Cruise Inventory Information
| Long name | RRS James Clark Ross (74JC) cruise JR19930203 (JR04) |
|---|---|
| Short name | JR19930203 (JR04) |
| Objectives and Narrative |
The main tasks were:
1. 3 weeks of coring in the Falkland Trough, central Scotia Sea and NW Weddell Sea, to study glacial/interglacial circulation changes. 2. A similar period of marine geophysical investigation of the Bellingshausen Sea Basin around Peter 1 Island. 3. A similar period of dredging along the axis of Bransfield Strait, for geochemical analysis. 4. En passant, refuelling the Signy Island Station and recovering 2 geological field parties from S Shetland Island sites. |
