Since the early 20th century echosounders have developed from simple systems used for depth sounding to sophisticated multi-frequency systems that are routinely used in global fish stock assessments. While stock assessments are essential to ensure our sustainable use of the ocean, echosounder data have the potential to provide considerable insight into ecosystem function beyond biomass estimations.
Given the combined pressures of exploitation and climate change on marine ecosystems, it has never been more pressing to understand how ecological communities will respond to rapid environmental changes. Novel active acoustic techniques, when augmented with additional emerging technology, provide opportunities to assess environmental and ecosystem functioning simultaneously, across a variety of disciplines.
This session will showcase the use of echosounders to provide insights into global marine ecosystems beyond standard stock assessment, and will explore the practical application of emerging technologies and complementary techniques to improve ecological understanding.
Three main topics will be discussed during the session:
