Cruise summary report
| Cruise Info. | |
| Ship name (ship code) | RRS Charles Darwin (74AB) |
| Cruise identifier | CD67 |
| Cruise period | 1992-04-16 — 1992-05-04 |
| Status | Completed |
| Port of departure | Barry, United Kingdom |
| Port of return | Las Palmas, Spain |
| Purpose | Research |
| Objectives | To make a seismic reflection and wide-angle seismic refraction survey using ocean bottom seismometers (OBS) and disposable sonobuoys of a 100 x 100 km study area of Mesozoic oceanic crust which had already been surveyed during earlier cruises.
Any remainder of the time on station was used to fill in critical gaps in the earlier magnetics and gravity surveys. |
