In this study, the spatial character of benthic communities is investigated in an Arabian Gulf shallow subtidal carbonate ramp setting, using IKONOS satellite imagery. The patchy distribution of three assemblages of live and dead corals on extensive (but also fragmented) hardground pavements was investigated using a variety of spatial statistics. It was found that the spatial expression of the benthic groups display characteristics that approximate to power-law distributions over several orders of magnitude to an extent that suggests fractal behaviour. Pronounced anisotropy was observed between the spatial patterns in the near-shore and off-shore region which is attributed to different mechanisms …
