The aim of this second part of the article is to study with several concrete cases the absolute definition of the seawater entropy described in Part I. Observed vertical profiles and polar transects, as well as analysed surface data, show that very different temperature and salinity values can organise to create new isentropic regions that can only be revealed by the absolute formulation of the entropy of seawater (Arctic Ocean; Bay of Bengal; Mediterranean, Black and Caspian Seas). Existing hypotheses to explain these results include the possible impact of turbulent processes that must be applied to the entropies of the atmosphere and oceans.
