1. Biomass results from the International Synoptic Krill Survey in Area 48, 2019

   Abstract:  Results from the International Synoptic Krill Survey in Area 48, 2019, are presented. This survey covered both the strata occupied during the CCAMLR 2000 acoustic survey and the strata that comprise the regular AMLR survey. Acoustic transects (10534 n.mi), oceanographic measurements (253

7. Methodological aspects of the International Synoptic Krill Survey in Area 48, 2019

   Abstract:  The effect of differences in the methodology used for the CCAMLR 2000 krill acoustic survey and the 2019 synoptic survey were considered. These were 1) the effect of acoustic surveying at night, 2) differing trawl selectivity between the vessels that participated in the survey, and 3)
