The surfaces of bicontinuous disordered microemulsion structures or L₃ phases can be described as level cuts of random Gaussian fields with a given spectrum. We consider here the difference between the entropy of these states and the known entropy of the generating random field. In another context, this difference is equal to the decrease in the Shannon information content resulting from the process of sampling and digitising of continuous stochastic signals.
