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
pattern in krill abundance was detected that recurred consistently over all 3 years. Krill densities in ... winter were predominantly low (mean = 18.7 g m-2 SD 24.3) but rose substantially by summer in each year ... statistically different (P>0.05) from estimates derived from standard ship-based krill surveys in adjacent ... periods suggesting that the mooring point estimates had relevance in a wider spatial context (ship surveys ...
