Diurnal Variations in Underwater Noise beneath Springtime Sea-ice

Abstract

UNDERWATER ambient noise in ice-covered seas can show a dependence on air temperature. This temperature dependence is particularly striking in spring in the latitudes of the Canadian Arctic Archipelago where the air temperatures are, in turn, dependent on the altitude of the Sun. The upper curve of Fig. 1 shows the air temperature plotted against time of… (More)
