Description
Computed Tomography (CT) Data Collected on IODP Site U1537 u-channel samples using the Oregon State University College of Veterinary Medicine Toshiba Aquillon 64 Slice Medical CT Scanner in collaboration with the Oregon State University Marine and Geology Repository. U-channels were measured in batches of 8 with derived CT data selecting only a portion of these original files for each u-channel. All data are archived in DICOM format and have been processed using SedCT Matlab Tools (Reilly et al., 2017; 10.1002/2017GC006884). Data are reported and descriped by Reilly et al. (2026).
Files Include:
U1537 U-Channel CT DICOM Files (Original).zip
Data in DICOM format from original scans measured in batches of 8. Includes excel spreadsheet with identifying information for which sections were measured in each scan.
U1537A U-Channel CT DICOM Files (Split).zip
Data in DICOM format, segmented so each u-channel is a sperate file. Folder system organized by section with two subfolders included for scans that needed to be run in two scans (nominally sections longer than 1 m). Includes U1537A sections: 24H-2A, 24H-3A, 24H-4A, 25H-3A, 25H-4A, 25H-5A, 25H-6A, 26H-2A, 26H-3A, 26H-4A, 26H-5A, 26H-6A, 26H-7A, 26H-8A, 27F-3A, 2F-4A.
U1537D U-Channel CT DICOM Files (Split).zip
Data in DICOM format, segmented so each u-channel is a sperate file. Folder system organized by section with two subfolders included for scans that needed to be run in two scans (nominally sections longer than 1 m). Includes U1537D sections: 24H-1W, 24H-2W, 24H-3W, 24H-4W, 24H-5W, 24H-6W, 25H-1W, 25H-2W, 25H-3W, 25H-4W, 25H-5W, 25H-6W, 25H-7W, 26H-5W, 26H-6W, 26H-7W, 27H-2W, 27H-3W, 27H-4W, 27H-5W, 27H-6W, 27H-W, 28F-1W, 28F-2W, 28F-3W, 29F-1W, 29F-2W, 29F-3W, 29F-4W, 30F-1W, 30F-2W, 30F-3W, 30F-4W, 31F-1W, 31F-2W, 31F-3W, 31F-4W.
