Long range scientific objectives are to understand the variations of the oceanic crust as expressed by variabilities in its seismic velocity structure. Such variations occur both with geological age caused by hydrothermal alteration and pore sealing and spatially, such as, distance along-ridge variations caused by ridge segmentation, faulting, hydrothermal cells, etc. For this project I have developed and applied seismic waveform inversion methods that allow variations in seismic velocities from independent seismic data sets to be quantified. The flexibility of this approach allows independent data from two sites to be jointly analyzed for velocity variations, as well as P and S data to be analyzed in order to constrain Poissons Ratio.
