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 SeagliderPAAM system could be made available to other researchers.
