The sonar has an oil-filled plastic \"boot\" providing protection for its acoustic transducer which operates with a narrow conical beam pattern.Typically the sonar is mounted vertically, looking down at the sea-bed, and captures a sequence of profiles of the sea-bed over a pre-programmed sector and range. The sonar gathers a single swath of data in the horizontal plane and then rotates the transducer through a pre-programmed angle around the vertical axis and repeats the process until a circular area underneath the sonar has been scanned in a sequence of radial spokes."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL0046" ; skos:note "accepted"@en ; skos:prefLabel "Marine Electronics Sand Ripple Profiling Sonar"@en ; skos:related .
