Narrative

Staff joined the Scotia at 06.00hrs and the vessel sailed by 07.00h on 3 December. Fire and boat drill were completed by 08.00h while the vessel proceeded to deep water for test deployments of the CTD system, the plankton winch and associated crane. Following these, a test deployment of the ARIES system fitted with a Seabird 911 system was completed. Several faults with both systems were identified and worked on while the vessel made a passage to the end of the extended Jonsis line. Staff were unable to repair the faults with the Seabird CTD system, which meant that the Seabird sealogger system had to be modified to be fitted to the ARIES frame.

Work started on the eastern most end of the Jonsis line at 23.55h on 3 December and continued steadily until 08.00h when the wind had reached 50knts, coupled with a heavy swell, meant that Scotia was forced to dodge for 12 hours. When the weather allowed Scotia worked steadily westwards along the Jonsis line stations completing the line by 03.45h on 5 December.

Scotia set away in poor weather conditions to the southern most end of the Fair Isle -Munken line and commenced work at 10.29h on 5 December. Scotia completed ten stations along the Fim line and occupied Fim8 by midnight on 6 December in freshening winds. By 07.00h on Sunday, the master decided that given the conditions and the forecast that Scotia would make for shelter at Sydero in the Faeroe Islands.

The weather had moderated sufficiently by 05.30h on 8 December to allow Scotia to complete Fim11 and an ARIES tow at Fim 10 before making a passage north to the western end of the Nol line and starting the first station at 16.36h. Steady progress was made along the line and Nol 18 was reached by midnight in intermittent snow showers. However, by 06.30h on 9 December after completing Nol 7 Scotia was forced to dodge in strong winds and a heavy swell. Conditions had improved by 07.30h on 10 December to allow Nol 6 to be completed safely.

Good weather meant that steady progress was made along the Nol line and it was completed on 11 December at 18.45h. On completion of the last Nol station Scotia was forced to seek shelter in the lee of Unst in deteriorating weather and sea conditions. Scotia dodged in the lee of the North end of Unst for seventy two hours during which time the wind increased dramatically at times up to storm force 12. On 14 December, Scotia tried to go round Flugga to start a series of stations to the east of Shetland, however, a very large swell and strong winds forced the vessel to turn back. Scotia then made a passage down the west side of Shetland in an attempt to get to a line of stations on the west side of Shetland. The first of these was reached at 19.00h and a CTD was deployed in very poor conditions. However, as Scotia was making for the next station on the line, in deteriorating weather with increasing winds, and poor forecast , the decision was taken by the master and senior fishing mate to abandon the line of stations and for Scotia to make for Aberdeen at 20.30h on 16 December.
