Fig. 36. Curve I : Temperature-Anomaly of Spitsbergen Atlantic Current 

 (scale I to the left). Curve II : Mean anomaly of the Winter-Temperature 

 (Dec. — May) at the five northern Meteorological Stations of Norway (scale II

 The agreement between these curves is better than might be expected, 

 considering the insufificiency of the observation-material at our disposal. 



The "Waves" of the Equilines of the Sections. 



The equilines demonstrate in Sections I, II, IV, and VI the same kind 

 of undulations or "waves" as we have frequently observed in sections of 

 the Atlantic Current off the Norwegian coast, and which we have discussed 

 at length in our work on the Norwegian Sea [cf. 1909, pp. 87 ei seq.]. 

 These "waves" in the sections may either be due to some kind of periodical 

 or unperiodical vertical movements of the water-strata, or they may indicate 

 some kind of horizontal movements or vortex-movements of the water- 

 masses. 



In the former case one might expect that they had some connection 

 with the tidal wave, producing periodical variations in the Ocean currents, 

 which would again cause periodical displacements of the water-strata.
