Abstract : Ambient noise was measured from R/V CHAIN at three stations in the eastern North Atlantic Ocean. Figures showing the temporal variation of ambient noise and wind speed are given. Passing ships, biological sources, and changes in the status of CHAIN's machinery are noted. There appeared to be little if any effect from the latter two sources. For each station frequency, and depth, distribution curves of ambient noise and station averages are given. The levels and spectra were those that might be expected for areas of very high shipping, and varied from area to area in a manner consistent with the estimated shipping density. There was little or no correlations with wind speed. (Author).
