Purpose

Research

Objectives

1. 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 (Ellett Line) 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 large volume water samples west of the Hebrides and samples for iodine concentration determination.
