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.completedOceanographySedimentary petrologyAtlantic Oceanbiogenic structuresboreholescarbonate bankscarbonatesChallenger Moundcomputed tomography datacoresExpedition 307imageryIntegrated Ocean Drilling ProgramIODP Site 1316marine sedimentsmoundsNorth AtlanticNortheast AtlanticPorcupine Seabightsedimentary structuressedimentsX-ray dataurn:org.iodp:exp:307urnlargerWorkCitationcampaignurn:org.iodp:exp:307:site:U1316urnlargerWorkCitationstudyurn:org.iodp:exp:307urnlargerWorkCitationcampaignEnglishgeoscientificInformation-11.4400-11.440051.230051.2300application/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://publications.iodp.org/proceedings/307/ERR/CHAPTERS/307_209.PDFdownload
