Abstract:

Processed CT data of sediment core GeoB22346-3, performed using the ZIB edition of the Amira software (version 2021.08; Stalling et al., 2005), including CT image and interpretation of core sections, volume and percentage of matrix sediment, bioturbation and ice-rafted detritus, number of ice-rafted detritus clasts, number of ice-rafted detritus per cubic centimeter, and the mean, minimum and maximum of x-ray attenuation of matrix sediment.
