Summary: Three sites on and near Challenger Mound, a carbonate mound structure covered with dead deepwater coral rubble in Porcupine Seabight on the southwest Irish continental margin, were drilled during Integrated Ocean Drilling Program Expedition 307 in May 2005. In addition to the mound, one site immediately downslope of Challenger Mound and an upslope site were drilled to constrain the stratigraphic framework of the slope/mound system and to identify and correlate erosional surfaces. X-ray computerized tomography (CT) was used to image 6 m long half-round cores recovered from an off-mound site. X-ray CT visualizes three dimensional (3-D) distribution of X-ray linear absorption coefficients of samples and allows examination of 3-D measurements of complex shapes of corals fragments and dropstones in sedimentary sequences.
