ObjectivesObjectives

1. To complete an internationally coordinated demersal trawling survey in the North Sea in ICES area IV.
2. To obtain temperature and salinity data from the surface and seabed at each trawling station.
3. Opportunistic acoustic surveying of oil and gas installations using EK60 during downtime to assess their importance as refugia for icthyofauna.

Narrative

Scotia sailed from Aberdeen at 0715 on 22 July. The first haul that also doubled as a familiarisation haul was completed successfully on a clear tow 12 nm east of Girdleness with the fishing gear, Scanmar and bottom contact sensors performing well. Scotia then headed 20 nm SW to Stonehaven bay in order to redeploy a guard buoy for a mooring that had come adrift. This was completed by 1630 after which the hydrographic personnel aboard were transferred ashore to Stonehaven and replaced by the two remaining members of the scientific complement yet to join the vessel. Scotia was underway by 1930 and was able to complete a second station just east of Montrose, again without incident. Overnight Scotia then made her way into the Firth of Forth and by first light on 23 July was on station 20 nm North of Eyemouth in rectangle 41E7. Unfortunately, the net was badly torn and after completing a further three stations to the east of this, Scotia returned to a backup position within 41E7 the following morning where the net was deployed successfully. During the next three days and with calm conditions Scotia completed the southern component of the survey.

In addition to the trawling, three oil/gas installations (Breag, Munro and Tyne) were successfully surveyed using the downtime during the night. With the calm conditions continuing Scotia proceeded east completing the stations in the southeast of the survey area. Another two oil installations (Gyda and Tor) were successfully surveyed whilst Scotia was en route to the next fishing station during the night.

In the main the fishing operations were completed without incident, however, on the afternoon of 29 July, whilst undertaking haul 350 in 41F5 the net stuck fast on the bottom and despite numerous attempts to release it the gear was lost with only the doors being retrieved. Efforts were made to retrieve the gear user a creeper but this was to no avail and a new net was rigged. The station was repeated successfully on the same tow but beyond the location of the fastener. Because of the time lost rectangle 41F4 was dropped from the survey plan in order for Scotia to maximise the overnight steam west to commence next morning at rectangle 42F2. A further eight stations were completed before docking in Aberdeen at 2300 on 31 August for the half landing. In addition, the Buchan platform was successfully surveyed on the night of 30 July prior to completing the first station the following morning.

Scotia sailed at 1000 on the morning of 2 August and headed straight for the Moray Firth successfully completing three stations along the south coast as well as a survey of the Beatrice Platform on the same night. From there Scotia proceeded north and east before completing the stations around Orkney and then Shetland. Once again these were generally completed without incident although Scotia sustained another foul haul in rectangle 48E7. Despite significant damage to the net, it was repaired in good time allowing an additional haul to be completed that evening and the following day an alternative tow for rectangle 48E7 was sourced and completed successfully.

On 7 August, Scotia proceeded eastwards from Shetland completing stations on the north eastern boundary of the survey area before heading south to complete the remaining survey area. During this period, Scotia was able to successfully survey three oil platforms (Oseberg, MCP01 (disused) and the submerged Piper Alpha foundations). The last two fishing stat
