In the eastern part of the Kära Sea and in the western part of the Siberian Sea 

 the temperature of the water, as I have already intimated, is dependent on the neigh- 

 bourhood of the mouths of the large rivers. At the depth of more than 5 fathoms 

 the temperature is generally below 0°, except in the proximity of the rivers. At 

 Dickson Harbour the water even at the depth of 5 fathoms has a temperature of + 9°,() 

 during the first part of August, and off the mouth of the Lena somewhat låter in the 

 year its temperature amounted to + 3°,s at 15 fathoms. The influence of the latter river 

 reaches as far as to the New Siberian Lslands. West of one of these, Blishni Island, 

 the temperature at the depth of 4 fathoms was the same as at the surface, + 2°,6. At 

 all the places east of the New Siberian Islands where dredging were carried on during 

 the voyage of the Vega, the temperature at the depth of 3 — 10 fathoms kept at or 

 below 0°. ') 



A good guidance in judging of the conditions of temperature in the northern 

 part of the American Arctic Sea is afforded by the observations made during Belcher's 

 expedition. According to these ^), the average temperature of the water in Northum- 

 berland Sound is: 



at tlie surface. at the bottom.
