RRS Challenger CH9C/80
Cruise summary report
| Cruise Info. | |
| Ship name (ship code) | RRS Challenger (74CH) |
| Cruise identifier | CH9C/80 |
| Cruise period | 1980-06-08 — 1980-06-17 |
| Status | Completed |
| Port of departure | Ardrossan, United Kingdom |
| Port of return | Barry, United Kingdom |
| Purpose | Research |
| Objectives | 1. To test the assertion that mean currents in the uppermost few metres of the wave field can in principle be measured adequately using vector averaging current sensors mounted on a moored, surface following buoy.
2. To test an experimental mooring designed for this purpose, and to investigate its suitability for mooring arrays of pitch/roll wave buoys. 3. To see whether the technique provides sufficient accuracy for current shear to be detected in the near surface region. 4. To provide further testing for the vector averaging electromagnetic current meter recently developed at IOS. 5. To provide independent measurements in the open sea against which the performance of the UK data buoy wave and current sensors can be assessed. |
