The CT image stacks have a resolution of 0.35 mm in x/y-direction and 0.5 mm resolution in z-direction (0.3 mm reconstruction unit). Images were reconstructed using Toshiba's patented helical cone beam reconstruction technique (TCOT) and are provided in DICOM-format. The data were processed with the ZIB edition of the Amira software (version 2021.03; Stalling et al., 2005; http://amira.zib.de). Within Amira, the core liners, including about 2 mm of the core rims, were deleted from the data set. Mangan nodules with diameters >~1 mm, open bioturbation traces, an unidentified organism (only present in core SO268-2-200-1 MC18), the natural bioturbated and surficial homogenised sediment were segmented by a marker-based watershed segmentation and visualized in 3D. Subsequently, the sediment components were quantified (MaterialStatistics module; volume per slice) and the mean and standard deviation of the sediment x-ray attenuation (MaterialStatistics module; statistics per slice per label; to avoid marginal averaging effects the sediment label was reduced by three voxels) were determined.-125.922616714.01848333Clarion-Clipperton Fraction Zone, North East Pacific OceanFederal Ministry of Education and Researchhttps://doi.org/10.13039/50110000234703F0812AJPI-O MiningImpact: Monitoringkonzepte für einen Manganknollenabbau in der Tiefsee
