    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
