Screen capture of an intermediate stage of building the side-scan mosaic.  The blue lines and arrows show the bounds and port (red arrow) and starboard (green arrow) sides of the individual imagery files collected by Sentry.  At this stage, the outside edges of the individual images have been trimmed to remove parts of these data outside the visible range and the intensities of the acoustic returns have been compared and normalized.
