Dive time and diver training were not obstacles to video acquisition for landscape mosaics, which in this case took only 25 min per mosaic by a diver who had only one practice acquisition. Processing each mosaic took about 1 h of analyst time and 24 h of computer time. The ease of data acquisition, ability to use off-the-shelf hardware (i.e., a video camera and possibly lights), and potential suite of indicators (e.g., benthic cover, coral sizes, disease prevalence, and bleaching) that can be obtained from the images suggest that landscape mosaics could be applied widely for surveys of mesophotic coral ecosystems.
Strategic Environmental Defense Research Program (SI-1333 to R.P.R.), Caribbean Fishery Management Council (T.B.S.), and Spanish Ministry of Education and Science (N.G.) provided funding. J. Blondeau, J. Calnan, E. Kadison, and R. Nemeth assisted in the field.
