Abstract:
Solid phase geochemical data form RV Meteor cruise M157 to the Namibian shelf, site GeoB23817, are presented here. Sediment cores were taken by using a 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. Gravity core depth was adjusted to extend the paired multicore. 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 (Al and Zr) and mass spectrometry (ICP-MS) at GEOMAR Helmholtz Centre for Ocean Research Kiel (trace elements: Mo and U).
