PurposeResearch
Objectives1. To service the POL ADCP mooring in the North Channel on the passage north from Barry to Campbeltown.
2. To work the CTD stations of the Anton Dohrn Seamount (Ellett Line) section, between the shelf-edge and Rockall in order to continue the Rockall Trough time-series as a UK contribution to WOCE Goal 2.
3. To recover and redeploy a temperature-salinity recorder and thermistor chain at station M of the Anton Dohrn Section.
4. To service the DML current meter mooring in the Tiree Passage.
5. To sample benthos at Station M using the epibenthic sled and the Agassiz trawl.
6. To collect a suite of physical, nutrient and biological profiles and samples, including multi-coring, at the shelf-edge west of Barra as part of the LOIS pilot studies.
7. To work shelf-edge - Sound of Mull CTD section, with nutrient and tracer sampling.
8. To collect grab samples of the bottom deposits at stations 1D to 4D west of Islay for SURRC analysis.
9. To work the PROFILE sampling stations around the Arran deep, as time permits.
