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 obtain water samples from the sediment plume to examine the relationship between suspended sediment load and nutrient concentration.
Alba na Mara will leave Fraserburgh on 8 May and steam towards the work site ENE of Tarbat Ness. Fifteen 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.
