Intra-annual variability in the abundance of Antarctic krill (Euphausia superba) at South Georgia, 2002–2005: within-year variation provides a new framework for interpreting previous ‘annual’ krill density estimates

Krill densities ... in winter were predominantly low (mean = 18.7 g m-2 SD 24.3) but rose substantially by summer in each year ... . within-year) could have led to the perceived between-year variation from previous summer surveys ... survey estimates with the observed pattern of within-year variability showed that some of the alleged ...
