subantarctic influence is confirmed by the 
geographical distribution of temperatures at 
Stations 285 and 297 (Fig. 17), and salinities 
at 270, 301, and 308 (Fig. 18). 
Of the remaining stations in Series 4 (Sta- 
tions 292, 310, 279, 244, 304, and 239), Sta- 
tion 239 lies in coastal water (Fig, 10), but 
exceptionally contained a rare representation 
of the Southern Subantarctic Group; this 
group was present also at Station 244. Tem- 
peratures indicate that subantarctic water may 
be influencing these two stations (Fig. 17) 
which possibly explains the plankton occur- 
rences. Nevertheless Coastal and Subtropical 
planktonic groups would have been more 
appropriate, especially at Station 239- 
Stations 292, 310, 279, 304, and 244 are 
grouped together in the T-S-P diagram and 
the mixed Coastal, Subtropical, and Subant- 
arctic (mostly Northern) plankton at most of 
them denotes they are sampling in a mixture 
of subantarctic and coastal-subtropical wa- 
ters, Isotherm configuration (Fig. 17) indi- 
cates that, following an initial mixing be- 
tween water of subantarctic origin (as is 
present at Stations 285, 297, and 308) and 
coastal water, the influence of the subantarctic 
water continues shorewards towards Stations 
279, 292 , and, to a lesser degree, 310. Isoha- 
lines (Fig. 18) point to Station 304 being 
influenced by water of subantarctic origin 
as well. 
Series 4 is important for two reasons. First, 
Stations 292, 310, 279, 304, and 244 form a 
compact group in the T-S-P diagram (Fig. 
10). These are geographically isolated sta-
