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 stony 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.
