The thermobaric nonlinearity in the equation of state for seawater density-namely, the dependence of thermal expansibility on pressure-coupled with spatial variation of the oceanic temperature-salinity (θ-s) relation generates a nonlinear behavior in the buoyant force that can counter the linear dis...
