Methods from chaos theory are applied to the analysis of the circulation in the Southern Ocean,using velocity fields produced by a realistic global ocean model. We plot the intersections ofindividual trajectories encircling Antarctica with a vertical plane in the Drake passage. Thisso-called Poincare´ section shows a drastic difference between regular trajectories in a coreregion of the Antarctic Circumpolar Current (ACC), and chaotic, mixing trajectories in thesurrounding region. It also shows that there is a region with overturning circulation of approximately3.5 Sv in the ACC, with downwelling on the northern side and upwelling on the southernside, which may be related to the Deacon cell.DOI: 10.1034/j.1600-0870.2002.00020.x
