30 years of advances in active bioacoustics: A personal perspective

Abstract

The area of active bioacoustics involves the use of sound to study distributions of fish and zooplankton in aquatic environments. There have been significant advances in this area over the past 30 years, covering many categories, spanning technology and modeling. These advances, as witnessed throughout my career, are reviewed. Issues with past and current approaches are discussed as well as projections into the future.
