Abstract

A video-sediment-profile camera system for in situ imaging of bottom sediments has been used in Lake Superior and to probe burbot biogenic structures and on the upper continental slope off southern New England to dissect red crab burrows. The equipment and technique are described. Two image sequences have been analyzed for contrast and dynamic range, and then contrast enhancement and histogram equalization have been applied to enhance sedimentary structures
