Data gathered by the Soviet OB' and LENA Expeditions during the IGY, in conjunction with data gathered by American, British and other expeditions, are used in the plotting of Atlas Antarktiki. According to it, the current pattern in the Southern Ocean is cyclonic, with centers roughly coinciding with those of the quasistationary climatic cyclones. The so-called Antarctic Convergence is formed in places where the cold Antarctic water meets the warm subantarctic water. Here the cold Antarctic water sinks. Farther to the north, between 35 and 40 degrees S, a subtropical convergence is formed. In addition, there is one divergence zone where the upwelling of bottom water takes place. The cyclonic water movement in the coastal zone of Antarctica creates a zonal distribution of hydrological characteristics: the northern branches bring the cold Antarctic water northward, whereas the southern branches bring the warmer water to the Antarctic coast.
