September 1—5, 1912, than during September 6—9, 1910, and still lower 

 than during September 6 — 9, 1909. The isotherms of 6*^C. was in the latter 

 year about two degrees farther north (in 76° N., 14*' E) than in September 

 191 2 (in 74*^N., 14OE.). and about one degree farther north than in Sep- 

 tember 1910 (in 75 °N., 14OE.). The isotherm of S^C. showed similar 

 differences. 



The Temperature of the Atlantic Current. Our observations 

 in the Atlantic Current are not sufficiently numerous to enable us to say 



much about its average temperature in 

 1912 west of Spitsbergen; but the com- 

 parisons given above seem to show that 

 the current west and south-west of Spits-

bergen was on the whole colder in 1912 than in 1910, as we also have 

 seen that its salinities were lower. 



At our Stat. 17 the mean value of the temperatures at 100, 200, 300, and 

 400 metres would be about 2 06° C. (see the curve Fig. 18), at the Isachsen 

 Stat. 17 3.13OC., and at the Isachsen Stat. 37 2.79OC. Our Stat. 17 was 

 situated very nearly midway between the two Isachsen stations, and was 

 taken 13 days later in the season than the one, and 20 days earlier than 

 the other. If, therefore, we consider its mean temperature to be compar- 

 able to the mean value (2.96^0 of the temperatures of the two Isachsen 

 stations combined, we find that the water of the Atlantic Current, between
