The Fluid Mechanics of Submarine Fan Morphogenesis: An Experimental Study

约翰·索萨德计划继续他的实验室实验，研究浊流如何构造海底扇。 这项工作是在一个充满水的盆地中进行的，面积为5米乘5米，深1米，有一个假底，在假底上引入了淤泥大小的玻璃珠沉积物悬浮液，浓度为几个体积百分比，作为浊流。 30到40次这样的流动事件形成了一个大型海底扇，内部分层明显。 随着存款的积累，在扇体上形成了移动通道的模式。 下一阶段的工作将利用更先进的剖面测量设备，根据浊流的流动特征，更详细地描述存款的地层结构。

John SouthardEAR 9909261PI plans to continue his laboratory experiments on how turbidity currents construct submarine fans. The work is being done in a water-filled basin, 5 m by 5 m in area and 1 m deep, with a false floor onto which a suspension of silt-size glass bead sediment, at concentrations of a few percent by volume, is introduced as turbidity currents. Thirty to forty such flow events build a large submarine fan, with distinct internal stratification. As the deposit builds up, patterns of shifting channels develop on the fan. The next phase of the work will make use of more sophisticated profiling equipment to characterize in more detail the stratigraphic architecture of the deposit as a function of the flow characteristics of the turbidity currents.
