Abstract :
A specific analysis of reflected acoustic signals enables real-time bottom classification during hydrographic operations using modern signal processing technology. Supplementary seabed data can be collected and portrayed for considerations such as ground fish habitat evaluation, shellfish distributions, oil spillage residue mapping, and pre-dredging analysis. An instrument which performs this task is described and evaluated
