The propagation of sound underwater is influenced by variations of the environment in range, depth and azimuth. Many sound propagation models ignore the azimuthal dependence and solve two-dimensional (2D) problem in range and depth. In this project, various mathematical techniques for applying azimuthal dependence into a full 3-D sound propagation model will be investigated. The […]

Several fish species produce species-specific sounds that can be identified in the wild using Passive Acoustic Monitoring (PAM) (i.e. dataloggers configured with underwater microphones). Our project will use existing and new PAM recordings to monitor the distribution of several fish species in the western Canadian Arctic, with particular focus on a keystone Arctic species, the […]
