|Cruise period||1981-01-26 — 1981-02-04|
|Port of departure||Dunstaffnage, United Kingdom|
|Port of return||Barry, United Kingdom|
|Objectives||The objectives of this cruise were:
(1) To service current meter moorings at stations M, (deep water: 57° 18 min N, 10° 23 min W) and R (shelf: 57N, 9W) and re-lay the mooring at F (deep water: 57.5N, 12.25W. Mooring at R recovered and re-laid: mooring at M recovered: no work at F.
(2) To work the DML Rockall via Anton Dohrn Seamount (Ellett Line) CTD section and other sections across the Rockall Channel. Stations R (shelf) to M (deep water between the slope and the seamount) of the primary section worked plus a section across the shelf west of South Uist.
(3) To deploy a corrosion potential current meter mooring off South Uist. Accomplished.
(4) To collect large-volume surface water samples for radiocaesium analysis, accompanied by CTD profiles, at stations across the Scottish continental shelf. Accomplished with CTD profiles at all but one station.
