Cruise Inventory Information

Long name FRV Scotia (748S) cruise 0312S
Short name 0312S
Objectives and Narrative Objectives

1. Demersal trawling survey of the grounds off the north and west of Scotland in ICES Subarea VIa.
2. To obtain temperature and salinity data from the surface and seabed at each trawling station.
3. Collect additional biological data in connection with the EU Data Collection Framework (DCF).
4. Opportunistic sampling using the Gulf 7 to determine densities of mackerel eggs within the area covered by the trawl survey.

Narrative

Scotia sailed from Aberdeen at 0800 on 19 February. A familiarisation haul was completed successfully on a clear tow at the Buchan Deeps east of Peterhead with the fishing gear, Scanmar and bottom contact sensors performing well. On completion of the shakedown trawl, Scotia then made passage north towards the first station west of Orkney. By 0700 on 20 February, a full gale was blowing and Scotia was forced to dodge until mid afternoon when a lull in the weather allowed the first station to be completed successfully. Scotia then sailed west overnight towards the shelf edge arriving on station for first thing on the morning of 21 February. Four stations were completed successfully in the area north of the Windsock before another gale curtailed fishing operations once more. More settled conditions arrived on 22 February and Scotia was able to complete five hauls around the Windsock and Otter bank area, with the fifth station carried out during the hours of darkness.

The following morning Scotia completed her first station which was just North of Strathy Point before heading into the Minch with a severe westerly gale expected imminently. By midday the wind was gusting 65 knots, however, Scotia was able to complete a further three trawls in the Minch before heading south overnight towards the next trawl station NW of Skye. The presence of static gear buoys around us meant that only a 20 minute trawl was possible although thankfully upon recovery of the trawl there was no evidence of creels or leader lines. Scotia then continued on and into the South Minch where another four stations were completed, the last of which was a replacement haul as the original position (SW of Tiree) was unfishable.

An overnight steam SW brought Scotia to the stations NW off Donegal and over the next two days, with weather conditions easing considerably Scotia successfully completed the nine fishing stations in this SW corner of the survey area and deployed the Gulf 7 sampler on five stations at locations straddling the 200 m contour. On Monday 27 February, Scotia headed southeast completing four stations north of the Donegal coast (hauls 98-101).

Scotia made passage for Belfast and the mid-cruise break. Scotia left Belfast at 0800 on 29 February and headed across the Irish Sea to complete the stations in the Clyde, successfully completing two stations within daylight hours.

During 1 March, Scotia completed the last station in the Clyde just east of the Mull of Kintyre before proceeding west, completing another three stations just to the south of Islay and Jura.

The second core station at Red Bay being abandoned due to there being no suitable ground for trawling and so the nearest replacement location was sourced 15nm south of Jura. Over the next three days and nights, Scotia, with fresh westerly winds, worked at Stanton Banks and then NW tackling the deeper stations to the West of St Kilda completing 13 fishing stations. The vessel also deployed the Gulf sampler at night on seven occasions during this period on set stations straddling the 200 m contour. Another five stations were completed on 5 March. The last of these taking place during darkness because of impending bad weather that was expected for the following day. Three Gulf deployments were also completed in this area NW of the Butt of Lewis before Scotia headed east for shelter in the Minch.
