A 100-m-long sediment core (ZK1) from the modern Huanghe Delta (Bohai Sea) were analyzed to docu- ment the stratigraphy and sea-level changes since the Late Quaternary. Accelerator mass spectrometry ~4C dating and analyses of benthic foraminifera, ostracods, and sedimentary characteristics were analyzed for Core ZK1. Seven depo sitional units ( DU1 to DU7 in descending order) were identified and interpreted as follows : DU 7 corresponds to ter- restrial facies in MIS 4 ; DU 6 and DU 4, to alternating terrestrial and marine facies in MIS 3 ; DU 3, to terrestrial fa cies in MIS 2 ; DU 2, to Holocene marine facies ; and DU 1, to the modern Huanghe Delta sediments deposited since 1855. By correlation with other welt-studied cores in the nearby area, three transgressive layers of Core ZKI were in agreement with Bohai and Xianxian transgressions in MIS3, and Huanghua transgressions in MIS1. These sedimentary facies of Core ZK1 reflect several sea-level fluctuations since MIS4, which played a key role in controlling the sedi mentary environments in the study area.
