StatusCompleted
Port of departureLowestoft, United Kingdom
Port of returnLowestoft, United Kingdom
PurposeResearch
Objectives1. To conduct monitoring studies at stations established under the UK National Monitoring Programme. This will involve physical measurements, and the collection of samples for chemical analysis and biological effects studies.
2. To collect water samples for the analysis of volatile organic compounds in coastal and estuarine waters, in order both to quantify Red List compounds and to intercompare purge and trap and liquid-liquid extraction methods.
3. To collect water and sediment samples for analysis of PAH in coastal and estuarine waters.
4. To deploy a solid-phase extraction system to obtain samples for the analysis of dissolved organics in coastal and estuarine waters, both to support biological effects studies and to intercompare with liquid-liquid extraction procedures.
5. To collect samples of suspended particulate material, water and sediment samples in coastal and estuarine areas for analysis of organochlorine contaminants.
6. To collect water samples in inner estuarine areas for GC/MS screening of novel organic contaminants.
7. To collect water samples in coastal areas and areas of shipping activity for the analysis of organotin compounds.
8. To conduct a survey of cadmium in seawater along a transect from the Humber to the Dogger Bank, and then to the River Tees. This is a more detailed study intended to provide information on possible sources of cadmium in the area as indicated by relatively high concentrations in fish sampled during the 1991 NTSF studies.
9. To collect samples along established pollution gradients in the German Bight for use in the development and evaluation of whole sediment bioassay techniques.
10. To collect sediments for use in the preparation of reference materials for the National Marine Analytical Quality Control Programme recently established under the UK's National Monitoring Programme.
11. To collect samples of surface sediment from the vicinity of the Rame Head dredged spoil disposal area for analysis of organochlorines.
(Aims 10 and 11 were additional aims not on the original cruise programme.)
