Short name | CH6A/81 |
Objectives and Narrative |
The objectives of this cruise were:
(1) To service current meter moorings at station R (shelf: 57N, 9W) and re-lay current meter moorings at stations M (deep water: 57 deg 18 min N, 10 deg 23 min W) and F (deep water: 57.5N, 12.25W). Accomplished. (2) To sample benthos in the southern and central Rockall Trough. Successful epibenthic sled and Agassiz trawl hauls at the SMBA permanent station and station M. (3) To recover the corrosion potential current meter mooring off South Uist. Accomplished. (4) To work the Rockall via Anton Dohrn Seamount (Ellett Line) CTD section. Stations R (shelf) to O (deep water between the slope and the seamount) of the section worked. Additional CTD sections on the shelf worked from Loch Moidart past Oigh Sgeir and at right angles into Loch Bracadale, Skye. (5) To determine bottom topography at future mooring sites to the west of Porcupine Bank. Accomplished. (6) 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 on all but one station. |
