[Coral-List] Rugosity of artifical reefs

[nicole caesar]

Hello all,
The MS thesis project that I conducted with Dr. John Brock of the USGS and Dr. Pamela Hallock-Muller of USF St. Pete also demonstrated a relationship between natural reef rugosity and ecological vitality: An evaluation of the Along Track Reef Imaging System (ATRIS) for efficient reef monitoring and rapid groundtruthing of EAARL Lidar,
Best,N. Caesar.

Sorry, about the confusion. Better to call it rugosity. We are not talking about surface roughness. In the topographic world we use the tern 'roughness' which is the log of rugosity. 
 
Let me try again:
 
 I wonder whether it would be worthwhile our comparing the rugosity of artificial reefs with that for natural reefs. If rugosity is a good measure of topographic complexity and this is related to ecology and fish habitat, we could see some important science. We have good bathymetry for some natural reefs and would just need bathy/topo data for artificial reefs.

I believe the roughness over natural reefs has been pursued by Stanford folks:  graduate students C MacDonald, R Lowe, M Reidenbach. Profs Koseff and Monismith.
