Figure 10. Clips from digital terrain models of the sea floor produced from the combined multibeam and LIDAR bathymetric data collected during National Oceanic and Atmospheric Administration surveys H11442 and H11225 off Niantic, Connecticut: (A) Unadjusted bathymetry showing artifacts caused by the multibeam dataset being shallower than the corresponding LIDAR bathymetry, and (B) image showing the same area of the sea floor after the multibeam dataset was adjusted 25 cm deeper. (Location of clips is shown in figure 3.)
