Abstract The effects on the temperature microstructure of terrestrial heat flow and heat flow anomalies at the ocean floor are discussed on the basis of a simple heat diffusion model. The effects on the temperature microstructure of layering of the thermal properties of the ocean are investigated. This is done both mathematically and graphically. The anomaly forms that are studied in detail are the point source, the infinite line source, the distributed half plane
source, and the strip source. Except for the point source, consideration is given only to the steady-state solutions of the diffusion equation. The two layer diffusivity model that is used assumes a contrast of the thermal diffusivities and is intended to be a simple approximation of what has been experimentally observed. The graphical study has a two-fold purpose: First, the graphs provide a quick means of comparing experimental data with the models that have been developed. Second, they provide a basis for predicting the possibility of experimentally observing the different forms of anomalies that are discussed. Finally, a study is made of the effect of various levels of precision of temperature measurement on the observability of heat flow anomaly patterns. The source strengths necessary for observation are discussed together with the range of anomaly strengths that are experimentally observed.
