Across-shelf Mixing of a Buoyancy-driven Coastal Current: An Observational Study

项目建议在特拉华海岸流地区进行实地实验，目的是调查沿海流的浮力水与大陆架水的跨大陆架混合。三个主要目标是：(1)确定产生跨陆架混合的主要物理过程；(2)通过对潮下流和盐度场的观测，构建沿海流的盐通量平衡；(3)获得沿海流源区浮力通量（或盐通量）与河流流量和沿岸风应力的预期主要强迫因子之间的定量和统计显著关系。

The PI proposes to undertake field experiments in the region of the Delaware Coastal Current with the goal of investigating the across- shelf mixing of buoyant water from the coastal current into shelf water. The three major objectives are: (1) to identify the principal physical processes that produce across-shelf mixing, (2) to construct the balance of salt flux for the coastal current from observations of the subtidal current and salinity field, and (3) to obtain a quantitative and statistical significant relationship between the buoyancy flux (or salt flux) from the coastal current source region and the expected principal forcing agents of river discharge and alongshore wind stress.
