| contents | Physical properties of core PS87_030_KAL were retrieved onboard RV Polarstern during expedition PS87 using a Geotek Multi-Sensor Core Logger MSCL-S. Processing of p-wave velocity data included calibration using a water-filled liner. Density data were calibrated by measuring an aluminum-water calibration piece. Porosity is inferred from density using a mean grain density of 2.75 g cm-3 and a water density of 1.026 g cm-3. Magnetic susceptibility data were measured using a loop sensor with a diameter of 140 mm. For correction of low magnetic susceptibility values at core ends, short liner pieces were always measured before the first and after the last section, respectively. Values measured in these two pieces were added to the reduced values measured at the core ends. Volume correction was performed using a value of 0.555. Drift correction was carried out for magnetic susceptibility measurements using a linear regression. All data were cleaned for outliers. This publication contains data from Lomonosov Ridge, Central Arctic. |
