Magnetic volume susceptibility k is the ratio of sample magnetization change per applied external magnetic field change. It is unitless in the SI unit system, which we signalize by the letters 'SI' after the ratio value. Magnetic volume susceptibility k was measured on all full cores at increments of 2 cm using a shipboard GEOTEK Multi Sensor Core Logger (MSCL) equipped with a Bartington M.S.2 susceptibility meter and a 140 mm loop sensor. Sharp lithology changes (e.g. ash layers, dropstones) are smoothed in these susceptibility data due to the coil-size related averaging over a core interval of about 8 cm (halfwidth of sensor characteristic).
