Cruise summary report
| Cruise Info. | |
| Ship name (ship code) | RV Corystes (74RY) |
| Cruise identifier | COR09/04 |
| Cruise period | 2004-07-04 — 2004-07-19 |
| Status | Completed |
| Port of departure | Lowestoft, United Kingdom |
| Port of return | Lowestoft, United Kingdom |
| Purpose | Fisheries |
| Objectives | 1. To use acoustic & fishing survey methods to estimate the abundance and distribution of sandeels on sandeel fishing grounds on the North West Riff (Dogger Bank) & The Hills.
2. To use fishing survey methods to estimate the abundance and distribution of predatory fish feeding on sandeels on the on the North West Riff & The Hills. 3. To use fishing survey methods (Bongo net) to estimate the abundance and distribution of plankton on the sandeel fishing grounds on the North West Riff & The Hills. 4. To use QTC to aid in describing sediment type in relation to sandeel distribution and abundance on the sandeel fishing grounds on the North West Riff & The Hills. 5. To perform seabird surveys at sampling stations. 6. To perform side-by-side comparative sampling with RV Endeavour 08_04. Work will involve comparing the performance of biological sampling gears in shallow water (~20m; Grid 1, transects 1K & 1L), mid water (20-40m; Grid 1, transect 1G & 1H) and deep water (40m+; Grid 2, transect 2A & 2 B) water. |
