Cruise summary report
| Cruise Info. | |
| Ship name (ship code) | RV Cirolana (74CZ) |
| Cruise identifier | CIR5B/01 |
| Cruise period | 2001-06-16 — 2001-07-16 |
| Status | Completed |
| Port of departure | Lowestoft, United Kingdom |
| Port of return | Lowestoft, United Kingdom |
| Purpose | Research |
| Objectives | 1. To collect samples of demersal fish for chemical analysis from the North Sea,
Eastern English Channel and Irish Sea in support of UK National Marine Monitoring Programme (NMMP) and EC Fish Products Directive Work. 2. To collect water samples for NMMP biological effects studies and to deploy fractionation/bioassay techniques on water samples from offshore and near shore/estuarine locations. 3. To collect sediment samples for biological effects studies (whole sediment) at NMMP sites and from additional selected sites as appropriate. 4. To collect fish samples at NMMP sites, for fish disease and genetic toxicological analysis (e.g. DNA adducts). 5. To further investigate the use of appropriate biochemical, cytochemical and other biological techniques in support of NMMP. 6. To sample representative offshore NMMP locations using grab, core, and trawl for trace metal contaminants, PAHs and other organic contaminants (including nonylphenols, flame retardants and HCs) and the benthic fauna. 7. To collect NMMP summer water samples for nutrients, salinity and chlorophyll analysis. 8. To collect fish cages, water and biota samples as part of the ICES/IOC BECPELAG workshop and in support of studies to investigate the significance of offshore chemicals as endocrine disrupters in fish. 9. To assess the potential for UV-light to increase the toxicity and/or genotoxicity of seawater samples to invertebrate bioassay organisms. ADDITIONAL AIMS: 10. To carry out sampling at a selection of stations previously worked as part of the ICES 1986 North Sea Benthos Survey. 11. To record items of litter collected in all deployments of the Granton trawl. |
