This project is an investigation of the Lagrangian displacement of water masses in the deep equatorial Atlantic Ocean using both analytical and numerical approaches. Two numerical models are used: a reduced gravity shallow water model, and the GDFL ocean general circulation model. The main scientific goals are (1) identification of dominant mechanisms for generating wave transients and how can these transients affect Lagrangian displacement of water masses and, (2) analysis of effects of bottom topography and shoreline geometry on the Lagrangian equatorial transport.

该项目利用分析和数值方法对赤道大西洋深海水团的拉格朗日位移进行研究。 使用两个数值模型：减重力浅水模型和 GDFL 海洋环流模型。 主要科学目标是（1）确定产生波浪瞬变的主要机制以及这些瞬变如何影响水团的拉格朗日位移；（2）分析底部地形和海岸线几何形状对拉格朗日赤道输送的影响。
