THE SEA WEST OF SPITSBERGEN. 



31 



Stats. 3 and 4 was re- 

 spectively onl}' about 

 27 and 14 minutes 

 more southerly than 

 Makaroft's Stat. 33, 

 while they were about 200 

 i^ 33' and i^ 46' more 

 northerly than Maka- 

 rotTs Stat. 34. The 

 meridian of Makaroflf's 

 station 33 was be- 

 tween those of Stats. 3 and 4, and that of his Stat. 34 one degree more 

 westerly than Stat. 4 (see Fig. 21). The observations at all four stations 

 were taken in the first week of September of 1899 and 1910. Both Maka- 

 roff's curves show much lower temperatures than those of Stats. 3 and 4, 

 especially in depths of less than 4C0 metres. 



The mean temperature of the water between 50 and ' 450 metres at 

 Makaroff's two stations was 2.76^ C. while the corresponding mean tempera- 

 ture for Stats. 3 and 4 was 3.82*^ C. If these temperatures were compar- 

 able, the Atlantic water should thus have been about loô*^ C. colder in 



1899 than in 1910. 



The vertical tempera- 

 ture-curves of Makaroflf's 

 Stats. 5, 6, and 7 (Fig. 21, 

 Ma 5, Ma 6, and Ma 7) of 

 June 30th and July ist, 

 1899, show much lower 

 temperatures than the curves of Isachsen's 

 Stats. I and 11 of June 25th and 27th, 

 1910 (see Fig. 24), All these observations 

 thus point in the same direction. Hjort's 

 Stat. 64 of September, 1900, was about 

 midway between Makaroflf's Stats. 33 (about 

 55 naut. miles to the north-northwest) and 

 34 (see Fig. 21). The vertical curves of 

 both Makaroflf's stations show higher tem- 

 peratures than the curve of Stat. 64 (see 

 Fig. 22). The following table gives the temperatures in 

 100, 200, 300 and 400 metres at Makaroflf's two stations 

 (Ma 33, Ma 34) and Hjort's station H 64:
