers 30 percent of the Earth’s ocean surface. It is made up of the waters encircling Antarctica.
