Scotia sailed from Aberdeen at 1015 hours on 25 January. After safety drills and familiarisation protocols, the vessel deployed both trawls (A and B gear) to ascertain adjuster chain length and to ensure the operation of the Scanmar net monitoring system. The MIK net was also deployed for familiarisation purposes and to undertake flow meters calibration runs. The medium term weather forecast suggested that we were to encounter moderate conditions for the next 48 hours. As such, Scotia worked south from Aberdeen, then east and north, covering the offshore stations which required both ground-gear "A" and "B" to be deployed. Weather conditions deteriorated from 28 January onwards up to the time of the half landing on 4 February. MIK sampling was undertaken at a rate of two tows per statistical rectangle where trawling events took place. This pattern of operation continued up until 4 February when Scotia docked in Aberdeen for her scheduled half landing. Scotia departed from Aberdeen on the morning of 5 February and resumed the survey in the Moray Firth. Scotia then worked up the west side of Orkney, through Fair Isle waters and up the west side of the Shetland Isles. The survey continued across the top of Shetland and then in a southerly direction down the east side. This continued until the morning of 13 February, when Scotia was forced to dodge in the Fair Isle channel due to poor weather conditions. The vessel sustained minor damage to forward port side of her bow, including a smashed port hole, which saw slight ingress of water. The weather improved rapidly from 0300 hours on the morning of 14 February, allowing one MIK tow to be completed before recommencing fishing operations at 0715 hours. The standard scheduled sampling stations were completed by 1500 hours, when Scotia made way south to complete two further MIK stations. Once all scientific operations were completed, Scotia then made way for Aberdeen, docking alongside at 0530 hours on 15 February.
Scientific staff disembarked on the morning of Friday 15 February after unloading all samples and equipment not required for the following survey 0313S.
