Geochmical data form RV Meteor cruise M157 to the Namibian shelf, site GeoB23817-12, are presented here. Sediments were retrieved by 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.The Silicon (Si) content in gravity cores was measured using the X-ray fluorescence (XRF) Core Scanner II (AVAATECH Serial No. 2) at the MARUM - University of Bremen.
