Sample SaM-ID43148 was retrieved during Meteor cruise M70-1 with the ROV MARUM-Quest from the Gondola Slide, southeast of the Gargano Promontory in the Adriatic Sea (Station M70/1-752, GeoB11207, 41°43.51'N, 17°02.78'E, 710 m water depth). The specimen was scanned with a Philips Brilliance iCT Elite 256 computer tomograph (x-ray source, voltage: 120 kV; current: 300 mA; physical resolution: 0.313 in xy-direction, respectively, 0.625 mm in z-direction; re-construction interval in z-direction: 0.3 mm; reconstruction: filtered Back Projection (fBP) mode and a bone kernel (YB (Enhanced)). Polyp-cavity (calice) segmentation was perfromed with the ZIB edition of the Amira software (Stalling et al., 2005; http://amira.zib.de) based on the new method describes in Schmitt et al. (submitted).
