Determination of Dynamic Ocean Topography Using the Minimum Energy State

ABSTRACT
Geostrophic balance represents the minimum energy state in a linear system with conservation of potential vorticity. On the base of that, a minimum energy state (MES) method is proposed to determine dynamic topography (畏) and in turn the absolute geostrophic velocity from hydrographic data through finding 畏 to minimize a functional, 
. Numerical approach leads to a set of well-posed linear algebraic equations of 畏 at grid points. Feasibility and advantage of the MES method are illustrated using the three-dimensional (T, S) data of the NOAA National Centers for Environmental Information (NCEI) World Ocean Atlas 2013 version 2 for the North Atlantic Ocean (100oW-6oW, 7oN-72oN) on 1o 1o grids.
