If you sailed between Australia and Antarctica, south of 60° S latitude, which ocean would you be on?

this is the only place I've ever come across the southern ocean.

This ocean has been added to the other 4 since I studied geography in school.

Player #5057873, it's called the Antarctic ocean and it's been added in recent years. I've also never heard 'southern ocean'. What's next, are they gonna call the Arctic ocean 'northern ocean'? Anyway the option Antarctic would've been obvious

Seriously , they used the nickname for an ocean ?

I have never heard it called by this name. Learned something new today.
