Cruise summary report
Cruise Info. | |
Ship name (ship code) | RV Cefas Endeavour (74E9) |
Cruise identifier | 4B/03 |
Cruise period | 2003-06-25 — 2003-07-18 |
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).
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 and pore water) at NMMP sites and from additional selected sites as appropriate, e.g. Dogger Bank. 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 biota for determination of imposex and TBT analysis plus sediment for TBT analysis from shipping lanes, anchorages and reference sites in support of OSPAR requirements. |
