Figure 4. Major water masses, fronts, and current systems of the Southwest Pacific. The ACC reenters the region from the west with DWBC flow commencing east of the Macquarie Ridge complex. Near latitude 50°S, the ACC resumes its eastward path with 20 Sv of DWBC flow continuing northward around the east end of Chatham Rise. SSW = subtropical surface water, STC = subtropical convergence, ASW = Australasian subantarctic water, SAF = subantarctic front, CSW = circumpolar subantarctic water, and AAC = Antarctic convergence.
