Objectives

The objectives of this cruise were:
(1) To service the current meter mooring at 57N, 9W and the corrosion potential current meter mooring off South Uist. Current meter mooring recovered and re-laid. South Uist mooring recovered, but not re-laid.
(2) To make an extensive CTD survey of the Scottish Coastal Current between the North Channel and Cape Wrath, including large-volume surface sampling for radiocaesium analysis. Large number of CTD sections worked, covering the whole of the NW Scottish shelf, including a section of the eastern Ellett Line.
(3) To collect sediment cores with the WHOI tripod at locations along the axis of the Scottish Coastal Current. Cores obtained at five of six planned sites.
(4) To measure chlorophyll concentrations over the shelf and shelf-edge. Accomplished.
(5) To work two CTD sections across the continental slope. Accomplished.
(6) To collect large-volume surface water samples for radiocaesium analysis. Accomplished.
