Stat. 6 (see Table II); are good illustrations. Wollebæk’s Stations (see below 
pp. 35, 40), of May 25 and 31, 1900, are equally good. In the case of the 
Russian observations taken early in the seasen, similar traces are found. 
As an example Station 6, on May 4, 1903, in 73° 40° N. Lat., 33° 29’ 
E. Long. (depth 315 metres) may be taken!. The salinity was nearly 
uniform, 35°03—35'05 %00, between 15 metres and 310 metres, near the 
bottom. The temperature was about 1°9°C. and 199" C. between 5 
metres and 150 metres; deeper it was about 1:47 C.2. The vertical 
circulation, communicating directly with the surface, has reached, at least, 
down below 150 metres. This was near the middle of the deep channel, 
west of Amundsen's Stat. 12 (see Fig. 1), running eastwards into the 
deep hollow of the eastern Barents Sea. Stat. 5 (May 4, 1903) was on 
the slope on the south side of this channel, in 73° 32° N. Lat. and 32° 
25" E. Long. (depth 294 metres), and here there has evidently been more 
horizontal movement, for the vertical circulation has not managed to 
make the water homogeneous down below 50 metres (about 2°1° C. and 
35:05 °/oo). Stat. 7 (May 5, 1903) is in the southern part of the great 
central hollow, on its western slope in 71° 30’ N. Lat. and 38° 0' E. Long,, 
and here there has also been rather much horizontal circulation, as the 
vertical circulation has only been able to make the water homogeneous 
(about —1°45° C. and 34°70 %00) down to 40 metres (as to the rapid 
horizontal movement on this slope see below). 
At Stations 8 (70° 45’ N. Lat., 36° 56° E. Long., depth 166 metres) 
and 9 (70° 32° N. Lat., 36° 38’ E. Long., depth 188 metres) which were 
taken at the same time on the flat bank south of this hollow, the verti- 
cal circulation has made the water practically homogeneous between the 
surface and bottom, with a higher temperature and salinity (about 
108” C. and 34°96 °/oo) at the northern Station, which is nearer the 
deeper hollow. Here the vertical uniformity has not been so complete 
as at the southern Station (about 0:59* C. 34:88” 1/00), where there has 
been less horizontal circulation. The salinity was there probably per- 
fectly uniform (34°87 or 34°88 %/00), whilst the temperature was somewhat 
lower (about 0:38" C.) in the upper water-strata than in the lower (about 
0:65 and 0'69° C.), which might seem to indicate, if the observations be

* Between o and 10 metres there was between 34°88 and 35'or 0/00 and 185" C. This 
lowering of temperature and salinity near the surface has evidently been caused by the 
melting of some ice, which was met with at this Station. The ice cannot have been 
very long in this water, for else the surface layers would have got a much lower 
salinity.
