Abstract
This thesis explores the potential advantage of deep ocean trench placement of an acoustic sensor network. The hypothesis is that a hydrophone deployed in a deep ocean trench will operate in an environment of reduced ambient noise such that passive maritime surveillance may be performed with relatively high signal-to-noise ratio (SNR). Barrier or "tripwire" coverage along the oceanic trench is made possible by virtue of networked acoustic communication among widely spaced hydrophones. Physics-based hydro-acoustic propagation modeling supports analysis of target-to-sensor propagation and networked acoustic communication links in representative trench environments.
