Measurement of the thermal field developed around a heated penetrometer tip is proposed as a method for determining the in situ flow and transport characteristics of uneonsolidated saturated porous media. The purely diffusive thermal field developed around a static penetrometer is modified in the presence of penetration induced advective fluxes. The modification is conditioned by the advective thermal diffusivity and the elastic compressibility of the porous medium, enabling formation diffusivity to be evaluated where compressibility may be determined independently from the pressure transient record.
