### Morphological Analysis of Submarine Channels  
Type 1 of the channel complexes narrows in a down-dip direction across the study area, where the top width decreases from 3821 to 2612 m (Table 1, Figures 4 and 8a). This linear trend is represented by relatively high correlation and determination coefficients (R and R\({}^{2}\)), respectively (Table 1). These indicate that the decrease in the top width is proportional to the down dip distance. In parallel, the base width of Type 1 also decreases to the end of its western part, with an average base width of 436 m (Figure 8b). In contrast, the height of Type 1 ranges from 274 to 320 m and has a relatively flat trend through the channel distance (Figure 8c), indicated by low values of R and R\({}^{2}\) (0.42 and 0.18, respectively (Table 1). The CSA of Type 1 increases from 0.04 to 0.07 km\({}^{2}\) in a down-dip direction (Table 1 and Figure 8d). The Type 1 sinuosity values increase from straight (average 1) in the beginning of the western area to low sinuosity (average 1.05) at the end of the western area (Table 1 and Figure 8e). In parallel, the aspect ratio of Type 1 decreased from 12.90 to 8.90 down dip (Table 1 and Figure 8f). Type 2 has a top width ranging from 1690 to 2257 m with non-linear trends (Table 1, Figures 4 and 8a). This trend is represented by relatively low values of correlation and determination coefficients (R and R\({}^{2}\)), respectively (Table 1). These indicate that decreases in top width are not proportional to down-dip distance. In parallel, the base width of Type 2 is also in a non-linear trend through the length of the channel (Figure 8b), with an average value of 327.6 m (Table 1 and Figure 8b). The height of Type 2 ranges from 208 to 242 m, with relatively low values of correlation coefficients and determination (R and R\({}^{2}\), respectively. See Table 1). The CSA of Type 2 ranges from 0.04 to 0.07 km\({}^{2}\), with no trend of the CSA through the channels' distance (Table 1 and Figure 8d). The sinuosity increases from low sinuosity (average 1.02) at the beginning of the western area to high sinuosity (average 1.30) at the end of the western area (Table 1 and Figure 8e). In addition, the aspect ratio of Type 2 has minimum and maximum values of 7.40 and 9.80, respectively, with no trend-down dip (Table 1 and Figure 8f). \begin{table}
