PurposeResearch
ObjectivesThe objectives of this cruise were:
(1) To service the current meter moorings at station M (Rockall Channel), Y (Tiree Passage) and J (Sound of Jura).
(2) To collect radiocaesium samples with CTD profiles on shelf sections from Mull of Galloway in the south to the Butt of Lewis in the north. Eleven sections worked.
(3) To sample chlorophyll and nutrients across the shelf and the slope to the west of the Hebrides. Three sections sampled plus continuous underway fluorometer.
(4) To service two UCNW shelf moorings and recover three more. Accomplished.
(5) To relocate current meter moorings and the Dundee satellite-interrogated temperature buoy (Kraksat).on the Hebridean Slope section west of South Uist to terrain less suited to fishing. Three of five current meter moorings plus Krakstat relocated.
(6) To recover an IOS Bidston tide gauge from mooring M in the Rockall Channel. Accomplished.
(7) To observe seabirds around the Hebrides. Accomplished.
(8) To work the Rockall via Anton Dohrn Seamount (Ellett Line) CTD section. Accomplished.
