ODP Expedition 178, Site 1101, X-ray image logger (XSCAN) images

The dataset contains digital X-ray images of marine sediment cores from Ocean Drilling Program (ODP) Leg 178, Site 1101. Cores 1101A-1H to 24H were scanned using the IODP X-ray Image Logger (XSCAN) at the Gulf Core Repository at Texas A&M University in January–February 2023, just after the XSCAN instrument had been commissioned and before it was shipped out to the laboratory aboard the JOIDES Resolution research vessel. ODP Site 1101 lies to the west of the Antarctic Peninsula at 64° 22.3314' S, 70° 15.6708' W, in 3291 m water depth (Barker et al., 1999, Cowan et al., 2001). We took X-ray scans to investigate ice-rafted debris (IRD) at this site in the late Pliocene to early Pleistocene (Mossell, 2025). IRD is evident as dark spots in the images (dark colors represent dense material). Cracks developed in the cores over the 25 years since the cores were drilled; these cracks are evident as pale linear features in the X-ray images.
