Cruise period1992-04-16 — 1992-05-04
StatusCompleted
Port of departureBarry, United Kingdom
Port of returnLas Palmas, Spain
PurposeResearch
ObjectivesTo 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.
