Cruise summary report
| Cruise Info. | |||||||||
| Ship name (ship code) | RRS Discovery (74E3) | ||||||||
| Cruise identifier | D94_3 | ||||||||
| Cruise period | 1978-08-20 — 1978-09-17 | ||||||||
| Status | Completed | ||||||||
| Port of departure | Glasgow, United Kingdom | ||||||||
| Port of return | South Shields, United Kingdom | ||||||||
| Purpose | Research | ||||||||
| Objectives | 1. To launch and track a drifing Spar carrying current meters from 14 to 50m depth.
2. To track near surface floats measuring Lagrangian shear, dispersion and vertical velocities. 3. To conduct batfish surveys in the depth range 0 to 80m. 4. To make directional wave measurements in conjunction with SEASAT passes and aircraft overflights. All these tasks were accomplished with a substantial degree of success. | ||||||||
