| Status | Completed |
| Port of departure | Swansea, United Kingdom |
| Port of return | Lowestoft, United Kingdom |
| Purpose | Research |
| Objectives | 1. To survey dredged material disposal sites at Swansea Bay, Nab Tower (Isle of Wight), Roughs Tower (outer Thames estuary), Tees and Tyne (Souter Point) for trace metal contaminants, TBT, PAHs, nonylphenols, flame retardants and benthos, using grab and acoustic methods.
2. To conduct a characterisation survey at the Falmouth dredgings disposal site by means of grab, trawl, side-scan sonar and underwater camera. 3. To obtain meiofauna samples at inshore muddy sites near to major estuaries. 4. To sample representative offshore NMMP locations using grab, core and trawl for trace metal contaminants, nonylphenols, flame retardants and the banthic fauna. 5. To sample representative offshore NMMP locations for nutrients, chlorophyll and phytoplankton species. 6. To conduct surveys at aggregate extraction sites off the Isle of Wight and Lowestoft using grab, beam trawl, dredge and acoustic techniques. 7. To conduct pilot sampling at gravelly locations in the English Channel for later habitat mapping, including trials with a Rallier du Baty dredge. 8. To conduct a survey of the benthos and sediments at the Thames sewage-sludge disposal site. |
