Data Analysis Component of Comparative Passive Acoustic Monitoring (PAM) technology assessment

The Pathway Program - Technology Validation: Passive Acoustic Monitoring Device

This study focused on assessing the efficacy of five ‘off the shelf’ PAM technologies for monitoring in the high flow environment of the Minas Passage.  These comparisons were made difficult by the different ways these devices function (classifiers) and the challenges of generating detectable pseudo clicks in a high flow environment from a device with a low source level. From an acoustics perspective, this study revealed that the icListen and AMAR are functionally equivalent at detecting harbour porpoise at the FORCE site. Additional considerations (e.g., costs and logistical constraints) are important for identifying which ‘conventional’ PAM instrument to advance to subsequent testing phases of the Pathway Program.
