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
abundance of Antarctic krill continuously between 14 October 2002 and 29 December 2005. A distinct seasonal ... pattern in krill abundance was detected that recurred consistently over all 3 years. Krill densities ... explained 71% of the observed week-week variation. Mooring estimates of krill abundance were ... not statistically different (P>0.05) from estimates derived from standard ship-based krill surveys in adjacent ...
