The aim of my project is to compare underwater visual survey methods on their estimates of environmental variables. Specifically, I conducted underwater visual census and stereo-video surveys on the same coral reef sites in a marine protected area in Cayos Cochinos, Honduras. I am currently analyzing the results to see how UVC and SVS differ in estimates of species richness, diversity, abundance, and biomass. Based on my results, I will assess the suitability of each method in measuring these variables, as well as some advantages and disadvantages of each method, (although more research will be needed to provide a complete assessment). The results of this research could greatly change the current trends in data collection, and provide better information for management of marine resources.
