Biomass estimates of Antarctic krill around the South Shetland Islands based on surveys conducted by a Chinese fishing vessel from 2013 to 2019

Time series of annual biomass estimates of Antarctic krill around the South Shetland Islands during the period of 2013 to 2019 is provided to aid the discussion on biomass estimation in Subarea 48.1. The estimates were based on data described in the working document ASAM-2019-04r1, which presented the time series of krill density estimates resulting from the annual acoustic surveys conducted by the Chinese krill fishing vessel FU RONG HAI from 2013 to 2019. A wrong data column (biomass density instead of acoustic density) for the year 2019 in Table 3 of ASAM-2019-04r1 was also corrected for future reference.
