Abstract:

REMOTS(REGISTERED TRADEMARK) technology, a combination of sediment-profile photography and computer image analysis, was developed to address shortcomings in traditional benthic sampling methodology. The camera design allows undisturbed in-situ profile images of the top 15-20 cm of sediment to be obtained rapidly; organism-sediment relationships are preserved, and the system is never affected by water turbidity, allowing images to be obtained anywhere. Recent advances in understanding the dynamics of infaunal community structure has led to the development of a theory of image interpretation, making REMOTS(REGISTERED TRADEMARK) a powerful benthic sampling tool. Using REMOTS(REGISTERED TRADEMARK), one can deduce the dynamics of biological and physical seafloor processes from imaged structures. As part of the Puget Sound Dredge Disposal Analysis (PSSDA) baseline characterization of potential dredged material disposal sites, Science Applications International Corporation (SAIC) conducted REMOTS(REGISTERED TRADEMARK) surveys at four sites in Puget Sound during November 1985. A total seafloor area of thirteen square nautical miles was surveyed in 5 field days; analysis, interpretation, and a final report were completed in two weeks following completion of the field sampling.
