      1     Opening of the meeting
      2.1     Dedicated surveys

      The Working Group will consider the content and quality assurance required to deliver krill biomass estimates from dedicated surveys to CCAMLR for use in management, including survey design, data collection protocols, data analysis protocols, quality checking methods and reporting needed.

      3     Krill biomass estimates
      3.1.1     Subarea biomass estimates
      3.1.2     Local-scale biomass estimates within subareas relevant to the area of operation of the krill fishery
      3.2     Area 58

      The Working Group will review survey results for biomass estimates from the East Antarctic surveys.

      4     Acoustic observations of krill to inform spatial and temporal dynamics of krill
      4.1     Survey on nominated transects by fishing vessels

      The Working Group will consider the design of acoustic data collection on CCAMLR nominated transects and reporting needed from fishing vessels, including where and when acoustic data are collected, as well as ancillary data required for processing acoustic data (calibration data, krill length frequency data, environmental data, etc.).

      4.2     Acoustic observation from various platforms

      The Working Group will consider design and analysis methods to examine temporal variability of krill distribution by observations from various sources (e.g. gliders, moorings, and acoustic data collected during routine fishing activities).

      5.1     Chair’s report of the SC-Symposium
