A visualization-based post-processing system for analysis of acoustic data

Abstract

A commercial data-visualization package, AVS, and database are used as the basis for a powerful and highly flexible acoustic data analysis system. The system is easy to use and can be modified by the user to incorporate novel visualization and analysis capabilities as required. Multi-frequency ping-by-ping or integrated data from a variety of echo-sounders may be viewed and manipulated within the system. Here, we describe the main features of the system and illustrate how it may be used to mark, transform, analyse, and compare dual-frequency acoustic data.
