CT analyses

Computed tomography (CT) is commonly used in geosciences for the visualisation of sedimentary structures, bioturbation traces, bioerosion traces, fossil microstructure, pore networks, etc. Also quantitative approaches get increasingly important. My main research interest is the quantification of visual observations ranging from clast-size and clast-orientation analyses of cold-water coral fragments in gravity cores to intrapore space classification and quantification analysis.
