Rapid coastal survey of anthropogenic radionuclides, metals, and organic compounds in surficial marine sediments

A towed survey system, the GIMS/CS3, has been developed to enable the rapid measurement and mapping of a variety of physical and geochemical parameter s in the surficial sediments of aquatic environments while the survey vesse l is underway. With its capability for measuring radiometric, elemental and organic compound constituents of sediments, as well as bathymetry and wate r quality parameters, the GIMS/CS3 provides a cost-effective means of perfo rming reconnaissance determinations of contaminant distributions and enviro nmental monitoring tasks over broad geographic regions.
