Paleomagnetic directions suggest that the sedimentary sequence from 0 to 59.6 m composite depth (mcd) covers geomagnetic polarities from 0 to 3.6 Ma. Although high fluctuations of magnetic mineral concentrations in most studied intervals are inadequate for a relative paleomagnetic intensity (RPI) study, proxies of RPI in the interval 16.9-46 mcd, which is relatively constant in magnetic mineral concentrations, represent an RPI pattern similar to previous North Atlantic data. This similarity suggests good potential for further age control using RPI on sediments from Site U1312.completedQuaternary geologyanhysteretic remanent magnetizationAtlantic OceanboreholesCenozoicchemostratigraphycorescorrelationDeep Sea Drilling ProjectDSDP Site 608event stratigraphyExpeditions 303/306Integrated Ocean Drilling ProgramIODP Site U1312IPODisotope ratiosisotopesKing's TroughLeg 94magnetic inclinationmagnetic intensitymagnetic propertiesmagnetic susceptibilitymagnetizationmarine sedimentsnatural remanent magnetizationNorth AtlanticNortheast AtlanticO-18/O-16oxygenpaleomagnetismPleistoceneQuaternaryremanent magnetizationreversalssedimentsstable isotopesurn:org.iodp:exp:94urnlargerWorkCitationcampaignurn:org.iodp:exp:94:site:608urnlargerWorkCitationstudyurn:org.iodp:exp:94urnlargerWorkCitationcampaignEnglishgeoscientificInformation-23.0500-23.050042.500042.5000Supplemental information/data is available in the online version of this articleapplication/pdfunknownSEDIS Publication Catalogue
