7. Echo integration in low signal to noise regimes: methods of noise estimation and removal

   Abstract:  The results of acoustic surveys, especially in low signal-to-noise regimes, are ... sensitive to the method used to exclude the contribution of background noise from the acoustic data. The use ... of thresholds to reject weak signals during data collection is inappropriate because the noise ... contribution to the above-threshold-signal cannot later be removed in post processing. The only solution is to ...
