Southern Ocean Introduction 2014
SOURCE: 2014 CIA WORLD FACTBOOK AND OTHER SOURCES


Background:
A large body of recent oceanographic research has shown that the Antarctic Circumpolar Current (ACC), an ocean current that flows from west to east around Antarctica, plays a crucial role in global ocean circulation. The region where the cold waters of the ACC meet and mingle with the warmer waters of the north defines a distinct border - the Antarctic Convergence - which fluctuates with the seasons, but which encompasses a discrete body of water and a unique ecologic region. The Convergence concentrates nutrients, which promotes marine plant life, and which, in turn, allows for a greater abundance of animal life. In 2000, the International Hydrographic Organization delimited the waters within the Convergence as a fifth world ocean - the Southern Ocean - by combining 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 and which approximates the extent of the Antarctic Convergence. As such, 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). It should be noted that inclusion of the Southern Ocean does not imply recognition of this feature as one of the world's primary oceans by the US Government.

No claims are made regarding the accuracy of Southern Ocean Introduction 2014 information contained here.

2) The rank that you see is the CIA reported rank, which may habe the following issues:
  a) They assign increasing rank number, alphabetically for countries with the same value of the ranked item, whereas we assign them the same rank.
  b) The CIA sometimes assignes counterintuitive ranks. For example, it assigns unemployment rates in increasing order, whereas we rank them in decreasing order
