Improvements to Passive Acoustic Tracking Methods for Marine Mammal Monitoring
This project investigated and implement several methods to improve the accuracy, efficiency, and applicability of model based passive acoustic methods to track marine mammals. Methods were developed and tested that: 1) Invert for soundspeed profiles, hydrophone position and hydrophone timing offset...
