PurposeResearch
ObjectivesCruise objectives were.
(1) Service the current meter mooring at 57N, 9W and recover another NW of St Kilda. Accomplished.
(2) STD time series at apices of 15km triangles centred on the JASIN moorings and Anton Dohrn Station F. Completed for Station F and two of the moorings plus five of six profiles on a third mooring before bad weather set in. One mooring not worked.
(3) Make shear measurements with the Royal Australian Navy Gradient Richardson number meter. Accomplished.
(4) Work the Anton Dohrn Seamount (Ellett Line) STD section. Accomplished.
(5) Work a series of 25-hour STD time series stations to 1200m depth. Not possible due to weather.
(6) Record along-track temperature and salinity using the STD in a pumped flow on-deck with 10-minute bathymetric depth soundings. Accomplished.
(7) Repeat the shelf-edge STD stations worked on RRS Challenger cruise 10/77. One of the shelf-edge sections (Barra Head) worked.
(8) Collect large-volume surface water samples for radiocaesium analysis. Accomplished with STD profiles.
