Purpose | Research |
Objectives | 1. To sample the sediments, benthos and fish at various NMP sites in the Irish Sea and English Channel by grab and trawl.
2. To deploy a Kasten core at suitable muddy locations. 3. To sample aggregate areas in Liverpool Bay, the Bristol Channel and Lyme Bay as part of a continuing MAFF/CEC study. 4. To sample sediments at sewage-sludge disposal sites off Plymouth and the Isle of Wight. 5. To conduct further studies at an aggregate extraction site off Hastings using underwater camera, side-scan sonar and dredges. 6. To sample a grid of stations on the Dogger Bank for a range of contaminants in sediments and benthos. Additions: 1. To examine the distribution of the 'ross worm' Sabellaria at a proposed aggregate extraction site in the Bristol Channel. 2. To sample the sediments and benthos at the Lyme Bay sewage-sludge disposal site. 3. To conduct a side-scan sonar survey off Ramsgate at a location thought to have been used for illegal disposal of dredged material. |
