Overview

The Physical Properties Lab measures magnetic susceptibility, density, P-wave velocity, natural gamma radiation (NGR), moisture content, thermal conductivity, and visible spectral reflectance of rocks and sediments and captures a digital image of the split-core sections. Physical properties are indicators of composition, formation, tectonic regime, and environmental conditions of the deposits. Some properties can be measured rapidly at high spatial resolution and serve as proxies for processes such as paleoclimatic change. 

Moisture and Density (MAD)

Multisensor Loggers (WRMSL and STMSL)

The Whole-Round Multisensor Logger (WRMSL) and Special-Track Multisensor Logger (STMSL) are similar track systems for measuring the magnetic susceptibility, density, and P-wave velocity of whole-round core sections. WRMSL and STMSL used identical software and hardware from Expedition 371 up to Expedition 379. During Expedition 379 (January 2019), the P-wave velocity logger (PWL) was removed from WRMSL and replaced with an interchangeable X-ray system. STMSL is now the primary multisensor logger and WRMSL can be used either as an X-ray system or for additional measurement of magnetic susceptibility and density on expeditions that need those data for rapid stratigraphic correlation between drill holes.
