PurposeResearch
ObjectivesThe objectives of this cruise were:
(1) Re-establish the shelf current meter mooring at 57N, 9W. Not possible due to bad weather.
(2) Work the Rockall via Anton Dohrn Seamount (Ellett Line) STD section. Worked except for station Q with increased spacing between stations.
(3) Work STD sections across the southern Rockall Channel and its entrance. A section of 11 stations along 52.5N between 21W and 14W and a section of 9 stations from Porcupine Bank to Rockall Bank were worked.
(4) Release a drifting buoy bearing a wave recorder and thermistor chain on the site of OWS JULIETT (52.5N, 20W). Accomplished.
(5) Collect large-volume surface water samples on the Scottish shelf for radiocaesium analysis. Accomplished with STD profiles at all but one station.
