OCE-9504198 The investigators will examine physical and theoretical relationships among physical processes, sediment transport and morphology across shoreface, which might lead to understanding of storm-dominated vs. swell-dominated shorefaces. This will involve detailed examination of time-series of morphology and concentration of inner shelf sediments. Deployment of acoustic instruments that are better capable of quantifying cross-shore transport are proposed for both storm and swell-dominated shorefaces. Models will be modified to account for cross-shorface sediment and fluid motion which recognize the simultaneous contribution of both wave and wind forcing.

OCE-9504198 研究人员将研究物理过程，沉积物输运和整个滨面形态之间的物理和理论关系，这可能会导致对风暴为主与膨胀为主的滨面的理解。 这将涉及详细检查内陆架沉积物的形态和浓度的时间序列。 部署声学仪器，更好地量化跨海岸运输的能力，提出了风暴和涌浪为主的滨面。 模型将被修改，以考虑到跨shorface沉积物和流体运动，其中认识到波浪和风强迫的同时贡献。
