All monitoring locations and hydrophone systems have unique features that affect the ability to monitor ambient noise levels accurately. As anthropogenic underwater noise effects on marine species becomes increasing important globally, it is imperative to understand how best to consistently measure, analyze, and account for factors contributing to the soundscape. The Enhancing Cetacean Habitat and Observation Program, led by the Vancouver Fraser Port Authority, seeks to mitigate shipping noise effects on at-risk whales, particularly endangered Southern Resident Killer Whales. Utilizing two years of data from three different, cabled inshore hydrophone stations in the Salish Sea, this high-level review aims to help understand and address key environmental and anthropogenic factors that contribute to ambient noise. Contributions from: the hydrophone system and ancillary equipment; rain, wind and tidal currents; factors affecting sound propagation; biological presence; and vessel traffic a.....
