    Резюме

    In June 2010 the CCAMLR ASAM working group examined the acoustic methodology applied to the CCAMLR 2000 synoptic survey data to generate a quality checked krill biomass for area 48 following the acoustic protocol identified in ASAM 2009. The total biomass of krill in the Scotia Sea was estimated from acoustic and net data collected during the international multi-ship krill biomass in the Scotia Sea in 2000 to be 60.3 million metric tonnes. This report aims to document the parameters utilised during the assessment and include additional information of krill density by strata and transect published for the original methodology, but omitted from the ASAM2010 report (SC-CAMLR-XXIX, Annex 5).
