Meet the physical property and downhole measurement specialists of Expedition 355. These scientists measure physical properties of the cores and the borehole walls to provide information about things like density, porosity, magnetic susceptibility, and acoustic velocity. These properties are indicators of composition, formation, tectonic regime, and environmental conditions of the deposits.
