| Long name | RRS Challenger (74CH) cruise CH12A/75 |
|---|---|
| Short name | CH12A/75 |
| Objectives and Narrative |
The cruise had 6 objectives.
1. Recovery and relaying of a current meter mooring at 57N 9W. 2. Working the hydrographic sections to Anton Dohrn Seamount (Ellett Line) and Rockall and Rockall-Malin Head (Rosemary Bank to St Kilda also worked due to favourable conditions). 3. Using a submersible pump and autoanalyser for nutrient determinations along these sections. 4. Collecting Shipek grab samples of shelf sediments for Aberystwyth University. 5. Collecting large volume water samples for radio-caesium analysis by the Fisheries Radiobiological Laboratory. 6. Transmitting temperature profiles to the Met Office at Bracknell based on STD traces. All objectives were successfully achieved. |
