LONG-TERM GOALS. To improve our understanding of the relationships between sedimentary physical properties and geophysical parameters. To establish methodologies for the joint interpretation of independent geophysical data sets. OBJECTIVES. Ambiguity in interpretation of geophysical data in terms of seafloor physical properties can be reduced if independent and complementary data sets are examined together. However, opportunities to carry out such analyses are rare. A cruise completed in 1998 featured coincident measurements of electrical resistivity and shear wave velocity across a series of buried paleo-channels on the New Jersey continental shelf. We propose to combine analyses of these two independent measures of seafloor structure to provide greater insight into the nature of the channels both in terms of the infilling material and the contrast in physical properties across the channel walls.
