Narrative

Scientific staff joined F.R.V. Alba na Mara in Fraserburgh at 1100 on 7 January 2009. A short delay was necessary to allow time for some minor adjustments to be made to the video equipment before the vessel sailed at 1230. Once in deep water to the north of Fraserburgh, the initial task of stretching and improving the lay of the umbilical on the TV winch was carried out by deploying the sledge and most of the cable then recovering the equipment under tension. The poor sea conditions experienced hindered the initial 2 deployments however, the third attempt proved successful, as did the following 2 stations, which were completed before heading back to port, arriving there at 1930. Three more stations were carried out in the same vicinity the following day, before steaming 40 miles north of Fraserburgh and surveying 2 sites before the sea conditions proved too difficult to work in. The vessel arrived in Arberdour Bay at 2000 where it anchored for the night.

Working in a semi-circular pattern on 9 January, 11 stations were surveyed before heading back to Fraserburgh in anticipation of gale force conditions over night. Due to the weather, the vessel stayed in port during the following 2 days. Before sailing on the morning of
12 January, Martin Burns left the vessel and returned to the Lab, having completed his work aboard. The vessel headed west to find areas with more shel
