This is a project to define the shallow and deep structure of the lower reaches of the relict Yellow River where it emptied on the outer shelf and the structure of the presumed delta and fan in the Okinawa Trough. The study will use seismic data previously collected by the principal investigator and his collaborators to trace former channels of the Yellow River and define sediment depocenters. %%% The Yellow River system is unique amongst the large rivers of the world in that during low stands of sea level at least some of its sediment apparently empties into an enclosed basin. It is even more interesting that this basin is a tectonically active back arc basin. Dr. Milliman has done pioneering work on this classic field area and this project is a continuation of that important effort.

该项目旨在确定流经外陆架的残黄河下游的浅层和深层结构以及冲绳海槽中假定的三角洲和扇的结构。 该研究将使用主要研究者及其合作者先前收集的地震数据来追踪黄河以前的河道并确定沉积物沉积中心。 %%% 黄河水系在世界大河中是独一无二的，因为在海平面较低时，至少其部分沉积物明显流入封闭盆地。 更有趣的是，这个盆地是一个构造活动的弧后盆地。米利曼博士在这个经典领域做出了开创性的工作，这个项目是这一重要努力的延续。
