A passive remote sensing method of relative depth (a variable proportional to water depth) of shallow water is proposed. It is similar in the prediction formula with the well-known regressive method by Lyzenga et al.(2006), but is unique in that it doesn't require any auxiliary input data other than single multispectral image: the coefficients of the formula is estimated by utilizing pixels of near-zero depth extracted from image, without relying on in-situ measurements of water depth or other optical properties. The accuracies (correlation coefficient between estimated and measured depth) of the both methods are tested using a QuickBird image of a coral reef area. As a surprising result, the accuracy of the new method is found to be comparable and sometimes even superior to that of Lyzenga et al.'s method.
