Classification trees for species identification of fish-school echotraces (2009, background): “These trawling operations took place after completing a 15 min (2.5 nautical miles or 4.6 km) elementary distance sampling unit (EDSU; Simmonds and MacLennan, 2005), and involved temporarily interrupting the survey track to trawl on the observed echotraces.”
Vertical segregation of age-0 and age-1+ polar cod (Boreogadus saida) over the annual cycle in the Canadian Beaufort Sea (2016, methodology): “A linear regression of mean TS on log10 of the mean SL of polar cod sampled in the corresponding hauls was then calculated to transform the backscatter signal into fish size (Foote 1987; Simmonds and MacLennan 2005).”
Variability in natural behaviour, and observed reactions to an ROV, by mid-slope fish species (2006, unknown): “However we note that in recent times species specific target strength data has become available to improve on the acoustic identification and behaviour of certain deep-sea fish (Simmonds & MacLennan 2005).”
Mesopelagic fish biomass in the southern California current ecosystem (2015, methodology): “Forward modeling of fishes Estimation of fish abundance using the technique of echo integration requires the mean backscattering cross section (σbs) and area scattering (NASC; (Simmonds and MacLennan, 2005)).”
Hypoxia affects spatial distributions and overlap of pelagic fish, zooplankton, and phytoplankton in Lake Erie (2009, unknown): “We used Sv as a relative measure of fish biomass density (Simmonds and MacLennan, 2005), wherein higher levels of Sv correspond to higher levels of total fish biomass density (Taylor et al.”
Northern Cod Comeback (2015, methodology): “Standard methods of acoustic integration of 38 kHz signals were employed throughout (Simmonds and MacLennan 2005) as in previous reports (e.”
Acoustic biomass estimation of mesopelagic fish: backscattering from individuals, populations, and communities (2015, background): “sv is integrated by depth to produce the area backscattering coefficient, sa (m 2 m(22)), and abundance 1⁄4 sa/sbs (ind. m(22); Simmonds and MacLennan, 2005).”
Prey density and distribution drive the three‐dimensional foraging strategies of the largest filter feeder (2015, methodology): “…(Lawson et al. 2006) to calculate a krill target strength estimate of 75 0 dB (Watkins & Brierley 2002) [Correction added after online publication date 10 June 2015: 5 0 dB changed to 75 0 dB] which we used to convert acoustic backscatter to estimates of krill density (Simmonds & MacLennan 2005).”
Developing an acoustic survey of euphausiids to understand trophic interactions in the Bering Sea ecosystem (2012, methodology): “Seminal observations by Balls (1948) and Sund (1935) in the first half of the 20th century showed that ship-based acoustic echosounders could detect fish schools, and since that time there has been substantial development of acoustic equipment and methods to estimate the abundance of both fishes (Si”
Evolution and current state of the technology of echo-sounder buoys used by Spanish tropical tuna purse seiners in the Atlantic, Indian and Pacific Oceans (2014, background): “…backscatter ransformation into biomass is having appropriate target strength alues per species (target strength is a measure of the reflection oefficient of a sonar target) (Simmonds and MacLennan, 2005). urrently, the target strengths for most of the species associted with DFADs remain unclear.”
