DESCRIPTION OF THE DATA
Data are for trawling experiments carried out in the Dornoch Firth area, Scotland for the years 2015, 2016 and 2017. Data were used in the thesis: "Investigating how benthic trawl gear design and location affect the resuspension of sediments and dissolved nutrients from the seafloor".

Data in the 2015 file includes trawl component type (dimensions of the roller) and associated drag and pressure, and the resulting nutrient and Particle Size Distribution (PSD) data at different heights of the seafloor. Samples were collected at the Hollows and Dornoch Bay sites in the Dornoch Firth area on the 08/05/2015.

Data in the 2016 file includes trawl component type (dimensions of the roller) and associated drag with consistent pressure (no added weights), and the resulting nutrient and Particle Size Distribution (PSD) data at different heights of the seafloor. Samples were collected at 6 sites: Banff, Hollows, Dornoch offshore, Lossie, Lossie prawn fishery and Dornoch offshore, between the 26/08/2016 to 04/10/2016.

Data in the 2017 file includes a single trawl component type (400 Block, 600 long) and associated drag with added weights to simulate increasing pressure on the seafloor (tied up, 0kg, 60kg, 120kg). The resulting nutrient and Particle Size Distribution (PSD) data at different heights of the seafloor are reported. Samples were collected at 6 different sites: 2 at Banff-Buckie, 3 in the area of Lossie-Burghead and 1 at Dornoch. Trawls were conducted between the 01/08/2017 and 08/08/2017.
