Fi'diii tlic al>ove table it seems to be sufficiently clear that the 

 salinity of the layers of «ater increa.ses all through the months of 

 .January to April inclusive. 



The reason for this is probably that the rainfall in the winter 

 months is less than in the autumn. The fall which takes the form 

 of snowis also at that time of year a factor which may be ignoi'ed. 

 A g-ood deal of influence on the salinity of the water in the winter, 

 is probably to be found in the fact that much fresh water is im- 

 pi'isoned in the ice, which is formed in the smallei' fiords and at the 

 ends of the ijreater ones. 



fJenerally speakini;' it may be aftirmed that the surface temjx^- 

 rature and the surface salinity decreases the further in one goes in 

 the Vest Fiord, and the values are of coui'se least at the ends of 

 the branch fiords. 



This will be made clear if one foUuws tlie results of the ob- 

 servations made, e. g. from Rombaken to X-æra and Røst. \Mth 

 regard to the factors mentioned, it may be said that the continental and 

 the oceanic powers oppose each other, and one would at once expect 

 to find that the oceanic influence would be more strongly felt in 

 ])r(iportion to distance from the ends of the fiords and ince rerm. 



While tlie temperature and salinity of the surface in the deep 

 offTrano (Tran Island) "'A 1899 was 1.5 and 33.58, the corresponding 

 fiyures at Værø wei-e 3.2 and 34.10 on the -ilst of the same month. 

 ,\nd on the 22nd, there was found 35 pro mille water on the surface 

 (if the sea NW of .Røst and a tempei'ature of .5.05. 



The ol)servatioiLs made there are of consi(h'rable interest.

These observations are made with a Mileee-Csaella's deep water 

 thermometer, while I used Professor Petteeson's waterbottle, which 

 although it is an excellent instrument can hardly be depended upon 

 with respect to its isolating properties when the depths are as great 

 as from 7 to 9 hundred meters. 



The observations made on -7':'. 1899 at any rate siiow that

I>y eom])aring the measurements on the Rost Sea (--/s) with 

 those in tlie Tys Fiord (-"/.•;) very interesting results are obtained.
