| Objectives | Objectives
1. To survey dredged material disposal sites at Souter Point (Tyne), North Tyne (Tyne), Tees Bay, and Inner and Outer Gabbard (outer Thames estuary) for benthos and for trace metal and organic contaminants in sediments, using grabbing, coring and acoustic methods. 2. To apply a range of sampling methodologies at dredged material disposal and aggregate extraction sites, to assist in the development of environmental indicators for these activities. 3. To sample representative NMMP locations using grabbing, coring, acoustic and trawl methods for trace metal and organic contaminants, litter and the epi-, macro-, meio-, and micro fauna. 4. To sample surface waters at representative offshore and intermediate NMMP locations for salinity, nutrients and chlorophyll. 5. To sample the benthos and sediments for time-series studies using the Hamon grab, in the vicinity of aggregate extraction sites off the Isle of Wight and Lowestoft. 6. To conduct time-series studies at gravelly locations following cessation of aggregate dredging, using grabbing and acoustic techniques. 7. To sample horse-mussels from the Humber/Wash area for later analyses of contaminants in flesh. 8. To conduct habitat mapping surveys at a range of sites impacted by anthropogenic activities using grabbing, coring, trawling, photographic and acoustic techniques. 9. To carry out a short sidescan sonar survey at an aggregate extraction site in the outer Wash. 10. To sample the Tyne temporal transect at the historic sewage sludge disposal site. |
