Data, which can be obtained from any vessel geared with multi-frequency echosounders, provide relevant information to study the impact of physical processes on biogeochemical and ecological processes marine life and extracting valid information about the pelagic habitat and its spatial structure. All these data are to develop actual Ecosystem-based Fisheries Management in the current context of climate change. As an example we propose a synthesis of a scientific program developed in the Humboldt Current system off Peru which is the most productive in terms of fish and encompasses a shallow and intense oxygen minimum zone. specialized PEROU PACIFIQUE 040 036 3 Piscataway IEEE 2013 RIO Acoustics 2013, Rio de Janeiro (BRA), 2013/07/24-26 https://www.documentation.ird.fr/hor/fdi:010064376 10.1109/RIOAcoustics.2013.6683995 978-1-4799-0362-7 [F B010064376] https://www.documentation.ird.fr/hor/fdi:010064376 https://www.documentation.ird.fr/intranet/publi/depot/2015-04-27/010064376.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2015-04-27 2023-02-22 fdi:010064376 fre
