Abstract:

This work describes the development of a high resolution echo sounder for use with the RP FLIP. The instrument has a source level of 227 dBmicro Pa, a 3 dB beam width of 1 deg and a receiver sensitivity of - 176 dBMicro Pa rpoviding operating capabilities as a bottom sounder for water depths to 2000 m. The results of its operation at sea along with observations of acoustic returns from multiple thin scattering layers to depth of over 400 m. are included. Graphic examples under various operating conditions are presented as well as reflection coefficients measured from bottom returns and acoustic scattering target strengths.
