What is the fifth and most recently named ocean?

, Yes, unbelievable because if sea ice melts it doesn't make sea levels rise. Only melted land ice will. Fill a glass with ice and water to the top. As the ice melts, will it overflow? Try it and find out for yourself.

We added a new ocean name but took away a planet. Long live Pluto !

It may have been officially named in 2000, but James Cook referred to it in the 18th century. It’s been the Southern Ocean for hundreds of years.

I do not understand meters spelled like that in this context,to me the measurement is always metres.
