a The results of the velocity analysis with an NMO-velocity of 1520 m/s. Every two NMO gathers are plotted. Most gathers appear to be appropriately corrected, with a few exceptions of shot points 29–33. SF represents seafloor. b The results of the velocity analysis with an NMO-velocity of 1580 m/s. Every two NMO gathers are plotted. The NMO gathers of shot points 29–33 are appropriately corrected, meaning that the true velocity is 1580 m/s. SF represents the seafloor. c Conceptual diagrams of NMO corrections with true, lower, and higher velocities are displayed
