Velocity Spectral Estimates from the Arrays of the ROSE Program
The ROSE (Rivera Ocean Seismic Experiment) was a large seismic/ acoustic program conducted near the Clipperton Fracture Zone in Jan/Feb 1979 off the western coast of Mexico. Ten oceanographic institutions and Navy laboratories, deployed over seventy ocean bottom seismometers/hydrophones, two vertical hydrophone arrays and a 24 channel towed hydrophone array over approximately 120 nm × 120 nm area near the East Pacific Rise. Explosive sources ranging in weight from.1kg to 1000 kg generated signals that propagated through the water and seabed and were recorded by these instruments. Seismically the experiment focused upon determining the characteristics of the crust near an active plate boundary. Acoustically it concerned analyzing low frequency propagation within a thinly sedimented seabed.
