Abstract:As part of SAX 99, a multi-investigator study focused on the penetration and scattering of high-frequency (10–300 kHz) sound in marine sediments, two independent measurements of sediment volume heterogeneity (SVH) were made. The first tool used to measure SVH was an in situ resistivity profiler (IRP) that logs sediment resistivity at 0.25-mm vertical intervals to depths of 15 cm. Robust empirical calibrations are used to calculate sediment porosity. The second method used to measure SVH was a digital x-ray sys… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
