X-ray computed tomography scans have been used to look inside drill cores without destroying them. On the drilling vessel Chikyu, drill cores are routinely scanned by X-ray computed tomography, but the usage of scan data has been limited on the vessel due to large data size, unfamiliar data format, etc. In this study, we designed a workflow that enables shipboard scientists to access and utilize the X-ray computed tomography data quickly for shipboard core handling.
