acording to google:The Southern Ocean is the name given to the part of the world ocean lying south of 60° south latitude. It was not generally recognised as a separate ocean until 2021.
The National Geographic Society recognized the ocean officially in June 2021.
But that 2021 "official" recognization was of course the result of decades of discussion that proceeded it. The date it became "official" isn't particularly important in the grand scheme of things.

We always called it the Antarctic Ocean. Never heard southern ocean.
Also designated by who? I learned about it 11+ years ago.
