    <p>Density of postlarval krill [ind. m<sup>−2</sup>] at the open surface and under ice (0–2) m in summer (2007/2008), autumn (2004) and winter (2006). Mean values significantly different from each other (ANOVA <i>p</i><0.05) were printed in bold. ice = under-ice SUIT hauls; ow = open water SUIT hauls; <i>n</i> = number of samples.</p

    <p>Generalized Additive Models of the density of postlarval krill. Effect of additive smoothing functions of (<b>A</b>) proportional ice coverage during SUIT hauls, and (<b>B</b>) mixed layer depth in summer (2007/2008), (<b>C</b>) salinity in the 0–200 m depth layer in autumn (2004), and (<b>D</b>) temperature in the mixed layer in winter (2006) on the fitted density of postlarval krill. Dashed lines show 95% confidence intervals of smoothers.</p

    <p>Day/night comparisons of the surface layer density of (<b>A</b>) postlarval krill at three locations in summer (2007/2008), (<b>B</b>) postlarval krill, and (<b>C</b>) furcilia larvae at two locations in winter (2006). Scaling of y-axis differs. Denotations above bars are location codes. d = daytime, night = night-time; ice = under-ice, ow = open water SUIT hauls.</p
