      Coordination of the survey was initiated in the meeting of the Working Group on International Pelagic Surveys (WGIPS) and continued by correspondence until the start of the survey. During the survey, updates on vessel positions and trawl activities were collated by the survey coordinator and distributed to the participants twice daily. The survey design used and described in ICES (2015) allowed for a flexible setup of transects and good coverage of the spawning aggregations. Overall weather conditions were good during the survey with a total of 3 days weather down time recorded. Transects undertaken by all vessels were consistent in spatial coverage and timing, delivering full coverage of the respective distribution areas within 23 days.

      Coordination of the survey was initiated in the meeting of the Working Group on International Pelagic Surveys (WGIPS) and continued by correspondence until the start of the survey. During the survey effort was refined and adjusted by the survey coordinator (Norway) using real time observations. The survey design was based on methods described in ICES Survey design Manual (2015). Overall weather conditions were mixed with periods of poor and good weather. All vessels experienced some downtime due to poor weather conditions. The entire survey was completed within 20 days, below the 21 day target threshold.
