ANTARCTIC CONVERGENCE
. Antarctic convergence is a completely enviable curve of the Antarctic, which marks the boundary where the cold water masses from the south facing the north face the Subantarket's relatively warmer water masses. The Convergence Zone is about 30-50 km wide and its seasonal latitude can vary by 150 km. Antarctic convergence was first described by English astronomer and geophysicist Edmond Haley in 1700. The Convergence Line crosses the Atlantic, Indian and Pacific Oceans between the 48 ° and 61 ° S parallel to the north of the West Wind stream. This line is sometimes considered to be the northern boundary of the Southern Ocean. In the Convergence Zone, the coldest and densest Antarctic water is submerged below the warmest water flowing from the north to a depth of about 800 m and continues to flow northward. The water temperature can drop sharply from +8 ° C to +2 ° C. The water convergence zone is a highly productive environment for marine organisms, especially Antarctic krill. In 1980, the Convention for the Conservation of Antarctic Marine Resources was concluded, where the Convergence Line was defined by the following coordinates: 50 ° S, 0 °; 50 ° S, 30 ° E; 45 ° S, 30 ° E; 45 ° S, 80 ° E; 55 ° S, 80 ° E; 55 ° S, 150 ° E; 60 ° S, 150 ° E; 60 ° S, 50 ° W; 50 ° S, 50 ° W; 50 ° S, 0 °.
