These islands, all located approximately on the Antarctic Convergence ( roughly the northern boundary of the subantarctic region ), are properly considered to be subantarctic islands.
12.
Associated with the Circumpolar Current is the Antarctic Convergence, where the cold Antarctic waters meet the warmer waters of the subantarctic, creating a zone of upwelling nutrients.
13.
Beginning in 1976, Holm-Hansen conducted extensive field research on microbial populations in McMurdo Sound, the Ross Sea, and other ocean areas south of the Antarctic Convergence.
14.
Therefore, despite their being located significantly south of the Antarctic Convergence, they should still be considered to be subantarctic islands by virtue of their location north of the 60?latitude.
15.
The island measures and covers an area of, It is located in the Subantarctic, south of the Antarctic Convergence, which, by some definitions, would place the island in the Southern Ocean.
16.
This region is referred to as the Antarctic Convergence Zone / Antarctic Polar Front because of the sharp gradients in both temperature and salinity ( esp . temperature ) between the Antarctic waters and the Subantarctic waters.
17.
** Antarctic Circumpolar Current ( clockwise around Antarctica, from the Antarctic Divergence to the Subtropical Convergence; spans the Subantarctic Front and Antarctic Convergence ( = Antarctic polar front ), as in graph ).
18.
The " Convention for the Conservation of Antarctic Marine Living Resources " applies to the area south of 60?South latitude as well as the areas further north up to the limit of the Antarctic Convergence.
19.
Once the northward propagating Antarctic Surface Water reaches the Antarctic Convergence zone it begins to sink because it is more dense than the Subantarctic water to its north, but less dense than the Antarctic water to its south.

Among them was Fridthjof Jacobsen whose wife Klara Olette Jacobsen gave birth to two of their children in Grytviken; their daughter Solveig Gunbj�rg Jacobsen was the first child ever born south of the Antarctic Convergence, on 8 October 1913.
