IODP Site U1537 U-Channel CT Scan DICOM Data, SedCT Output, and HU Values

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. Antarctic Response to Orbital Forcing During the Intensification of Extensive Bipolar Glaciation (1.75–3.30 Ma) From Relative Paleomagnetic Intensity Stratigraphy of the Dove Basin, Scotia Sea. Paleoceanography and Paleoclimatology 41, e2025PA005360. https://doi.org/10.1029/2025PA005360 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. U1537A SedCT Output.zip CT#s, unscaled TIFF files, and PNG files scaled to 200-1400 HU for U1537A u-channels generated using SedCT Matlab Tools. U1537D SedCT Output.zip CT#s, unscaled TIFF files, and PNG files scaled to 200-1400 HU for U1537D u-channels generated using SedCT Matlab Tools.
