1. To estimate horizontal drag forces (hydrodynamic and pelodynamic drag) for ground gear shaped objects towed on the sea bed, at different towing angles and vertical loads.
2. To measure the quantity of sediment remobilised by ground gear shaped objects.
Alba na Mara will leave Fraserburgh on 4 October and steam towards Lossiemouth. Tows will be carried out on clean sandy ground between Lossiemouth and Burghead, to test the new BIGG sledge to ensure its stable during deployment, and allow the crew to practice handling the sledge on deck. Sediment samples will be taken with the day grab at both the "Lossiemouth" and "Nairn" sites. The rest of the cruise will be dedicated to sledge sampling experiments. Alba na Mara will return to Fraserburgh on 12 October and the scientific personnel and equipment will be unloaded on 13 October.
