Series 5. Stations 1 to 6; 3 to 4.1. SI 
Stations of Series 5 and 6 were occupied 
during cruises between Wellington and Dune- 
din in January and March, respectively. Sta- 
tions of Series 5 precede those of Series 1 by 
three days, but their discussion has been de- 
ferred for convenience of comparison with 
those of Series 6. 
The stations of Series 5 are believed to 
sample either from water of subantarctic ori- 
gin, or from a mixture of this and high- 
salinity, but cool, coastal water. The tempera- 
ture and salinity at Station 5 (Figs. 19a, 20a) 
indicate the presence of water of subantarctic 
origin only. At Station 6 this water is pre- 
dominant, but the slightly increased salinity 
points also to coastal water being incorpo- 
rated. Higher salinities again at Stations 1 to 
4, indicate an increased admixture of the 
coastal water. The steady rise in temperature 
northwards along the coast probably reflects 
a latitudinal increase. However, the distribu- 
tions of temperatures and salinities demon- 
strate that the water is essentially homogene- 
ous and predominantly of subantarctic origin. 
Supporting evidence comes from the plank- 
tonic occurrences. 
Either or both Northern and Southern Sub- 
antarctic groups occur at Stations 2 to 6 (none 
of the species captured at Station 1 was among 
those selected). Coastal species were present 
at Stations 4 and 3, but they do not occur 
elsewhere. These distributions indicate the 
influence of subantarctic water at all stations, 
together with that of coastal water at Stations 
3 and 4.
