The two main objectives of this study were to determine if there exists a difference of isotopic compositions between the different sites and to characterize the isotopic signals that might be associated with the presence of gas hydrate at depth.completedIsotope geochemistryaragoniteauthigenic mineralsboreholesBritish ColumbiaC-13/C-12calciteCanadacarboncarbonatesCascadia subduction zonecoresdolomiteEast PacificExpedition 311gas hydratesgeochemistryIntegrated Ocean Drilling ProgramIODP Site 1325IODP Site 1326IODP Site 1327IODP Site 1328IODP Site 1329isotope ratiosisotopesmarine sedimentsmineral compositionNorth PacificNortheast PacificO-18/O-16oxygenPacific Oceansedimentsspatial variationsstable isotopesVancouver IslandWestern Canadaurn:org.iodp:exp:311urnlargerWorkCitationcampaignurn:org.iodp:exp:311:site:U1325urnlargerWorkCitationstudyurn:org.iodp:exp:311urnlargerWorkCitationcampaignurn:org.iodp:exp:311:site:U1326urnlargerWorkCitationstudyurn:org.iodp:exp:311urnlargerWorkCitationcampaignurn:org.iodp:exp:311:site:U1327urnlargerWorkCitationstudyurn:org.iodp:exp:311urnlargerWorkCitationcampaignurn:org.iodp:exp:311:site:U1328urnlargerWorkCitationstudyurn:org.iodp:exp:311urnlargerWorkCitationcampaignurn:org.iodp:exp:311:site:U1329urnlargerWorkCitationstudyurn:org.iodp:exp:311urnlargerWorkCitationcampaignEnglishgeoscientificInformation-127.0300-126.410048.380048.4700application/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://publications.iodp.org/proceedings/311/ERR/CHAPTERS/311_210.PDFdownload
