Moisture and density (MAD) measured on IODP Hole 317-U1352C

Geocode = Depth CSF-A (m). MAD data are acquired on ~10 mL sediment or rock subsamples by measuring three out of four material parameters: wet (saturated) mass and/or volume, and dry mass and/or volume after 24 h drying in a convection oven. The combination of measurements is defined by the submethod (A, B, C, D). Wet (A, B, C) and dry (A, B, C, D) mass is determined using motion-compensated signals from commercial Mettler-Toledo balances. Wet volume (A, B, D) is determined by the sample's geometric dimensions using calipers. Dry volume (C, D) is measured by helium pycnometry. Submethods A and B are not recommended by IODP). Submethod C is suitable for saturated materials such as fine-grained sediments. Submethod D is suitable for unsaturated porous material such as certain limestones and basalts. From the moisture and volume measurements, the following phase relationships are calculated: wet and dry water content, wet bulk density, dry bulk density, grain density, porosity, and void ratio.
