We have worked on issues such as you describe using remote sensing in the
Arabian Gulf. The work considers the prevalence of different facies units
in the reef landscape, as well as their complexity and spatial arrangement.
To a degree, it appears that these properties of the reefscape are
predictable through the existence of scaling-laws.
