Coastal Upwelling Circulation on a Wide Shelf: An Observational Study

9521102 Garvine在这个项目中，PI将对新泽西外的中大西洋湾这一广阔大陆架上的沿海上升流环流进行观测研究。 目标是：1. 解析质量平衡，至于是二维还是三维; 2. 确定主要的地下跨陆架输送通道和沿陆架压力梯度的动力学重要性; 3. 确定上升流锋的形成条件，并探讨其在物质通量和热通量中的作用; 确定最大上升流区的位置; 5. 找出热收支中的主要项。 将使用各种系泊和船上仪器、卫星跟踪漂流器以及温度和颜色卫星图像。

9521102 Garvine In this project, the PIs will conduct an observational study of coastal upwelling circulation on a wide continental shelf -- the mid-Atlantic Bight off New Jersey. The objectives are: 1. To resolve the mass balance, as to whether it is two or three- dimensional; 2. To determine the primary subsurface across-shelf transport pathway and the dynamical importance of along-shelf pressure gradient; 3. To determine criteria for formation of an upwelling front, and find its role in the mass and heat fluxes; 4. To determine where the zone of maxiumum upwelling occurs; and, 5. To find the principal terms in the heat budget. A variety of moored and ship-board instruments, and satellite-tracked drifters, as well as satellite imagery of temperature and color will be used.
