Experiments on Convection and Dense Plume Dynamics on a Sloping Bottom

0080069/SM这个项目包括研究在陆架上形成致密水，然后在陆架水受到负表面浮力通量影响时向深处下降的方式。其目的是模拟以威德尔海为主要动机的大陆架上的致密水形成。方法是在旋转槽中进行实验室实验，采用简化的搁板斜面几何形状。这些实验与以前的实验不同，因为使用了分布的表面浮力通量，通过一种新的方法试图量化从下坡重力流中排出的粘性流体，以及在斜坡地形上包含峡谷和山脊。

0080069/SmethieThis project consists of a study of the way in which dense water is formed on a shelf and then descends to depth when the shelf-water is subject to a negative surface buoyancy flux. The intent is to model dense water formation on continental shelves with the Weddell Sea quoted as the main motivation. The approach is to perform laboratory experiments in a rotating tank with a simplified shelf-slope geometry. The experiments are distinguished from earlier experiments by the use of a distributed surface buoyancy flux, by a novel approach to trying to quantify the viscous flow draining fluid from the down-slope gravity currents, and by the inclusion of canyons and ridges on the slope topography.
