Description
Summary:In this final report we summarize research accomplished on the project titled, Location, Characterization and Quantification of Hydroacoustic Signals in the Indian Ocean. Our initial goals were to locate, characterize and quantify hydroacoustic signals recorded on the three available hydroacoustic stations in the Indian Ocean, and this was accomplished for available data through May 2003. However, shortly thereafter our contract was rescoped to focus on high frequency propagation through the convergence zone and blockage. Therefore our work includes results from the 2002 characterization and quantification of observed signals, as well as a detailed analysis of high frequency ice-related signals originating from Antarctica and the blockage of high frequency energy associated with a particularly large earthquake. The original document contains color images.
