An 8-year cycle in krill biomass density inferred from acoustic surveys conducted in the vicinity of the South Shetland Islands during the austral summers of 1991/1992 through 2001/2002
years and indications that ice cover in the winter of 2002 is seasonally early and extensive. Author(s ... , comparisons with the proportion of juvenile krill in simultaneous net samples suggest that the changes in ... biomass density are consistent with apparent changes in reproductive success. A truncated Fourier series ... fit to the biomass density time series is dominated by an 8-year cycle and predicts an increase in ...

Our inshore results were consistent with those from offshore bottom trawl sampling in ... (3) a high abundance of N. coriiceps. Reasons for lack of recovery in G. gibberifrons remain obscure ... with trends reported in seabirds that feed on juveniles of these notothenioids: decrease in the areas ...
