Prior drilling at Deep Sea Drilling Project (DSDP)/Ocean Drilling Program (ODP)/Integrated Ocean Drilling Program (IODP) Sites 1256 and 504 provides evidence that the extrusive ocean crust has sufficient porosity and permeability to enable storage of large volumes of CO (sub 2) . Six intervals are identified as potential reservoirs in the shallow crust at Sites 1256 and 504, with new and reprocessed estimates of porosity from electrical resistivity logs ranging from 6% to 14% and permeability from approximately 10 (super -14) to 10 (super -15) m (super 2) . Calculations using specific reservoir thickness and porosity estimates suggest that even the smallest reservoir could provide storage capacity for decades of global anthropogenic carbon emissions. In situ hydrologic experiments and pilot injection studies are needed to confirm high permeability and porosity estimates at Sites 1256 and 504, as well as the potential for CO (sub 2) injection and retention in these basalt reservoirs.completedEngineering geologybasaltscarbon dioxidecarbon sequestrationCarnegie RidgeCocos RidgecrustDeep Sea Drilling ProjectDSDP Site 504East PacificEquatorial Pacificigneous rocksIntegrated Ocean Drilling ProgramLeg 148lithospheremid-ocean ridge basaltsNazca RidgeNorth PacificNortheast PacificOcean Drilling Programoceanic crustoceanic lithosphereODP Site 1256Pacific Oceansite explorationSouth PacificSoutheast Pacificvolcanic rocksurn:org.iodp:exp:148urnlargerWorkCitationcampaignurn:org.iodp:exp:111:site:504urnlargerWorkCitationstudyurn:org.iodp:exp:111urnlargerWorkCitationcampaignurn:org.iodp:exp:137:site:504urnlargerWorkCitationstudyurn:org.iodp:exp:137urnlargerWorkCitationcampaignurn:org.iodp:exp:140:site:504urnlargerWorkCitationstudyurn:org.iodp:exp:140urnlargerWorkCitationcampaignurn:org.iodp:exp:148:site:504urnlargerWorkCitationstudyurn:org.iodp:exp:148urnlargerWorkCitationcampaignurn:org.iodp:exp:206:site:1256urnlargerWorkCitationstudyurn:org.iodp:exp:206urnlargerWorkCitationcampaignEnglishgeoscientificInformation-91.5600-83.43481.13356.4400application/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://onlinelibrary.wiley.com/journal/10.1002/(ISSN)1944-8007/homepage/2013Special_Section_Proposal-form.pdfdownload
