B. The Temperature of the Water. 



a. The temperature of the ocean around the coasts is not suf- 

 ficiently known, and consequently the mean values cannot be given. 

 I give, therefore, as an example, some actual measurements, as 

 even these may be instructive in several respects. As regards NW. 

 Iceland, N. Iceland and the northernmost part of the coast of E. 

 Iceland I rely on the measurements carried out during the year 

 1904 on board the Danish Deep Sea Exploration ship "Thor" (Niel- 

 sen, 52).
