Cruise summary report
| Cruise Info. | |
| Ship name (ship code) | RRS Discovery (74E3) |
| Cruise identifier | D247 |
| Cruise period | 2000-06-05 — 2000-07-03 |
| Status | Completed |
| Port of departure | Southampton, United Kingdom |
| Port of return | Southampton, United Kingdom |
| Purpose | Research |
| Objectives | Acquire finely sampled measurements of currents and hydrography in the Faroe Bank Channel region, sufficient to address three specific questions:
1) What is the transport and momentum balance of the overflow? 2) How does the overflow water approach the sill southwest of the Faroe Islands, and is the overflow hydraulically controlled? 3) Where and how does mixing occur in the descending overflow? |
