Mean grain sizes of sortable silt were measured in two drilled cores (1124A and 1124B). Chronostratigraphy of core 1124 was correlated with the well-dated nearby core S931, resulting that the age of core 1124 covers the late Pleistocene spanning about MIS (Marine Isotope Stage) 5. Mean grain size of sortable silt seemed to be relatively large during the glacial period, whereas that of the interglacial period was smaller, although several tephra layers contain some coarse-grained pyroclastic particles. The variation in mean grain size of sortable silt in Rekohu sediment drift during the late Pleistocene indicates that the intensity of Deep Western Boundary Current (DWBC) might have been enhanced during the glacial period as a result of increased production of Antarctic Bottom Water (AABW).completedQuaternary geologyAntarctic Bottom WaterCenozoicclastic sedimentscurrentsglacial environmentintensityinterglacial environmentLeg 181marine environmentmarine transportocean currentsOcean Drilling ProgramODP Site 1124Pacific Oceanpaleo-oceanographyPleistoceneQuaternaryRekohu sediment driftsediment transportsedimentssiltSouth PacificSouthwest Pacificterrestrial environmentupper PleistocenevariationsWest Pacificurn:org.iodp:exp:181urnlargerWorkCitationcampaignurn:org.iodp:exp:181:site:1124urnlargerWorkCitationstudyurn:org.iodp:exp:181urnlargerWorkCitationcampaignKoreangeoscientificInformation-176.3154-176.3154-39.2954-39.2954
