Physical properties measured on 21 sediment cores from METEOR cruise M23/1

During METEOR Cruise M23/1 the recovered gravity and piston cores were subject to laboratory geophysical studies. A routine shipboard measurement of three physical parameters was carried out on the segmented sediment cores, comprising the determination of - the compressional (P-)wave velocity vp, - the electric resistivity Rs, and -the magnetic volume susceptibility k.

These properties are closely related to the grain size, porosity and lithology of the sediments and provide high-resolution core logs (spacing 2, 2 and 1 cm, respectively) available prior to all other detailed investigations. In addition, oriented sampies for later shore based paleo- and rockmagnetic studies were taken at intervals of 10 cm.

Compared to reports of previous METEOR cruises the data presentation of the physical properties section has been slightly modified. The three parameters vp, wet bulk density Owet and k are now displayed in a constant 1 : 50 depth scale. This new format was defined in cooperation with the geological working group and considerably faciliates a direct comparison of core descriptions and logging data.
