Abstract
The properties of the seabed affect the amplitude and character of an echosounder or sidescan sonar return. Conversely, it is possible to use the statistical variation of these returns to segment the seabed into various regions – according to their acoustic characteristics. In this report we consider the returns from the SIMRAD echosounder (two different frequencies) on the CFAV Quest as well as the returns from the Klein 5500 sidescan sonar collected during the DRDC Atlantic/SACLANTCEN trial, MAPLE. Acoustic features are defined which allow us to segment the seabed into different acoustic regions for two different sites, Herring Cove, Halifax Harbour and St. Margaret’s Bay. As well, some selected underwater photographs taken by SACLANTCEN and selected sidescan sonar images are presented from the 2 sites.
