Poseidon Ocean General Circulation Model (OGCM) is designed with generalized horizontal and vertical coordinates. While the formalism ensures conservation of mass, momentum, heat, salt and other tracers under any grid choice, the specific selection of the grid definition provides additional benefits. In the vertical, we adopt a three-tiered layering system comprised of a bulk turbulent mixed layer, a deep ocean treated with isopycnal layering, and a buffer zone between the two in which a sigma-like layering is employed. All of the three regions can be sub-divided into many (or zero) layers.
