Figure 1. A. The bathymetry of the eastern New Zealand region, with the positions of major fronts at the ocean surface (summer temperatures) and the Antarctic Circumpolar (ACC) and Pacific Deep Western Boundary (DWBC) currents indicated. B. Meridional salinity cross section through the Pacific Ocean (data after Levitus, 1976), with location of the Leg 181 sites projected onto the plane of section.
