Storm-Driven Circulation and 'Event Bed' Genesis on the Northern Gulf of Mexico Continental Shelf

建立路易斯安那-得克萨斯大陆架事件层沉积动态地层学模型的模拟研究。敏感性测试将有助于定义一套物理上可实现的解决方案。主要目的是验证粗粒“事件”层是短暂风暴的结果这一假设。模拟将试图在风暴频率和大陆架可容纳空间的框架内回答以下问题：形成这些海床所需的地转流的强度、沙子的来源、区域范围和间隔特征以及事件海床的垂直顺序。

A modelling study to construct a dynamic stratigraphic model of event bed deposition on the Louisiana-Texas continental shelf. Sensitivity tests will help define a set of physically realizable solutions. The main objective is to test the hypothesis that coarse-grained "event" beds are the result ofshort-lived storms. The modelling will attempt to answer questions about the strength of geostrophic flow necessary to form these beds, the source for the sand, regional extent and interval characteristics and the vertical sequence of the event beds in the framework of the frequency of storms and availability of accommodation space on the shelf.
