OCE 9617639 Boyer The project will investigate the dynamics of flow over submarine canyons using a combined physical and numerical modeling approach. The models will be designed to study the interaction between barotropic, oscillatory currents in a stratified fluid and a submarine canyon interrupting an otherwise smooth shelf-slope topography. The nature of time- dependent and mean fields, flow separation at the canyon edge, and mass transport in the vicinity of the canyon will be investigated. The idealized approach will be extended to the modeling of specific canyons for which field data are available.

OCE 9617639 Boyer 该项目将采用物理和数值模拟相结合的方法研究海底峡谷上方的水流动力学。这些模型将被设计用来研究分层流体中正压振荡流与海底峡谷之间的相互作用，而海底峡谷则中断了原本平滑的陆棚斜坡地形。将研究随时间变化的场和平均场的性质、峡谷边缘的气流分离和峡谷附近的质量输运。理想化的方法将被扩展到特定的峡谷的实地数据的建模。
