Cruise summary report
| Cruise Info. | |
| Ship name (ship code) | RV Cirolana (74CZ) |
| Cruise identifier | CIR11/96 |
| Cruise period | 1996-12-02 — 1996-12-22 |
| Status | Completed |
| Port of departure | Lowestoft, United Kingdom |
| Port of return | Lowestoft, United Kingdom |
| Purpose | Research |
| Objectives | One of a series of cruises to study:
1) The properties of real dredged material at two key sites (Harwich Tower and Tees Bay. 2) Environmental monitoring and research relating to the distribution and behaviour of radionuclides in the water column and sediments of UK waters. Main tasks: A) To deploy instruments, obtain core samples and carry out side scan surveys in two locations (Harwich Tower and Tees Bay). B) To collect and process surface/bottom seawater and sediments for the analysis of TC-99 and transuranic radionuclides, as part of post-EARP surveys. C) To collect and process surface water for analysis of SS and tritium for the biennial monitoring programme. |
