Cruise summary report

Cruise Info. 
Ship name (ship code)RRS Discovery (74E3)
Cruise identifierD230
Cruise period1997-08-07 — 1997-09-17
StatusCompleted
Port of departureVigo, Spain
Port of returnSouthampton, United Kingdom
PurposeResearch
Objectives1. 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.
