Narrative

Scotia sailed from Aberdeen at 1000 on 10 August and commenced trawling on the stations east of Aberdeen. Three survey stations were completed during the day and the vessel then carried out a further 3 hauls in relation to objective 5 (collecting samples of 0-group cod and haddock). A further 10 survey hauls were completed off the east coast of Scotland using ground gear "A" before the vessel worked towards the Moray Firth region where trawling continued with ground gear "B". Scotia worked in a northerly direction, covering stations in the Moray Firth and Orkney areas before calling into Scalloway during the morning of 15 August to allow a member of the scientific staff to return to Aberdeen. Two further stations were sampled off the west of Shetland before poor weather conditions intervened on the morning of 16 August. With continuing westerly gales forecast, Scotia moved to the more sheltered waters off the east of Shetland where work resumed. With a gradual improvement in weather conditions Scotia worked towards the Norwegian Sector and proceeded to cover the stations in the northeastern part of the survey area before moving into Danish waters on 21 August. Scotia called into Esjberg for a mid cruise break on the morning of 22 August, sailing again the following morning. With confirmation being received from Denmark and Germany about the coverage on the southern part of the survey area, a decision was taken to drop 5 of the original stations in order to create time for additional sampling in the Shetland region.

Scotia completed the stations in the southern part of the survey area then worked northwards, completing the rest of the original survey area on 29 August. The vessel then moved from the Fair Isle region to the north of Shetland where work on additional stations commenced on the morning of 30 August. Damage to the trawl gear on grounds west of Shetland restricted sampling to 4 valid hauls for the day. Work continued the next morning in the Papa Bank area but further severe damage to the trawl gear resulted in the cancellation of the remaining two planned stations. Scotia then proceeded towards Aberdeen, docking in the late evening with unloading taking place on 1 September as scheduled.
