Acoustic-trawl surveys provide estimates of biological distributions that can inform stock assessments and other ecosystem-based management strategies. These measurements can also derive other biometrics (e.g. average body length) and behavioral …
Water column sonar data collected by echosounders are essential for marine ecosystem research, allowing the detection, classifi cation, and quantification of fish and zooplankton from many different ocean observing platforms. However, broad usage of …
In this presentation, I will discuss fundamental concepts of using active acoustic techniques as a remote sensing tool to observe mid-trophic level fish and zooplankton in the ocean. These observations complement passive acoustic measurements that …
