| Status | Completed |
| Port of departure | Lowestoft, United Kingdom |
| Port of return | Lowestoft, United Kingdom |
| Purpose | Research |
| Objectives | 1. To conduct a survey of an experimentally dredged site off Norfolk, using grab, underwater camera and side-scan sonar.
2. To conduct trials with a Hamon grab using different bucket sizes. 3. To sample the sediments, benthos and fish (dab or flounder) at various North Sea NMP sites, using grab and trawl. 4. To sample a grid of stations on the Dogger Bank for a range of contaminants in sediments and benthos. 5. To deploy a Kasten core at the Silver Pitt and at other suitably muddy locations. 6. To conduct a side-scan sonar and benthos survey at an aggregate extraction site off Hastings. 7. To sample horse-mussels from the Humber/Wash area for biological and chemical analysis. 8. To conduct a bathymetric survey at a solid waste disposal site off the River Tyne, NE England. Additional aims: 1. To initiate sampling at and around aggregate dredging areas for analysis of fish gut contents. 2. To sample sediments off the Tyne as part of a temporal study of contaminant concentrations. 3. To sample the outer Thames estuary by beam trawl for litter content and benthos. |
