@Southern Ocean
Introduction Southern Ocean
Background:
A decision by the International Hydrographic Organization in the
spring of 2000 delimited a fifth world ocean - the Southern Ocean -
from the southern portions of the Atlantic Ocean, Indian Ocean, and
Pacific Ocean. The Southern Ocean extends from the coast of
Antarctica north to 60 degrees south latitude, which coincides with
the Antarctic Treaty Limit. The Southern Ocean is now the fourth
largest of the world's five oceans (after the Pacific Ocean,
Atlantic Ocean, and Indian Ocean, but larger than the Arctic Ocean).
Geography Southern Ocean
Location:
body of water between 60 degrees south latitude and Antarctica
Geographic coordinates:

distinction of being a large circumpolar body of water totally
encircling the continent of Antarctica; this ring of water lies
between 60 degrees south latitude and the coast of Antarctica and
encompasses 360 degrees of longitude
