Mean surface values for a, c, e, g, i zonal velocities and b, d, f, h, j salinity within the Australian–Antarctic Basin for different ocean simulations with the Tasmanian Gateway (TG) at a, b 0 m representing pre-38 Ma, c, d 300 m representing 38 Ma, e, f 450 m representing 34 Ma, g, h 600 m representing ~31 Ma and i, j 1500 m representing post 27 Ma. Black line is the outline of the Early Oligocene Strata (EOS), and light gray lines are bathymetry contours. The orange line marks the position of the vertical profile (Supplementary Fig. 8) at 126°E corresponding to seismic profile GA228-23 (Fig. 2). The continental features are colored in black. The pink star indicates the location of IODP site U1356. BC Budd Coast, SC Sabrina Coast, PB Porpoise Bay, TAS Tasmania.
