• Is there enough zooplankton to feed forage fish populations off Peru? An acoustic (positive) answer (2011, background): “However, most of the studies that provided biomass acoustic estimates have been performed in the Antarctic area, where acoustics is used as a standard tool to estimate krill biomass (Watkins and Brierley, 2002).”
• Distribution and population dynamics of Euphausia superba: summary of recent findings (2005, methodology): “2003) using the two-frequency technique for species identification (Watkins and Brierley 2002).”
• Variations in the biomass of Antarctic krill (Euphausia superba) around the South Shetland Islands, 1996–2006 (2008, methodology): “Both exploit the pairwise DSv at three frequencies (Demer et al., 1999; Watkins and Brierley, 2002; Hewitt et al., 2003) to discriminate krill from other co-habitant scatterers.”
• Interannual variability in Antarctic krill (Euphausia superba) density at South Georgia, Southern Ocean: 1997–2013 (2014, unknown): “Net-validated krill targets have been shown to have a DSv of between 2 and 12 dB using 120 and 38 kHz (Madureira et al., 1993: Watkins and Brierley, 2002).”
