The Waves of the Equilines of the Sections. The equilines demonstrate in Sections I, II, IV, and VI the same kindof undulations or waves as we have frequently observed in sections ofthe Atlantic Current off the Norwegian coast, and which we have discussedat length in our work on the Norwegian Sea [cf. 1909, pp. 87 el seq.].These waves in the sections may either be due to some kind of periodicalor unperiodical vertical movements of the water-strata, or they may indicatesome kind of horizontal movements or vortex-movements of the water-masses. In the former case one might expect that they had some connectionwith the tidal wave, producing periodical variations in the Ocean currents,which would again c
