“…For visualization of coral reefs, however, useful images are limited to those environments in shallow, clear water less than 10-20 m depth (FINKBEINER, STEVEN-SON, and SEAMAN, 2001;FINKL, 2005;HOPLEY, 1996;PURK-IS, 2005). Other remote sensing tools must be implemented to map turbid and deep reefs (ANDERSON, GREGORY, and COLLINS, 2002;FINKL, BENEDET, and ANDREWS, 2005;GAL-LOWAY, 2001). Among these devices are high-resolution bathymetry and acoustic ground discrimination (HAMILTON, MULHEARN, and POECKERT, 1999;.…”
