This proposed study will the vertical accretion of tidal flats off western South Korea, which may provide an excellent analog for ancient mudflat sequences in the PreCambrian and lower Paleozoic. The field program, involving both current meter and coring operations, will focus on the following objectives: 1) test the hypothesis that long-term tidal channel stability is controlled by tidal-cycle and season time-scale transport processes in the bottom boundary layer; 2) document the net flux of sediment between the tidal channel systems and adjacent mudflats; 3) determine the relationship between physical processes and the resultant lithology and structure preserved in the sediment column.

本研究对韩国西部潮滩的垂直增生进行了研究，为前寒武纪和下古生代的古泥滩序列提供了很好的模拟。现场项目包括测流仪和取心作业，将集中于以下目标：1)验证长期潮汐通道稳定性受底层潮汐周期和季节时间尺度输送过程控制的假设；2)记录潮道系统与邻近泥滩之间的净泥沙通量；3)确定物理过程与沉积柱中保存的岩性和结构之间的关系。
