| Session Description | East Asian marginal seas such as the Bering Sea, Okhotsk Sea, Japan/East Sea, and the East and South China Seas are located under significant influence of the East Asian summer and winter monsoon. Heavy precipitation in summer gives an impact on the fresh water budget of sea surface water mass, while severe cooling in winter promotes dust events and sea ice formation. Temporal variations of all these aspects were well recorded in the sediments of the East Asian marginal seas, which have been utilized as many kinds of proxies to reconstruct the past summer and winter monsoon variability through time. Since the onset and variability of paleo-monsoon have been associated with tectonic evolution of Indo-Eurasian continents and these marginal seas, multi-disciplinary approach is necessary for full-understanding of the tectonics-climate-oceanographic relationship and their impacts on the marginal seas as well as the resulted sediment records. Here, we call for presentations related to paleoclimatological and paleoceanographic reconstructions using soils and sediments in the East Asian margin, which include sedimentological and provenance studies, paleontological and geochemical proxies, and modeling efforts in centennial to tectonic time-scales. |
