Fig. 7From: “N”-shaped Y/X coda spectral ratio observed for in-line-type OBS networks; S-net and ETMC: interpretation based on natural vibration of pressure vesselAverage Y/X amplitude spectral ratio (solid red curves) and logarithmic standard deviation (dotted red curves) at θ = θmax° obtained for 12 selected S-net stations with different D1max, amongst those installed at water depths deeper than 1500 m. The θmax and D1max values for each station are written at the top and inside of each subfigure, respectivelyBack to article page
