FigureS1_Sep29.jpgJPEG image202KSchematic representation of the main surface (red lines) and subsurface (blue lines) currents near Australia. Acronyms are as follows: ACC for Antarctic Circumpolar Current; EAC for East Australian Current; FC for Flinders Current; LC for Leeuwin Current; NCJ for North Caledonia Jet; NVJ for North Vanuatu Jet; SCJ for South Carolina Jet; TF for the jet associated to the Tasman Front; TL for Tasman Leakage; ZC for Zeehan Current.
FigureS2_Sep29.jpgJPEG image405KPotential temperature-salinity (Ө-S) diagrams for AAIW in 200 km wide selected bands. These bands, as shown in the top right, are centered (a) along the east coast of Australia and normal to the southern Australian coast approximately along (b) 142°E, (c) 130°E, and (d) 116.5°E. The data points in the Ө-S diagrams are color-coded according to their latitude, and the potential density isolines are shown as dotted gray lines.
FigureS3_Sep29.jpgJPEG image366KPotential temperature-salinity (Ө-S) diagrams for data points within 50 dbar of the 1000 dbar parking depth, in the region between the Australian coast and 60°S and between 115°E and 148°E. (left) All data, (middle) data for westward floats, and (right) data for eastward floats. The data points are color-coded according to their latitude, and the potential density isolines are shown as solid gray lines.
FigureS4_Sep29.jpgJPEG image1331KSeasonal variation of the current speed (color-coded, in m s−1) and current velocity vectors for the region with the EAC and the Tasman Leakage. Each season is calculated as a 3 month average centered on the specified month. (top) The sea-surface fields and (bottom) the 1000 dbar fields.
