362 K. STEPHENSEN. 
The only ringtrawl haul made here (St. 28) cannot be compared 
with the hauls in Bredefjord, as much of the material must have been 
lost; as mentioned above (p. 236) we did not here employ the same method 
of dealing with the content as at the other stations. 
HYDROGRAPHY. 
Investigation of the physical conditions was made by measurement 
of temperature and salinity. Dr. J. Nietsen, Hydrographer to the 
“Tjalfe” expedition, and Dr. J. P. JacoBseNn have here assisted me in 
various ways, for which I beg to proffer my best thanks. I have also 
to thank Prof. Martin KnupseEn for kindly lending me the areometers 
from the “Ingolf’’ expedition. 
The salinity was measured by areometer; the figures for this however, 
make no claim to absolute accuracy, as it was very difficult to take a 
correct reading owing to the vibration of the motor boat. We were 
unfortunately unable to measure the salinity during the second half of 
the expedition, as our water bottle was broken at St. 76, and it was 
found impossible to get it repaired at the machine shops in Ivigtut. 
Both temperature and salinity were noted at all dredgings (up to 
St. 75, of course) we had also intended to measure the salinity and 
temperature at the same places and depths where the Nan- 
sen-net was employed; i.e. at the mouth, in the central por- 
tion, and at the base, of each fjord. In the Kvanefjord, we were 
prevented by ice from going even half way up the fjord, so that no mea- 
surements are available for the inner portion; while as regards Brede- 
fjord, the accident to our water bottle precluded the measuring of salinity 
in the inner portion, and the same applies to Bredefjord Sermilik, to 
Skovfjord, and Tunugdliarfik. 
The results will be seen from the accompanying tables; as already 
mentioned, however, the figures for salinity can hardly be strictly accu- 
rate. For purposes of comparison with the measurements made at the 
same places where the Nansen-net was used, the results of the dredgings 
are arranged for each fjord according to depth. (Unfortunately we had 
only 600 metres of line for the thermometer and water bottle, so that 
it was impossible to measure at greater depth). The comparison of 
these figures will naturally not give any absolutely reliable result, as the 
manner in which the stations were spread over the whole of the fjord 
is here disregarded; the figures should however, serve to give some sort 
of an idea as to the condition from the surface downward. 
1. The Atlantic Fjords. 
Bredefjord and Sermilik. (for depths etc. vide p. 233, 353), The 
surface temperature is here very variable, but is at any rate fairly high; 
salinity likewise variable, but at 10m. depth it is still only abt. 30 °/o9.
