1. To estimate horizontal drag forces (hydrodynamic and geotechnical drag) for ground gear shaped objects towed on the sea bed, with different vertical loads.
2. To measure the quantity of sediment remobilised by ground gear shaped objects.
3. To quantify the effect of sediment remobilisation by ground gear shaped objects on dissolved oxygen levels.
Alba na Mara will leave Fraserburgh on 4 October and steam towards the site at Dornoch. Sediment samples will be taken with the day grab at the work site. The rest of the survey will be dedicated to sledge sampling experiments. If work is not possible at the Dornoch area, sampling may be transferred to the Lossiemouth area. Alba na Mara will return to Fraserburgh on the 14 October, and the scientific personnel and equipment will be unloaded on the 15 October.
