High-resolution petrophysical data, acquired using the multisensor core logger (MSCL), comprise a valuable component of the data obtained from this sedimentary record. However, the nondestructive measurements performed using the MSCL are highly dependent on core quality and sensor calibration. Quality control on bulk density measurements from the MSCL is routinely provided by comparison with direct measurements of bulk density (rho (sub B) ) performed at coarser resolution on discrete samples. Here, results from these discrete analyses are used to correct rho B measurements from the MSCL. The method and rationale for these corrections are outlined in this study, and the corrected MSCL rho B records are presented. Using the corrected records, high-resolution dry density (rho (sub D) ) and porosity (phi ) logs are generated, providing a means for determining mass accumulation rates and investigating lithology-dependent compaction processes in central Arctic Ocean sediments.completedOceanographyArctic Coring EXpeditionArctic OceanboreholescoresdensityExpedition 302high-resolution methodsIntegrated Ocean Drilling ProgramIODP Site M0001IODP Site M0002IODP Site M0003IODP Site M0004Lomonosov Ridgemarine sedimentsphysical propertiesporositysedimentsspatial variationswater contenturn:org.iodp:exp:302urnlargerWorkCitationcampaignurn:org.iodp:exp:302:site:M0001urnlargerWorkCitationstudyurn:org.iodp:exp:302urnlargerWorkCitationcampaignurn:org.iodp:exp:302:site:M0002urnlargerWorkCitationstudyurn:org.iodp:exp:302urnlargerWorkCitationcampaignurn:org.iodp:exp:302:site:M0003urnlargerWorkCitationstudyurn:org.iodp:exp:302urnlargerWorkCitationcampaignurn:org.iodp:exp:302:site:M0004urnlargerWorkCitationstudyurn:org.iodp:exp:302urnlargerWorkCitationcampaignEnglishgeoscientificInformation136.1100139.320087.520087.5600
