Supplemental Equipment Request for Advanced Marine Mammal Acoustic Localization

Abstract

OBJECTIVE: This award is supplemental support for a larger three-year $300K award from ONR Ocean Acoustics(N00014-03-l- 0215). The overall project goal is to modify flash-memory recorders, originally developed for marine mammal acoustic tags, into modular, portable, and rugged array systems that can be deployed in multiple configurations from inexpensive deployment platforms (i.e. boats), and even from autonomous underwater vehicles (AUVs) These arrays have been used to test various acoustic localization techniques on several marine mammal species that produce vocalizations in the 10-10000 Hz range, with an emphasis on matched-field processing (MFP) methods. MFP methods have the potential of permitting 3-D passive acoustic tracking of sound sources using a collection of sensors deployed at one location, instead of being deployed over multiple locations.
