      1     Introduction
      1.1     Opening of meeting
      1.2     Meeting terms of reference and adoption of the agenda
      2     Provide advice that will assist in quantifying uncertainties in krill B0 estimates
      2.2     Collate a set of net-validated acoustic data and evaluate whether current acoustic target identification methods are biased
      2.3     Provide direction towards developing a probability density function for the estimate of B0 based on the current understanding of uncertainties in various parameter values.
      2.1     Review recent research results including developments in target strength modelling and observations on krill orientation and material properties
      3     Document the current agreed protocols for krill B0 assessment
      4     Discuss the use of ancillary acoustic data (e.g. from finfish surveys, exploratory fisheries data and commercial fisheries echo sounders)
      4.2     Document protocols for analysing, processing, and interpreting ancillary acoustic data (e.g., data collected during exploratory fisheries)
      4.3     Determine whether such data can provide krill biomass estimates from areas that are not regularly surveyed
      4.4     Discuss future needs for acoustic instrumentation in the Antarctic
      4.1     Review recent research results involving collection of ancillary acoustic data
      5     Evaluate results from IPY surveys in 2008
      5.2     Presentation of new results from IPY surveys
      5.3     Determine whether data can provide krill biomass estimates from areas that are not regularly surveyed
      6     Evaluate developments in target strength modelling and other new observations on Antarctic fish species
      6.1     Presentation of new results
      7     Attempt to resolve difficulties identified with the swept-area estimation of icefish abundance
      7.1     Discuss appropriate application of the adjustment factor for trawl headline height used in surveys for C. gunnari
      8     Suggestions for timing/venue of next meeting
      9     Recommendations to Scientific Committee
      10     Adoption of Report
      11     Close of Meeting
      5.1     Review acoustic data and related metadata submitted to CCAMLR
