Abstract:

The experiments described in this report were developed to test and evaluate prototype tools and advanced techniques to predict geologic conditions on the sea floor. Emphasis has been placed on determining the mass physical properties of sea-floor sediments and rocks using geophysical tools for the identification of associated parameters. A direct current resistivity system, was successfully developed. It is feasible to use electromagnetic sounding to measure conductivity and thereby deduce porosity at shallow depths below the sea floor-water interface. A seismic shear wave generator prototype tool was built and successfully tested to produce the transverse wave form in saturated marine sediments.
