Figure 15. Map showing two seismic survey tracklines overlying a color-shaded relief image of Red Brook Harbor, Massachussets, bathymetry. Both tracklines (A1-A2 and B1-B2) were run from west to east. Corresponding seismic profiles show subsurface channels underlying the present-day channel floor. The x-axis in the seismic profiles is shown in shot points, and the y-axis is two-way travel time in seconds.
