| Cruise period | 2004-08-12 — 2004-08-25 |
| Status | Completed |
| Port of departure | Lowestoft, United Kingdom |
| Port of return | Lowestoft, United Kingdom |
| Purpose | Research |
| Objectives | 1. To apply a range of sampling methodologies at a number of aggregate extraction sites, to assist in the development of environmental indicators for these activities.
2. To sample the benthos and sediments from sites in the eastern English Channel and Humber/Wash areas to instigate time-series studies using the Hamon grab. 3. To conduct time-series studies at gravelly locations following cessation of aggregate dredging, using grabbing, trawling, photographic and acoustic techniques. 4. To sample a number of aggregate extraction sites using various grab, trawl, photographic and acoustic techniques to identify suitable experimental sites for future rehabilitation/restoration studies. |
