PurposeResearch
ObjectivesCruise objectives were.
(1) Re-establish the current meter mooring at 57N, 9W and lay another NW of St Kilda. Accomplished.
(2) Lay four Wormley and one Bidston moorings at JASIN stations in the northern Rockall Channel/ Rockall Bank. Accomplished
(3) STD time series at apices of 15km triangles centred on the JASIN moorings. Two profiles taken at each apex around the three Wormley moorings on each of three days.
(4) Test and make measurements with the Heidelberg apparatus for determining air-sea interface excahnge rate by 222 Radon deficit. Accomplished.
(5) Work the Anton Dohrn Seamount (Ellett Line) STD section. Accomplished.
(6) Work a series of 25-hour STD time series stations to 1200m depth. One 12-hour station (1.5 hour sampling) worked.
(7) Record along-track temperature and salinity using the STD in a pumped flow on-deck with 10-minute bathymetric depth soundings. Accomplished.
(8) Collect large-volume surface water samples for radiocaesium analysis. Accomplished with STD profiles on all but one station.
