Characterization of sound scattering layers in the Bay of Biscay using broadband acoustics, nets and video acoustics and biological data

Sound scattering layers (SSLs) are observed over a broad range of spatio-temporal scales and geographical areas. SSLs represent a large biomass, likely involved in the biological carbon pump and the structure of marine trophic webs. Yet, the taxonomic composition remains largely unknown for many SSLs.
