Cruise summary report
| Cruise Info. | |
| Ship name (ship code) | RRS Discovery (74E3) |
| Cruise identifier | D230 |
| Cruise period | 1997-08-07 — 1997-09-17 |
| Status | Completed |
| Port of departure | Vigo, Spain |
| Port of return | Southampton, United Kingdom |
| Purpose | Research |
| Objectives | 1. Repeat survey of IGY Section 4 (Portugal to Greenland), for climate change analysis.
2. Determination of heat, mass and freshwater fluxes across IGY Section 4, and across northern 'closure' sections: thus, exchanges between the Sub-Polar Gyre and (to the north) the Nordic Seas, and (to the south) the Sub-Tropical Gyre. 3. Continuation of the Ellett Line time series section across Anton Dohrn Seamount. 4. Production of data suitable for inclusion in the WOCE North Atlantic data set. |
