Acoustic properties of Salpa thompsoni.
Wiebe, Peter H.; Chu, Dezhang; Kaartvedt, Stein; Hundt, Anna (Hölter); Melle, Webjørn; Ona, Egil; Batta-Lona, Paola (ICES CM documents;2009 / I:01, Working paper, 2009)Salps are common members of the world oceans planktonic community (Madin, et.al., 2006). In the southern ocean, both krill (Euphausia superba) and salps (Salpa thompsoni) can occur in dense aggregations (Loeb et al, 2009, ... -

Further analysis of target strength measurements of Antarctic krill at 38 and 120 kHz: Comparison with deformed cylinder model and inference of orientation distribution
Chu, Dezhang; Foote, Kenneth G.; Stanton, Timothy K. (Journal article; Peer reviewed, 1993)Data collected during the krill target strength experiment [J. Acoust. Soc. Am. 87, 16–24 (1990)] are examined in the light of a recent zooplankton scattering model where the elongated animals are modeled as deformed finite ... -

Foote, Kenneth G.; Chu, Dezhang; Baldwin, Kenneth C.; Mayer, Larry A.; McLeod, Andrew; Hufnagle, Lawrence C. jr.; Jech, J. Michael; Michaels, William (Others, 2003) -
Protocols for calibrating multibeam sonar
Foote, Kenneth G.; Chu, Dezhang; Hammar, Terence R.; Baldwin, Kenneth C.; Mayer, Larry A.; Hufnagle, Lawrence C. jr.; Jech, J. Michael (Journal article; Peer reviewed, 2005)Development of protocols for calibrating multibeam sonar by means of the standard-target method is documented. Particular systems used in the development work included three that provide the water-column signals, namely ... -
Quantitative processing of broadband data as implemented in a scientific split-beam echosounder
Andersen, Lars Nonboe; Chu, Dezhang; Handegard, Nils Olav; Heimvoll, Harald; Korneliussen, Rolf; Macaulay, Gavin; Ona, Egil; Patel, Ruben; Pedersen, Geir (Peer reviewed; Journal article, 2023)The use of quantitative broadband echosounders for biological studies and surveys can offer considerable advantages over narrowband echosounders. These include improved spectral-based target identification and significantly ...
