Abstract : This project was aimed at an understanding of the Q structure of oceanic crust, the lateral variability of that structure, the relationship between Q and seismic velocity within oceanic crust, and the effect of both the mean structure and the superimposed variations on the mode and efficiency of seismic energy propagation. Specifically, we applied seismic tomographic techniques to determine quantitatively the three dimensional seismic attenuation structure of the oceanic crust, with specific application to an existing data set from a tomography experiment conducted on the East Pacific Rise with a network of ocean bottom seismometers and hydrophones.
