説明

<jats:p>Late Quaternary sediments of the Japan Sea are characterized by centimeter‐ to meter‐scale alternations of dark and light layers which are synchronous basinwide. High‐resolution analyses of the sediments from Ocean Drilling Program site 797 reveal that deposition of the meter‐scale alternations reflect variations in paleoceanographic conditions which were closely associated with glacio‐eustatic sea level changes through the modulation of the volume and character of the influx to the sea through the Tsushima Strait. The centimeter‐ to decimeter‐scale alternations reflect millennial‐scale variations which are possibly associated with Dansgaard‐Oeschger (D‐O) cycles, with each dark layer appearing to correspond to an interstadial. This variability is attributed to the development of a humid climate in central to eastern Asia and the consequent increase in discharge from the Huanghe and Changjiang Rivers during interstadials. This caused expansion of the East China Sea coastal water (ECSCW), which penetrated more strongly into the Japan Sea. The increased influence of the lower‐salinity, nutrient‐enriched ECSCW reduced deep water ventilation and enhanced the surface productivity, leading to the development of anoxic bottom waters and deposition of the dark layers. Thus the centimeter‐ to decimeter‐scale alternations of the dark and light layers record wet and dry cycles in central to eastern Asia possibly associated with D‐O cycles.</jats:p>
