This is a natural result of the many glaciers. At 25 m. depth, the tempe- 
rature was 0.5°, falling thereafter to 0° at abt. 100 m., and rising again 
towards the bottom, so that at 150m. we have abt. 1.0°, at 250m. 
abt. 3°, and at 350m. abt. 3,5°, beyond which the increase is only very 
slight (650 m.: 3.77°). 
The salinity likewise increases downwards. In the central portion of 
the fjord, the salinity at 10 m. depth is less (27.2 °/o)) than at the mouth
