A new system for logging the geophysical properties of marine sediment cores allows both whole cores and split cores to be measured in a nondestructive fashion. The current sensor configuration measures compressional (P) wave velocity (500 kHz), bulk density (using gamma-ray attenuation), and magnetic susceptibility at user-defined sample intervals down the core. Split-core logging gives more reliable results than whole core logging as it mostly eliminates core-slumping effects that can lead to spurious results; it also gives higher resolution magnetic susceptibility readings.
