| Purpose | Research |
| Objectives | 1. To conduct a baseline survey of concentrations of trace metals in seawater from coastal and offshore areas. This completes the survey begun on CLIONE 4/85 carried out in connection with the ICES Baseline Survey of Contaminants.
2. To carry out a preliminary survey of cadmium and mercury concentrations in seawater around the sewage sludge and dredged spoil disposal sites, prior to an in-depth survey of their distribution in Liverpool Bay. 3. To analyse samples of coastal and offshore water from various locations for hydrocarbons, also as an input to the ICES survey (Aim 1). 4. To collect samples of suspended particulate material from 1 or 2 sites in the eastern Irish Sea for hydrocarbon analysis, in connection with studies of the impact of development of the Morecambe Bay gas field. 5. To recover the NBVR tetrapod, currently deployed off St Bees Head. 6. If time allows, to recover, service and replace current meter arrays (6) currently deployed in the eastern Irish Sea. |
