Resumen
A maximum threshold setting in the noise removal part of the Echoview template used for acoustic krill biomass estimation can remove significant amounts of krill backscatter. A revised threshold setting is proposed and applied to the 2019 International Synoptic Krill survey in Area 48, resulting in a 16% increase in the biomass estimate.
