Objectives | Objectives
1. To collect biota samples for TBT analysis using whelk pots at the Peterhead dredged material disposal site. 2. To undertake underwater television (UWT), grab and RoxAnn surveys at the Peterhead dredged material disposal site to assess the condition of the seabed, identify the predominant benthic epifauna species, and the distribution of man-made debris. 3. To undertake Agassiz, UWT, grab and RoxAnn surveys at two potential sea disposal sites off Whitehills. 4. To undertake Agassiz, grab, RoxAnn and UWT surveys at potential Aberdeen offshore windfarm site. 5. To undertake sediment sampling and where possible UWT surveys off Invergordon and at the Sutors sea disposal site. 6. To undertake Agassiz, grab, RoxAnn and UWT surveys at dredged material disposal sites around Orkney, a maximum of five sites to be investigated. 7. To undertake grab, RoxAnn and UWT surveys at EMEC renewables test centre off Orkney (two sites). Narrative Departure from Fraserburgh Harbour on the 4 April was delayed by 24 hours due to poor weather. The following morning passage was made to Peterhead disposal site. On arrival at the disposal site, three UWT transects were successfully completed. The deployment of the Agassiz trawl failed due to stoney ground in and around the disposal site. Ten buckie pots were deployed. Buckie pots were located to the north, within and to the south of the disposal. The local SFPA Office and the Peterhead Port Authority were notified of their deployment for a maximum period of 24 hours and their perimeter coordinates. Six grab sediment sample stations were attempted before passage was made for Peterhead Harbour. The following morning a Sholkowitz core was successfully deployed while berthed at Peterhead Harbour. After requesting access from the harbourmaster, a second attempt was made within the entrance basin of the harbour. |
