Acoustic noise interferometry in the Straits of Florida at 600 m depth: Preliminary results. Journal Article uri icon

Overview

abstract

  • A field experiment designed to test the feasibility of noise interferometry was conducted in the Florida Straits in September/October 2013 in water of approximately 600 m depth. Ambient noise was recorded concurrently on three moored near-bottom instruments with horizontal separations of approximately 5 km, 10 km, and 15 km. Consistent with theoretical predictions, coherent sums (stacks) of many realizations of ambient noise at two measurement locations are shown to yield approximations to deterministic Green's functions that describe propagation between the two locations. Ray- and mode-based simulations of approximations to Green's functions are compared to measured stacked cross-correlations. [Work supported by NSF and ONR.].
