Abstract
We have demonstrated with ocean acoustic data and associated theory and land seismic data that the Green’s functions between pairs of receiving sensors can be obtained from a long‐time correlation process. Noise data from fixed acoustic and seismic sensors can be used to study the ocean structure, the ocean bottom structure below the sensor field, and the earth structure between ocean sensors and land sensors hundreds to thousands of kilometers away. We have already performed extensive seismic noise tomography using land sensors in Southern California in which the major noise component originated in the ocean. We present the previous data analysis that demonstrates the feasibility of this concept.
