Figure F1. Model simulation of sea-surface height at 1/8 degree resolution for the Southwest Pacific Ocean, Tasman Sea, and adjoining Southern Ocean (www7320.nrlssc.navy.mil/global_ncom). To locate Leg 181 sites on this figure, see Figure F2. The Subantarctic (SAF), Subtropical (STF), and Tasman (TF) fronts are well delineated, as indicated in the color key. The southern branch of the west-flowing South Equatorial Current impinges on the Queensland coast a little north of the latitude of New Caledonia, where its main flow is diverted southward in the East Australian Current (EAC) and then eastward again along the Tasman Front. Dynamic eddy activity occurs along all three fronts but is especially prominent along the EAC-TF and its continuation around northern New Zealand as the East Auckland and East Coast currents. The SAF and STF are well separated across the Campbell Plateau region, but east and the west from here lie in such close proximity as to form a single merged zone of intense frontal gradient. The clockwise circulation of cold subantarctic water within the Bounty Trough is well delineated.
