The sediment series recovered during METEOR Cruise M 46/4 with the gravity corer were subject to laboratory geophysical studies. Shipboard measurements on the segmented cores routinely comprised three basic physical parameters: - compressional (p-) wave velocity vp, - electric resistivity Rs (as a measure of density and porosity), and, - magnetic volume susceptibility K.These properties are dosely related to lithology and grain size of the sediments and provide highresolution care logs (spacing 1 cm for p-wave velocity, 2 cm for electric resistivity and magnetic volume susceptibility) available prior to all other detailed investigations. In addition, oriented sampies for subsequent shore based rock and paleomagnetic studies were taken at typically 5 cm intervals.
