Computed tomography (CT) scans of sediment cores collected during the PETERMANN15 expedition of the Swedish Icebreaker Oden, OD1507 included cores 03 Trigger Core (TC), 03 Piston Core (PC), 04 Gravity Core (GC), 06PC, 08GC, 10PC, 10TC, 40PC, 40TC, and 41GC. Data include 2 millimeter (mm) thick coronal slices in Digital Imaging and Communications in Medicine (DICOM) format and SedCT products (software for sediment cord CT processing), including images and CT numbers. CT data were collected to image the 3-dimensional density structure of the sediment cores to study sedimentary structures, lithofacies, and ice rafted debris. This information provides information on the glacial history of Petermann Fjord and provides stratigraphic context for other data generated from these cores. CT scans were collected of the sediment cores at the Oregon State University School of Veterinary Medicine in 2016 after arriving at the Oregon State University Marine and Geology Repository. These data are further discussed by Reilly et al., 2019, Holocene break-up and reestablishment of the Petermann Ice Tongue, Northwest Greenland, Quaternary Science Reviews, doi: 10.1016/j.quascirev.2019.06.023.
