A review and update of krill biomass trends in the South Shetland Islands, Antarctica, using the simplified stochastic wave born approximation
(Euphausia superba) between 1997 and present. Over the last five years proportional recruitment as been ... compared. Biomass estimates from the two algorithms are highly correlated (>0.95), with identical CV’s ... . Use of acoustic windows based on the range of krill size increases variability in biomass estimates ... and CV’s. These data suggest that future development focus on better propagating error through levels ...
