[Seavox] New L05 term request - profiling sonars

[Paba, Violetta]

Hello,

Please see a recent request for adding 'profiling sonars' to L05: https://github.com/nvs-vocabs/L05/issues/12

profiling sonars
High-frequency (>1 MHz), possibly multiple frequency, active sonar systems that provide high-speed cross-sectional profile of the target area. They are deployed on a surface survey vessel pointing the transducer down towards the target or mounted on an ROV/AUV/UUV. Applications of profiling sonars include cross-sectional profiling in pipeline and trench survey, bottom profiles, and surveying of underwater cave systems or manmade structures like road and rail bridge foundations. Examples of this type of system are Tritech Super SeaKing DFP Profiler and Imagenex 881A Profiling Sonar Head.

Please let me know by Friday the 12th of February whether you'd have any comments or reservations about the creation of this new term.

FYI, see below two of the most similar existing terms:

152
sidescan sonars
Instruments with directional acoustic transmitters and receivers fitted to an underwater platform that emit fan-shaped pulses down toward the seafloor across a wide angle perpendicular to the path of the platform through the water.

378
sediment profile imagers
Devices that provide in-situ still or video images of a section including bottom water, the undisturbed sediment-water interface and the upper sediment layers.

Thanks and kind regards,

Violetta
