Abstract: Use of high resolution (0.1m) side-scan sonar for generating detailed benthic maps (4 m 2 mapping unit) in coral reef environments was investigated by collecting imagery over 60 km 2 of the Puerto Rico insular shelf, from shoreline to shelfedge. Visual interpretation of acoustic imagery resulted in 21 different habitat types classified within broad categories of unconsolidated sediment (7), consolidated bottom (6), and vegetated areas (8). Detailed maps showed the amount, size, and spatial distribution of habi… Show more

“…Several papers have discussed the cost-effectiveness of remote sensing, but these focussed mainly on the image and the processing cost, and not on the integration of field and image data in relation to calibration or validation [1,75,134]. Two publications described how the cost and accuracy of a coral reef map were influenced by varying either the number of data points [123], or the image type or size of the mapped area [11].…”

“…Diver-based monitoring is extremely limited in space and time, while satellite-based approaches have not resolved the benthic surface at the resolution of coral colonies [8]. Current high-resolution, reef-scale approaches for 3D benthic mapping primarily utilize SONAR (sound navigation and ranging) and LIDAR (light detection and ranging) technologies [9,10]. Ship-based SONAR has proven valuable for generating detailed bathymetry and reef rugosity information at high spatial resolution.…”

“…To better understand the distribution of coral structures in Bonaire, both the classification data as well as the calculated rugosity values must be interpreted. A high rugosity value is often indicative of the presence of coral structures (Prada et al, 2008), in fact 11.8% of all data points had a rugosity ratio of 1.3 or greater and were found within the inferred hard coral acoustic class (Figure 6). In Figure 6, the classifications assigned to each data point are shown along with the percentage of the seabed coverage that each class accounted for.…”
