Figure 17. Acoustic backscatter registered in the Northwestern (NW) transect. Data are presented as median volume backscattering (Sv in dB) values (11 ping running median) in the surface, middle and bottom layers. Distance to windfarm is in the x-axis. Columns 1 and 2 represent the two replicate transects. Dashed light grey lines are the 25th and 75th quantiles.
