We establish, for smooth enough initial data, the global well-posedness (existence, uniqueness and continuous dependence on initial data) of solutions, for an inviscid three-dimensional slow limiting ocean dynamics model. This model was derived as a strong rotation limit of the rotating and stratified Boussinesq equations with periodic boundary conditions. To establish our results, we utilize the tools developed for investigating the two-dimensional incompressible Euler equations and linear transport equations. Using a weaker formulation of the model, we also show the global existence and uniqueness of solutions, for less regular initial data.
