PurposeResearch
Objectives1. To work the CTD stations of the Anton Dohrn Seamount (Ellett Line) section between the shelf-edge and Rockall to continue the Rockall Trough time-series as a UK contribution to WOCE Goal 2.
2. To moor a temperature-salinity recorder and thermistor chain at station M of the Anton Dohrn Section.
3. To collect a suite of profiles, samples and cores at the shelf-edge west of Barra to continue DML LOIS Shelf-Edge Study (SES) pilot surveys.
4. To service the DML current meter mooring in the Tiree Passage.
5. To work selected stations of the Malin Head - Rockall CTD section for further investigation of recent water mass changes west of Britain.
6. To work shelf CTD, nutrient and coring stations in the Firth of Clyde as part of the DML/UCNW MAST 2 PROFILE programme.
7. An additional aim was a request received from Professor Simpson just before sailing for the redeployment of a current meter mooring and guard marker in the outer Firth of Clyde.
