Figure 6 shows two pairs of Sea Surface Temperature (SST) images of the study area. In two of them (18 Nov, 1991 and 23 Sep, 1992), the EAC is present as a well defined current that flows across the mooring array and separates from the coast around 32° S. However, in the other pair (31 Aug, 1992 and 23 Feb, 1993) it appears the EAC changes its separation point and is no longer flowing across the array. Instead, colder water from the southern Tasman Sea occupies a cyclonic circulation in the area of the array. As demonstrates, times when the EAC has separated north of the array coincide with weak southward or northward volume transport. Hence, it is expected that the mean volume transport obtained by the PCM3 array is an underestimate of the net southward flow through the region [Mata et al., 2000].
