| Abstract: | A calibration procedure is presented for generating bulk density profiles of intact marine sediment cores using X-ray computed
tomography (CT). Developed using both artificial and natural marine sediment samples, the correlation is strong with an R
2 value of 0.98. Similar experiments with carbonate sediments were also strongly linear, but offset from the terrigenous curve,
illustrating the influence of sediment chemistry on scanner response. Comparison between newly computed densities for both
sediment types with those from individually calibrated cores during our previous CT studies reveals good correspondence between
the data sets.
