Terra Antartica, 5(3), 291-297, hdl:10013/epic.28342.d001 Abstract: 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 density permit conversion of the whole-core density record to porosity. Agreement between our magnetic susceptibility measurements and the continuous, whole-core data is excellent. In contrast, our atmospheric pressure measurements of P-wave velocity are ~10% faster than whole-core data obtained at the same pressure. Our measurements of velocity versus pressure indicate that in situ P-wave velocities are probably only 1-3% higher than those measured at atmospheric pressure. Although the Miocene section has undergone significant exhumation, we do not observe typical exhumation signatures of anomalously low initial velocities followed by microcrack closing as pressure is increased. Instead, velocity response to pressure appears to be dominated by a small amount of post-exhumation cementation.
