| dc.description.abstract | 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 coordinator based on real time observations. The survey design applied followed methods described in ICES Survey design Manual (2015) and allowed for a flexible transect design and comprehensive coverage of the spawning aggregations. Overall weather conditions were mixed with periods of poor and good weather. All vessels, with the exception of Kings Bay experienced some downtime due to conditions with the Faroes experiencing the most prolonged period of bad weather at the end of the survey period. The entire survey was undertaken within 20 days and below the 21 day target threshold. The bulk of the survey was temporally consistent with the exception of one transect in the southern Rockall Trough. | en_GB |

International Blue Whiting Spawning Stock Survey (IBWSS) Spring 2013Coordination 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. Norway did not participate in the survey this year. The survey design used and described in ICES (2012) allowed for a flexible setup of transects and good coverage of the spawning aggregations. Due to acceptable - good weather conditions throughout the survey period, the survey resulted in a high quality coverage of the stock. Transects of all vessels were consistent in spatial coverage and timing, delivering full coverage of the respective distribution areas within 19 days.
