PurposeResearch
ObjectivesThe objectives of this cruise were:
1. Service the current meter mooring at 57N, 9W. Recovered but not relaid due to heavy fishing activity in the area.
2. Work the Rockall via Anton Dohrn Seamount (Ellett Line) hydrographic section. Accomplished.
3. Obtain live spiny crab larvae for Liverpool University Port Erin Laboratory.Net hauls successfully completed but very few crab larvae caught.
4. Work two deep stations in the Rockall Channel for particulate and trace metal analyses. One station successfully worked.
5. Lay three current meter moorings in the Sea of the Hebrides for the duration of the cruise. Only two were deployed due to equipment shortages. Both were successfully recovered.
6. Work a grid of STD stations in the Sea of the Hebrides with water bottle sampling for caesium, lead and radium isotope determination. STD grid and surface sampling completed, but only one near-bottom sample due to Niskin bottle failure.
7. Collection of large-volume surface water samples for radio-caesium measurements. Accomplished.
8. Obtain bottom grab samples for Aberystwyth University Geology Department. Shelf and Rockall Bank samples successfully obtained.
