| Status | Completed |
| Port of departure | Lowestoft, United Kingdom |
| Port of return | Lowestoft, United Kingdom |
| Purpose | Research |
| Objectives | 1. To undertake process measurements at sites in the Thames estuary, southern North Sea and Wash to determine the impact of land derived nutrients on the marine ecosystem.
2. To undertake spatial surveys to determine the distribution of nutrients, phytoplankton indicators and other relevant parameters using CTD and underway sampling in the outer Thames estuary, southern North Sea and Wash. 3. To make supporting bio-optical measurements at sites in the southern North Sea (CSG extra-mural). 4. To conduct trials of a prototye Smart Mooring at the Outer Gabbard site. |
