Objectives1. To collect CTD profiles and large volume water samples at standard positions between the Sound of Mull and the shelf edge West of Barra for radiocaesium studies.
2. To service the DML current meter mooring in the Tiree Passage.
3. To work the CTD stations of the Anton Dohrn seamount section between the shelf-edge and Rockall to continue the Rockall Trough time series as a contribution to WOCE Goal 2.
4. To work the Rockall to Malin Head CTD section for further investigation of recent water mass changes west of Britain.
5. To work shelf CTD sections in the Sea of the Hebrides and the North Channel as time permits.
6. To collect Acoustic Doppler Current Profiler (ADCP) measurements over the shelf and in deeper water in relation to geographical position.
7. To continue observational study of seabird populations west of Britain.
