GOO M01 19 05 1908 1910. 1910 Considering the very inaccuratemethods, and the insufficient obser-vation-material at our disposal, a bet-ter agreement cannot be variations seem to have gonein the same direction, as is demon-strated by the curves inl Fig. 35. It might seem probable that thedistribution of the ice in the sea westof Spitsbergen is also more or lessdependent on the variations in theSpitsbergen Atlantic Current. But inthis deep sea it is evidently less de-pendent on the temperature of thewater than in the shallow BarentsSea, and is more dependent on thedistribution of the currents, and onthe prevailing winds. We have previously [1909, pp. 204, et seq.] pointed out that there isprobably a close relation between the annual variations in the temperatureof the Norwegian Atlantic Current and the growth and spawning of thefood-fishes; and we found especially that the Lofoten fisheries had corre-sponding variations. When the Atlantic Current had a comparatively hightemperature in the Sognefjo
