Narrative

This survey was conducted using a random-stratified design with trawl locations being distributed within ten predefined sampling strata. The intention is for trawls to be undertaken on suitable ground as near to the specified sampling position as is practicable and where possible within a radius of five nautical miles of that position. If no suitable ground can be located within five nautical miles then the nearest alternative trawl station should be used. Hauls will be of 30 minutes duration and generally fishing operations will take place during the hours of daylight where possible.

On this survey, Scotia sailed from Aberdeen at 0900 on Tuesday 13 November and proceeded south to deploy hydrographic equipment and associated marker buoy in Stonehaven bay. This was carried out successfully and with no difficulties, after which J Dunn and M Geldart were put ashore in Stonehaven by ships rescue craft.

On leaving Stonehaven bay Scotia made a northerly course for the first trawl station to the west of Orkney. While en-route, the opportunity was taken to deploy and check the operation of the trawl gear; in particular to measure the gear dimensions under strain.

Fishing commenced the next day at 0700, at a position to the west of Orkney. The short term weather forecast was reasonable for this time of year and advantage of this was taken to progress westward for the next three days.

Scotia had to arrange for a member of scientific staff to be put ashore in Ullapool to seek medical attention. This saw Scotia working in the North Minch on Friday 16 November before docking in Ullapool at 1300. During the port call, an Echomaster engineer was called to effect repairs to a motion compensated balance.

Scotia departed Ullapool at 1730 and progressed towards stations to the north of Lewis. Careful monitoring of forecasts suggested that we were to encounter uncomfortable weather conditions in the days to come but nothing that should prevent us from continuing our operations.

Scotia continued to work west and then southwards down the shelf edge, in rough weather conditions to the west of the Stanton Banks. Overnight passage was then made to Barra to disembark one of the ships crew on the morning of Thursday 22 November.

Scotia worked in a northerly direction though the South Minch and then made passage for Ullapool for the scheduled half landing.

Scotia docked in Ullapool at 2215 on Thursday 22 November. During the half landing the repaired basket weighing balance was returned to the vessel. A staff exchange was undertaken whilst in port.

Scotia departed from Ullapool at 0700 on the morning of 24 November, heading south to a station located to the east of Harris.

Scotia continued operations south through the Stanton banks area and then south westwards down the west coast of Ireland. Surveying continued along the north coast of Ireland and then into the Clyde sea area on 30 November. Designated core stations of the survey design were completed on 30 November. Scotia undertook seven additional survey stations up the shelf edge to the west of the Hebrides, finding us positioned at 'Clash Deeps' on the morning of 3 December, where sc
