             abstract = "Human activity and natural climate trends constitute a major 
                         threat to coral reefs worldwide. Models predict a significant 
                         reduction in reef spatial extension together with a decline in 
                         biodiversity in the relatively near future. In this context, 
                         monitoring programs to detect changes in reef ecosystems are 
                         essential. In recent years, coral reef mapping using remote 
                         sensing data has benefited from instruments with better resolution 
                         and computational advances in storage and processing capabilities. 
                         However, the water column represents an additional complexity when 
                         extracting information from submerged substrates by remote sensing 
                         that demands a correction of its effect. In this article, the 
                         basic concepts of bottom substrate remote sensing and water column 
                         interference are presented. A compendium of methodologies 
                         developed to reduce water column effects in coral ecosystems 
                         studied by remote sensing that include their salient features, 
                         advantages and drawbacks is provided. Finally, algorithms to 
                         retrieve the bottom reflectance are applied to simulated data and 
                         actual remote sensing imagery and their performance is compared. 
                         The available methods are not able to completely eliminate the 
                         water column effect, but they can minimize its influence. Choosing 
                         the best method depends on the marine environment, available input 
                         data and desired outcome or scientific application.",
