In the late 1960s and early 1970s, Durham University with the Royal Navy, and the Atlantic Oceanographic and Meteorological Laboratories of NOAA, Miami, conducted an extensive marine geophysical survey programme over the eastern margin of the Caribbean Sea (10° N - 17° N, 57° W - 65° W) as part of the Cooperative Investigation of the Caribbean and Adjacent Regions (CICAR). Bathymetry, magnetics (total field and magnetic anomaly) and gravity (free air and Bouguer anomaly) data were collected. Bathymetry was monitored mostly by conventional sonic transducers (with the exception of the 1971-1972 NOAA lines, most of which were done with a narrow-beam transducer), the total magnetic field by proton precession magnetometers, and the gravity by Graf- Askania or LaCoste-Romberg sea gravity meters.
