Narrative

Scotia sailed from Aberdeen at 0930 on 26 January and started work on the station east of Aberdeen, with the GOV trawl being deployed, rigged with groundgear "B". With trawling restricted to daylight hours it was only possible to complete one further station before embarking on Methot Net sampling for herring larvae. With this work being done during the hours of darkness, the vessel completed 8 hauls before arriving at the next trawling location for daylight. The GOV trawl was deployed with groundgear "A" for the first station of the day but the loss of small fish from the inner cod-end resulted in the haul having to be repeated. This was resolved by adopting a different method of tying the cod-end and both crew watches were briefed in this procedure. With favourable weather conditions forecast for several days, Scotia proceeded in an easterly direction in order to complete the outer stations of the survey area. Work continued uninterrupted on the eastern and southern part of the survey area until the evening of 3 February, when Scotia worked west throughout the night to arrive at stations south west of Shetland for daylight on 4 February. Six stations were completed to the west and north of Shetland before Scotia called in to Lerwick for the mid cruise break on 6 February. The vessel sailed again the following morning, resuming work on the stations east of Shetland. Severe weather prevented deployment of the Methot Net in the early hours of 8 February and Scotia moved in towards the east coast of Shetland in order to seek shelter. With the winds forecast to decrease, the vessel resumed work the following morning at the station east of Sumburgh Head. The vessel completed the stations in the central part of the survey area then moved in towards the inshore stations of Orkney and Moray Firth on 13 February. The survey area was completed on the afternoon of 14 February. Additional work was carried out off the north east coast of Scotland in order to obtain biological data in relation to the EU Data Collection Regulations. Scotia docked in Aberdeen on the evening of 15 February and unloading commenced at 0800 on the morning of 16 February.
