Passive Autonomous Acoustic Monitoring of Marine Mammals: System Development Using Seaglider (Trademark).

摘要

This award was the second to APL-UW under ONR s Passive Autonomous Acoustic Monitoring (PAAM) program. It was intended to further develop the Seaglider PAAM system in various ways: redesigned hardware to improve computational and data storage efficiency, multiple hydrophones for enhanced detection and localization, and, in collaboration with colleagues at Oregon State University, improved detection and localization algorithms. A new electronics board was designed and built, with additional CPLDs and a bank of eight microSD cards for data storage. Software upgrades were written to enable long-duration (multi-month) missions. Survey missions became a high priority, particularly in remote U.S. Navy operating areas. Paths were established so that the Seaglider/PAAM system could be made available to other researchers.
