Abstract:
Computed Tomography (CT)-scan data form RV Meteor cruise M157 to the Namibian, site GeoB23812-25 are presented here. Sediments were recovered using gravity coring. Both, depth in core (cm) and the corrected depth below seafloor (cm) are presented. Gravity core depth was adjusted to extend the paired multicore from the site. The offset was determined visually, based on eight pore water constituent profiles.
For CT-scans the gravity core was kept in PVC liner and scanned using a Toshiba Aquilion 64™ Computed Tomography (CT) scanner at the hospital Klinikum Bremen-Mitte, with an X-ray source voltage of 120 kV and a current of 600 mA. The CT scan has a resolution of 0.351 mm in x- and y-direction and 0.5 mm resolution in z-direction. The z-direction represents the depth along the core axes, while x and y are perpendicular to the core axes (reconstruction interval: 0.3 mm). The obtained CT data were processed using the Amira ZIB edition software version 2017.39 (Stalling et al., (2005); http://amira.zib.de).
