Summary

Beginning with the equation of state of seawater, the chapter proceeds to apply the first and second laws of thermodynamics to seawater. These, in turn, lead to the equilibrium and well-mixed states that provide references for the mixed state of the ocean. Molecular flux laws also follow from the thermodynamic discussion, and then the turbulent buoyancy flux and its effect on potential energy is considered. After exploring TS diagrams, expressions for water mass conversion are discussed, including thermobaricity, cabbeling, and dianeutral velocity.
