High-resolution foraminiferal isotopic records obtained from cores fromthe East China Sea and Japan Sea reveal a pattern of contrasting hydrographies for the last 6000 years.The first core,retrieved from the uppercontinental slope of the East China Sea,was analyzed for δ^(18)O and δ^(13)Cin both Neogloboquadrina dutertrei(planktonic)and Uvigerina spp.(benthic)foraminifera and,hence,provides a record of paleoceanographic changethrough time.The relatively reduced amplitude of the planktonic δ^(18)O signal relative to the benthic samples suggests some modification resulting fromchanges in the prevailing Kuroshio Current.A progressive depletion in boththe δ^(18)O and δ^(13)C records of N.dutertrei over the last 2000 years suggestsa warmer,more humid climate around the East China Sea.Isotopic recordsof the second core collected from the Japan Sea show a comparable temporalresolution to those from the East China Sea,but they exhibit larger amplitudes presumably due to the more restricted hydrographic setting and greatersensitivity to environmental changes in that area.In addition to the temperature differences revealed by oxygen isotopes,the N.dutertrei δ^(13)C recordsfor these two cores also provide clues as to the evolution of the KuroshioCurrent during the late Holocene.
