1 Introduction
Documents
1.1 Opening of meeting
Documents
1.2 Meeting terms of reference and adoption of the agenda
Documents
2 Provide advice that will assist in quantifying uncertainties in krill B0 estimates
Documents
2.2 Collate a set of net-validated acoustic data and evaluate whether current acoustic target identification methods are biased
Documents
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.
Documents
2.1 Review recent research results including developments in target strength modelling and observations on krill orientation and material properties
Documents
3 Document the current agreed protocols for krill B0 assessment
Documents
4 Discuss the use of ancillary acoustic data (e.g. from finfish surveys, exploratory fisheries data and commercial fisheries echo sounders)
Documents
4.2 Document protocols for analysing, processing, and interpreting ancillary acoustic data (e.g., data collected during exploratory fisheries)
Documents
4.3 Determine whether such data can provide krill biomass estimates from areas that are not regularly surveyed
Documents
4.4 Discuss future needs for acoustic instrumentation in the Antarctic
Documents
4.1 Review recent research results involving collection of ancillary acoustic data

Documents
5.3 Determine whether data can provide krill biomass estimates from areas that are not regularly surveyed
Documents
6 Evaluate developments in target strength modelling and other new observations on Antarctic fish species
Documents
