SOUTHAMPTON, ENGLAND—A high energy, high resolution CT scanner and visualization software are being used at the University of Southampton to create detailed, 3-D images of artifacts still encased in soil. This technology helps archaeologists plan ways to excavate fragile artifacts safely, or even to study them while keeping them in their protective layers of earth. Graeme Earl and Mark Mavrogordato of Southampton University and Alexandra Baldwin of the British Museum describe how the technology helped them analyze one of the 13 cauldrons unearthed in Chiseldon, Swindon, in this BBC video.
