Petrophysical measurements on core plug samples of sediment core CRP-1 (Table 1) ...
This paper reports measurements of velocity vs pressure and of bulk density, porosity, matrix density, and magnetic susceptibility in 18 core plugs from CRP-1. Comparison of our bulk densities with continuous whole-core density records shows very good agreement. Core-plug measurements of matrix dens...
