Relating Acoustic Backscatter Data to the Geomorphology of the Mid-Atlantic Ridge
Abstract
In this work an attempt is made to invert backscatter data collected on the Acoustic Reverberation Special Research Project (ARSRP) Reconnaissance Cruise to extract fine- and micro-scale geomorphology of a site on the western flank the Mid-Atlantic Ridge. To achieve this goal a methodology was developed and tested using two numerical models of different fidelity and computational load. Both models are based on the Helmholtz-Kirchhoff (H/K) theory for near- normal incidence. The inversion method was then applied to the ARSRP reconn data to extract the Mid-Atlantic Ridge geomorphology. Preliminary results and problems with using the ARSRP reconn data for this analysis are discussed. A proposal to modify the measurement methodology for some of the planned data collection in the upcoming ARSRP experiment is made. Bottom scattering, Reverberation.
