PurposeResearch
ObjectivesAssessing the impact of different fishing intensities on the benthos on the Fladen Ground. Areas of different fishing intensities will be sampled for infauna using box corers and/or day grabs. A 2-m beam trawl will be used to sample epifauna and habitat features. Each box will be side scanned to monitor trawl marks on the sea floor which can give an indication of recent fishing events.
RV Prince Madog sailed on 15/6 at 9:30 and arrive on the first station at the Fladen ground only 3 h behind schedule due to strong winds on the North Sea at 20:00 on 17/6. Box A was sampled with the 2m-beamtrawl (3) and daygrab (5). The swell did not allow use of the boxcore. Side scanning of box A commenced at 23:00 and was completed for box A. After this the side-scan sonar did not give a signal anymore, probably because the whole wire (350 m) had been paid out to come close to the bottom (150 m On 18/6 box B, C, and D were sampled with the beamtrawl and daygrab. On 19/6, the wind had been strong in the night (up to F7), but at the weather improved during the day, station E, G, H and I were sampled. At 20:00 sampling was finished, and the ship steamed overnight to Peterhead to arrive at 6:30. We left Peterhead on 21/6 after lunch and arrived on site at 21:15 h. As gales were predicted for 23/6, we decided to make sample through the night, and sampled box K, J, F, M, N and O with the beamtrawl and daygrab. On station L only daygrab samples, but no beamtrawl samples, were taken as gales were predicted soon at 18:00, and the captain decided we had to leave immediately to make it back to Peterhead harbour before a NE gale would prevent entering the harbour. We arrived in Peterhead on 1:30 on 23/6.
In total 14 stations were sampled with the beamtrawl, 15 with the daygrab, 2 with the boxcore, 3 with the still camera and 1 with the side scan sonar.
