Estimating target strength and physical characteristics of gas-bearing mesopelagic fish from wideband in situ echoes using a viscous-elastic scattering model
Khodabandeloo, Babak; Agersted, Mette Dalgaard; Klevjer, Thor Aleksander; Macaulay, Gavin John; Melle, Webjørn Raunsgård (Peer reviewed; Journal article, 2021)Wideband (38 and 50–260 kHz) target strength of organisms were measured in situ using a towed platform in mesopelagic (200–1000 m depth) layers. Organisms with a gas-inclusion are strong scatterers of sound and acoustically ... -
Remote acoustic sizing of tethered fish using broadband acoustics
Kubilius, Rokas; Bergès, Benoît; Macaulay, Gavin John (Peer reviewed; Journal article, 2023)Remote fish sizing is desirable in fisheries (e.g., pre-catch) and research (e.g., platforms without biological sampling capacity) applications. In those contexts, the high spatial resolution of pulse compressed broadband ...
