As a global marine environmental consultancy supporting energy and coastal infrastructure projects, CSA operates scientific echosounder systems—including Kongsberg Discovery EK-series split-beam instruments—to collect calibrated water-column backscatter data during offshore surveys. These systems provide high-resolution measurements throughout the water column, enabling detection and characterization of fish aggregations, scattering layers, suspended particulates, and gas seeps. While advanced acoustic instrumentation is increasingly deployed across offshore industries, rigorous and transparent post-processing remains essential to generating defensible scientific results. Echoview software is widely used by federal agencies such as the National Oceanic and Atmospheric Administration (NOAA) and by universities conducting fisheries and oceanographic research.…
