Geochemical Ocean Sections Program Atlantic data have been used to examine the effects of the nonlinear P-V-T properties contributing precision and new information to the calculation of changes in the potential energy (ET). Where both temperature and salinity (T-S) gradients are sufficiently large and have opposing effects on the density (namely at stations with Central Water), a relationship between ET and sigma-theta exists, and nonlinear effects are evident. In addition, in Central Water masses, an adiabatic interchange followed by mixing can be accompanied by a decrease in ET, i. e. energy can be converted from potential to another form. The structure of ET has been related to the T-S finestructure, and then circumstantially to processes that have been associated with layered structure; e. g. double-diffusive processes (salt-fingering) and cabbeling. To illustrate how much ET is available for release by an adiabatic exchange and subsequent mixing of layer interfaces, layers were constructed in the pycnocline of an idealized subtropical region.
