Table 1: The parameters estimated in the study area. The range of the geoacoustic parameters \((c_{0},K)\) in which the normalized \(F(c_{0},K,H_{2})\) is >0.95 of its maximum level, \(F_{0.95}\), represents the estimation error. FFID is a Field File Identification Number, i.e., the source gather number. The thickness of the sub-bottom layer \(H_{2}\) varied from 700 to 1300 m and decreased with bottom depth, which agrees with the depth-migrated seismic section crossing the study area (Figure 4a). Neither the seafloor velocity \(c_{0}\) nor the depth of the salt layer \(H_{2}\) seemed to correlate to the velocity gradient \(K\) (Figure 11c,d). This reinforces our assumption that there is no inter-dependence on the geoacoustic estimations. The spatial distribution of the estimated values (Figure 12) demonstrates the consistency of the parameters and their variations between the different seismic lines.
