Estimation of dry bulk density of marine core sediments using an XRF core scanner

Abstract X-ray fluorescence (XRF) core scanners have advantages in nondestructive measurements of the elemental compositions of sediment cores with high stratigraphic resolution. To estimate elemental flux using sediment compositions measured by the XRF core scanner, total mass flux must be precisely calculated using the dry bulk density (DBD) and linear sedimentation rate records. In this study, we investigated a method for quantitatively estimating the DBD of sediment core samples with high re
