Diatom abundance seems to be in interglacial stages and suggests a south-north shifting of the frontal area. Diatom temperature values are less reliable because frequency of the warm-water species is smaller. Site 1151 was in a warm climate at approximately 50 ka, as were Deep Sea Drilling Project Sites 579 and 580 in the western North Pacific Ocean. A mixed diatom assemblage in the upper 3 mbsf at Site 1150 is evidence that the Tsugaru Warm Current flowed into the studied area through the Tsugaru Strait.completedStratigraphyalgaeAsiabiostratigraphyCenozoiccorescorrelationcurrentsDeep Sea Drilling ProjectdiatomsDSDP Site 579DSDP Site 580Far EastHonshuinterglacial environmentIPODJapanLeg 186Leg 86marine environmentmarine sedimentsmicrofossilsNeogeneocean currentsOcean Drilling ProgramODP Site 1150ODP Site 1151paleo-oceanographypaleoclimatologypaleocurrentspaleotemperaturePlantaereconstructionSanrikusedimentsTertiaryurn:org.iodp:exp:186urnlargerWorkCitationcampaignurn:org.iodp:exp:86urnlargerWorkCitationcampaignurn:org.iodp:exp:86:site:579urnlargerWorkCitationstudyurn:org.iodp:exp:86urnlargerWorkCitationcampaignurn:org.iodp:exp:86:site:580urnlargerWorkCitationstudyurn:org.iodp:exp:86urnlargerWorkCitationcampaignurn:org.iodp:exp:186:site:1150urnlargerWorkCitationstudyurn:org.iodp:exp:186urnlargerWorkCitationcampaignurn:org.iodp:exp:186:site:1151urnlargerWorkCitationstudyurn:org.iodp:exp:186urnlargerWorkCitationcampaignEnglishgeoscientificInformation143.2000143.200038.450039.1100Available only on CD-ROM in PDF format and on the Web in PDF or HTMLapplication/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://www-odp.tamu.edu/publications/186_SR/VOLUME/CHAPTERS/110.PDFdownload
