      1     Introduction
      1.1     Opening of the meeting
      1.2     Adoption of the agenda
      1.3     Modification/adoption of meeting agenda
      2     Review proof of concept: stage 2

      Review of data collected during a range of vessel activities, speeds and weather conditions to assess more fully the quality and utility of acoustic data from commercial fishing vessels.

      3     Protocols for data collection and analysis, with emphasis on Simrad echosounders (EK60, ES60/70)
      3.1     Data collection
      3.1.1     Validation of instrument performance

      Internal testing and external reference target, with focus on the role of seabed as reference target for individual and inter-ship calibration, taking into account of inputs from fishing vessel masters.

      3.1.2     Instructions on instrument setup
      3.1.3     Work on protocols for data collection with other echosounder/sonars where applicable
      3.2     Data screening and analysis
      3.2.1     Noise removal algorithms (standardised procedures)
      3.2.2     Data analysis (software-specific)
      3.2.3     Uncertainty evaluation methods, including data quality/data loss
      4     Analysis of data collected during fishing operations
      4.1     Spatial and statistical treatment
      4.2     Potential input into WG-EMM on the use of fishing vessel-based acoustic data in the 2015/16 multinational effort as well as in FBM in general
      5     Other issues and future work
      6     Recommendations to the Scientific Committee

      Including recommendations to WG-EMM for work related to FBM.

      7     Adoption of report
      8     Close of meeting
