Abstract :
The macroscale (mm-to-cm) density structure was determined for sea-floor sediment cores from Eckernforde Bay (western Baltic Sea) using a modified computed tomography (CT or CAT) scanner. The vertical distributions of selected statistical CT parameters reveal the existence of tiers, and a conceptual model is presented to relate sediment macrostructure, physical property variability, and environmental processes. This characterization of the seafloor should prove useful in modeling high-frequency sound-sediment interactions, as well as, assist in a variety of other scientific and engineering investigations
