P-wave velocity, wet bulk density, and magnetic susceptibility are measured on the whole CRP-1 core to analyse their down-core patterns and relationships with lithology, and to interpret the compaction and exhumation history. Velocity and density-based porosity are inversely correlated and strongly dependent on compaction and lithology. Fractional porosities of sands, silts and muds exhibit a nearly linear compaction trend from 0.5 to about 0.2 between 20 and 120 metres below sea floor (mbsf). This anomalously steep gradient suggests that overconsolidation of the lower portion is more important than the effects of lithology. Correction of porosities for both grain-size effects and the compaction trend implies overconsolidation even for some non-diamict units, probably related to glacial loading during deposition of overlying basal tills. Exhumation of the Miocene section, now unconformably overlain by Quaternary sediments above 43.15 mbsf, is estimated to be between 200 and 700 m based on different compaction trends. The down-core trend of magnetic susceptibility is largely independent of compaction and lithology. A relatively abrupt up-core increase in magnetic susceptibility from about 200 to more than 2 000 (10-6 SI) occurs at 63.2 mbsf, probably related to the onset of volcanic activity of McMurdo Volcanic Province at 19 Ma. Magnetic susceptibility below 63.2 mbsf is cyclic on a scale of tens of metres and correlates with the sequence stratigraphy of CRP-1. High frequency oscillations of magnetic susceptibility appear mostly as distinct spikes rather than cycles. The only exception is susceptibility cycles in the lowermost mudstone unit, where Milankovitch forcing is possible but remains questionable. A cluster analysis log calculated from physical properties does not match lithological unit and sequence boundaries, which indicates as-yet-unidentified petrophysical variations at CRP-1.
