The development of the knowledge and understanding of the thermodynami
cs of melting ice in sea water is reviewed with special attention to r
ecent contributions to the literature on the subject. The contribution
s are dealt with in a chronological order, which also happens to coinc
ide largely with the development of relevant models from the simplest
molecular conductive/diffusive to multilayer turbulent models applicab
le to the melting of drifting ice in the planetary boundary layer.
