PurposeResearch
ObjectivesThe objectives of this cruise were:
(1) To service the IOS current meter moorings NE of Rockall (I1-I4) and retrieve and experimental mooring deployed at 56° 49 min N, 9° 16 min W. Accomplished.
(2) To re-lay the corrosion potential current meter mooring off South Uist. Accomplished.
(3) To measure chlorophyll concentrations over the shelf and shelf-edge. Accomplished.
(4) To work CTD sections across the shelf and shelf-edge. Five sections were worked from the full Rockall via Anton Dohrn Seamount (Ellett Line) section in the south northwards to a section from off the Butt of Lewis to 60N, 10W.
