Solid phase geochemical data, 14C ages and sedimentary data based on Computed Tomography (CT)-scans from three sites (GeoB23812, GeoB23814, GeoB23817) form RV Meteor cruise M157 to the Namibian shelf are presented here. Sediment cores were taken by using multicorer and gravity corer. Both, depth in core (cm) and a corrected depth below seafloor (cm) are presented for gravity core and the paired multi core from each site. Gravity core depths were adjusted to extend the paired multicore from the site. The offset was determined visually, based on eight pore water constituent profiles.For the analysis of element contents in marine sediments samples were freeze-dried and homogenized prior to digestion. Sediment samples were dissolved using a microwave digestion using an HCl-HNO3--HF acid cocktail as described in (Kossack et al., 2023; Scholz et al., 2011). Aliquots of the digested samples were analyzed via inductively coupled plasma optical emission spectroscopy (ICP-OES, VARIAN Vista PRO) in the Sediment Geochemistry Laboratory at MARUM in Bremen (major and selected trace elements: Al, Ti, Ca, Fe, K, Mg, Na, P, Ba, Cu, S, Sr, B and Zr) and mass spectrometry (ICP-MS) at GEOMAR Helmholtz Centre for Ocean Research Kiel (trace elements: Co, Mo, Th, U, and rare earth elements).The Silicon (Si) content in gravity cores was measured using the XRF Core Scanner II (AVAATECH Serial No. 2) at the MARUM - University of BremenFor total organic carbon (TOC) analysis in gravity core samples was performed at the Marum in Bremen. Therefore, 0.5g - 1g of dried sediment was decalcified by adding an excess amount of 10% HCl. Afterwards, the pH was raised to phH = 5 by adding distilled water, centrifuging and decanting. For the measurement 5mg freeze dried subsample were weighed into tin cups. Duplicate measurements were performed using a setup including a Flash EA 2000 Autosampler and Elemental Analyzer coupled to a Delta-V Plus Isotope Ratio Mass Spectrometer via ConFlo IV. TOC data from multi core samples were reported by (Chuang et al., 2022) and are included to complete the dataset.14C analysis on TOC were carried out in the Carbon Dating Laboratory at Alfred-Wegener-Institute (MICADAS – AWI) in Bremerhaven, Germany, by using accelerator mass spectrometry (AMS). The conventional AMS 14C ages were calibrated using the program: Calib Rev 8.1.0 (Stuiver & Reimer, 1993) with the calibration curve: marine20 (Heaton et al., 2020) and a marine carbon reservoir correction (ΔR) of 146 ± 85 14C years (Dewar et al., 2012).For CT-scans the gravity cores were kept in PVC liners 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 scans have 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).
