• Biogeographic Atlas of the Southern Ocean (2014, background): “In summer, when trophic conditions are insufficient, female E. superba rely on oosorption (Cuzin-Roudy & Amsler 1991), a common strategy for crustaceans to retrieve yolk components from developed oocytes to fuel the obligatory energetic expenses of their behaviour (Hamner & Hamner 2000).”
• Variability and predictability of Antarctic krill swarm structure (2009, background): “However, the absolute numbers of krill in large swarms creates an internal microenvironment of waste products, reduced O2, parasites, disease and lack of food that is ultimately detrimental (Hamner and Hamner, 2000).”
• Using a high-powered strobe light to increase the catch of Antarctic krill (2004, result): “In comparisons of the abundance of krill in a given region based on acoustical techniques, marine mammal and sea bird foraging requirements, visual observations by divers, and net tows, the net estimates are nearly always significantly lower than the other estimates (Sameoto 1981; Everson and Bone 1”
• Protozoans as a food source for Antarctic krill, Euphausia superba: Complementary insights from stomach content, fatty acids, and stable isotopes (2006, background): “They could be related to different origins of krill if schools disperse and form rapidly (e.g., Hamner and Hamner 2000).”
• KRILLBASE: a circumpolar database of Antarctic krill and salp numerical densities, 1926–2016 (2016, background): “…retention Differences in net geometry, towing speed and trajectory will further affect catches, as will light levels and swarm packing density (Hamner and Hamner, 2000; Everson and Bone, 1986; Krag et al., 2014 For example, catchability decreases as light levels increase, meaning that there…”
• Prey density and distribution drive the three‐dimensional foraging strategies of the largest filter feeder (2015, background): “…krill density can also be affected through environ- mental factors such as the physical forcing of ocean currents and interactions with seafloor topography, and these phenomena can manifest seasonally, tidally or in response to other geophysical forces (Hamner 1984; Ham- ner & Hamner 2000).”
• Distribution, Biomass and Demography of Antarctic Krill, Euphausia superba (2016, background): “They also may also show a diel vertical migration which may be strong or absent (Hamner and Hamner 2000; Siegel 2005), and may even use the bottom as a habitat (Kawaguchi et al.”
• Krill, Currents, and Sea Ice: Euphausia superba and Its Changing Environment (2006, background): “Despite findings that krill are active schooling animals (Hamner and Hamner 2000) and evidence suggesting active migrations (Siegel 1988), a predominant view among Southern Ocean ecologists is that krill are planktonic organisms largely at the mercy of their physical environment (Hofmann and Murphy…”
• Oceanic circumpolar habitats of Antarctic krill (2008, background): “As well as size and lifespan (Quetin et al. 1994, Quetin & Ross 2003), these attributes include cruising speeds of ~20 cm s–1 (Kils 1982), schooling (Daly & Macaulay 1991, Hamner & Hamner 2000) and horizontal migrations (Kanda et al. 1982, Siegel 1988, Sprong & Schalk 1992, Lascara et al. 1999).”
• Distribution and population dynamics of Euphausia superba: summary of recent findings (2005, background): “This may be an observation of krill’s general natural behaviour (Hamner 1984; Hamner and Hamner 2000).”
• Quantification of marine snow fragmentation by swimming euphausiids (2004, background): “The nearest neighbor distance for schooling E. superba is ;30 mm (Hamner and Hamner 2000), and these euphausiids likely have effective radii of at least 15 mm, since they are twofold to threefold larger than E. pacifica.”
