P-wave velocity, resistivity, and magnetic susceptibility measurements are affected by room and core temperature. In terms of sensor precision, gamma density and magnetic susceptibility sensors are affected by the duration of each point measurement. In sections where the core liner is not filled or the core is insufficiently saturated, the measurement quality is compromised. Optimal measurements for all sensors require a completely filled core liner and fully water-saturated cores for P-wave velocity and gamma density measurements. Core catcher pieces were not included in the logging process.Дata quality is a function of both core quality and sensor precision.

Standard mode measurements were taken on all core sections except for cores below Core 313-M0029A-173R (see ' P-wave velocity') after they were equilibrated to ambient temperature. Whole-round core sections were measured with the MSCL set up in horizontal mode. Two secondary measurement sensors are also present that allow these primary measurements to be corrected for core diameter and temperature. The MSCL has four primary measurement sensors mounted on an automated track that sequentially measure gamma density, P-wave velocity, NCR, and magnetic susceptibility. This allowed independent determination of bulk density, dry density, grain density, water content, porosity, and void ratio, all of which were used to calibrate the high-resolution, nondestructive measurements made offshore on whole cores with the MSCL.

A helium gas pycnometer was used to measure the volume (for density determinations) of discrete samples at an approximate resolution of one per core section from the working half of split cores. Discrete P-wave velocities were mostly measured at the same depth as MAD determinations at an approximate resolution of one per core section from the working half of split cores. Lower resolution measurements of thermal conductivity on unsplit cores using a full-space needle probe prior to the OSP and on samples extracted from cores split and measured during the OSP for discrete P-wave velocities and moisture and density (MAD) were routinely performed manually. Onshore, petrophysical measurements included NGR (measured on whole-round cores prior to the OSP), digital line scan images, and color reflectance (split cores during the OSP). Note that 'gamma density' refers to the bulk density of the core as derived from the collimation of gamma rays across the core (see 'Gamma density'). The MSCL was outfitted with four sensor types in order to measure gamma density, transverse compressional wave ( P-wave) velocity, noncontact electrical resistivity (NCR), and magnetic susceptibility. Offshore, the petrophysics program involved collecting high-resolution, nondestructive measurements on whole cores using a Geotek MSCL. Provide data for post-OSP construction of synthetic seismograms and investigation of the characteristics of major seismic reflectors.
