from the southeast. However, the distribution 
of salinities suggests that highly saline water 
has spread throughout the area. 
Only some general features of the plankton 
distribution in relation to that of the water 
properties will be discussed. From the T-S 
diagram (Fig. 3) it is apparent that the sta- 
tions of Series 1 lie predominantly in the 
warmest waters, only a few being slightly in- 
fluenced by the cool water from the south- 
east -^a condition conforming more to that 
indicated by the distribution of salinities (Fig. 
12). However, the T-S-P diagrams (e.g., Figs. 
6, 10) demonstrate that Subantarctic species 
were present, in small numbers, at several of 
the stations. Thus indications are that water 
of subantarctic origin is entering Foveaux 
Strait, some of it probably from the south- 
east, as is suggested by the conformation of 
the isotherms (Fig. 11). 
Station 79, and the geographically close 
Station 100, both possess a strong represen- 
tion of Subantarctic species. In the T-S-P 
diagram (Fig. 10) Station 79 forms one of 
that group of stations at which occurrences of 
all plankton groups are suggestive of a mix- 
ture of all waters. It is likely, therefore, that 
subantarctic water is present, entering prob- 
ably from the west, along with mixed coastal- 
subtropical waters. That the influence of this 
subantarctic water is weak is suggested by 
both the positions of Stations 79 and 100 in 
the T-S diagram (Fig. 3), and the lack of any 
indication of the water about them in the 
relevant geographic charts (Figs. 11, 12). 
Station 138 is in that part of the T-S-P dia- 
gram (Fig. 10) representative of mixing on a 
minor scale, and Subantarctic, Coastal, and 
Subtropical species were collected. The con- 
figurations of the isolines indicate a small-
