All scientific staff joined FRV Alba na Mara in Fraserburgh at 1000 on 11 February 2010 and the vessel set sail at 1500. After catching the midnight tide in the Pentland Firth, the Alba na Mara arrived at Loch Inchard at 0900 on 12 February. The day was spent working east to the head of the loch deploying the drop frame along the length and breadth of the loch, until at station 13 the density of creels halted any further TV work in that direction. At this point, the vessel retraced the path of the video survey covered earlier in the day, and at each TV site, a sediment sample on suitable Nephrops grounds was collected. After gathering footage from 13 TV sites and sediment from 11 of these stations (2 sites were found to be rock) the vessel tied up alongside Kinlochbervie pier early that evening.
The following morning in Loch Inchard a further four TV sites were surveyed and four sediment samples were taken. Various technical issues relating to the video equipment were dealt with before heading to Loch Laxford around midday. On arriving at Loch Laxford the ship experienced power distribution difficulties that resulted in only being able to carry out TV work until this issue was resolved. For the remainder of the day the vessel surveyed TV sites within Loch Laxford before anchoring at the head of the loch.

On the morning of 14 February, the video camera (model OE14-366) on the drop frame was replaced by
