Tomographic & Geophysical Inversions from Opportunistic Sound Sources

Abstract

The fundamental goal is to develop an advanced passive acoustic monitoring system that can be used to characterize ocean acoustic phenomena in ocean regions that are currently too isolated or remote to justify expensive exploratory research, and to provide cost-effective means to conduct field research into advanced coherent beamforming and geoacoustic inversion methods The work also seeks to stimulate the further development of low-cost, low-power, autonomous acoustic recorders, by demonstrating how passive acoustic time-synchronization techniques can effectively convert a set of these recorders into a coherent beamforming array.
