KONGSBERG GEOACOUSTICS Side Scan Sonars - 4

Applications Cymodocea Nodosa (Wikipedia) Environmental Surveys Habitat mapping in the Mediterranean using Sonar 2094 Digital. The data show different growth types of Posidonia Oceanica and Cymodocea Nodosa on a sandy seafloor. The seagrass species play a crucial role in the Mediterranean ecosystem. Monitoring its extent and growth pattern is an important part in assessing marine habitats. Posidonia Oceanica: (Wikipedia) Environmental Surveys Texture mapping using Sonar 2094 Digital, left 410 kHz, right 114 kHz, acquired simultaneously. 4

KONGSBERG GEOACOUSTICS Side Scan Sonars - 7

Side Scan Technology Kongsberg Mesotech Side Scan sonars provide acoustic images of the seabed. The acoustic signal is transmitted and received by a pair of transducers, which are deployed in the towfish. The beam patterns show narrow kHz: 0.3°) and wide vertical directiv- beams intercept the seafloor in thin stripes. The backscatter values from the short acoustic signal are recorded as time series across the stripes, revealing bathymétrie and textural differences of the seafloor. The image is built up with consecutive transmission pings along the travel path of the sonar. The best image is...
