Objectives

The objectives of this cruise were:
(1) To deploy three current meter moorings in the North Channel for the duration of the cruise. Re-lay one of the three for recovery by RV Clione. Moorings deployed and recovered, but no data from one due to collapse of the sub-surface buoyancy. Redeployment accomplished.
(2) To work CTD sections across the shelf from the Mull of Galloway and the North Minch. Fifteen sections worked with five covering the North Channel, three between the Outer Hebrides and the shelf edge and seven between Hebridean islands and the mainland.
(3) To collect large-volume water samples for radiocaesium analysis from three depths at each of the ten standard stations between the Sound of Mull and the shelf edge. Accomplished.
(4) To collect nutrient, chlorophyll and phytoplankton production data on the outer shelf and slope. Accomplished.
(5) To deploy a current meter mooring at station Y in the Tiree Passage. Accomplished.
(6) To visit current meter moorings at F, M, V and W to recover any surviving equipment and re-lay mooring F. Nothing found. Mooring re-deployed.
(7) To search for the Dundee University Kraksat satellite-interrogated buoy. No trace found.
(8) To work the Rockall via Anton Dohrn Seamount (Ellett Line) CTD section. Accomplished from the shelf edge to Rockall Bank.
