1. To estimate horizontal drag forces (hydrodynamic and geotechnical drag) for cylindrical objects towed on a variety of sea bed types.
2. To measure the quantity of sediment remobilised by cylindrical objects towed on a variety of sea bed types.
3. To obtain water samples from the sediment plume to examine the relationship between suspended sediment load and nutrient concentration, from a variety of sea bed types.


Equipment will be loaded onto MRV Alba na Mara at Fraserburgh on 23 August 2016, where the sledge will be connected with the towing bridle to the central warp. Instrumentation will be prepared ready for attachment to the sledge on the sailing day. Alba will leave Fraserburgh on 26 August and steam towards one of the work sites. If weather and sea state permit, the Banff site will be sampled first, then Lossiemouth, Hollows, Dornoch offshore and then finally Findhorn. Nine sediment samples will be taken with the day grab at each work site before commencing sledge sampling. Once sampling is complete at a site, Alba will move onto the next work site. Alba will return to Fraserburgh on the 03 September, and the scientific personnel and equipment will be unloaded on the 04 September.
