Data provided in this data set were collected around the Flower Garden Banks National Marine Sanctuary (FGBNMS) as part of NOAA National Centers for Coastal Ocean Science (NCCOS)-led benthic data collection missions for the ongoing National Coral Reef Monitoring Program (NCRMP), consisting of two survey types: the Line Point-Intercept (LPI) method and the Coral Demographic method. The LPI method provides a measure of percent cover of biotic and abiotic components of the benthos in a stratified random sampling design in hardbottom and coral reef habitats. The coral demographics protocol provide more detailed and species-specific insight (‘signal magnitude’) for coral populations than is provided by percent cover.
