| Cruise period | 2001-07-19 — 2001-08-01 |
| Status | Completed |
| Port of departure | Belfast, United Kingdom |
| Port of return | Belfast, United Kingdom |
| Purpose | Research |
| Objectives | 1. To service the DARD mooring in the western Irish Sea.
2. To investigate the near surface distribution of temperature, salinity and chlorophyll in the Irish Sea. 3. To investigate zooplankton abundance and species composition in relation to environmental variables in the Irish Sea. 4. To relate estimates of primary production to satellite imagery. 5. To undertake a preliminary study of the distribution of stable isotopes in the plankton and benthos in different regions of the Irish Sea. 6. To investigate the distribution of heavy metals associated with suspended particulate material. |
