There is no quiet way to churn water. Noise pollution caused by ships is increasing in the Arctic Ocean as sea ice melts, creating more open channels for vessels. This study provides a glimpse into the sources and balance of sounds in a portion of the Arctic Ocean soundscape surrounding the Norwegian archipelago of Svalbard. Characterization of the soundscape provides essential data as the region quickly transforms. This study also considers human perceptions of underwater ocean noise and its impacts in the region, and it reviews current ocean policy, suggesting mitigation strategies and ways forward. Before the rapid development of industry, prominent sounds in this underwater soundscape came from geological and biological sources. As vessel traffic increases, primary sound sources may be shifting from wind to ship noise. Sea ice extent has decreased in all months and in almost all regions of the Arctic, impacting Arctic marine mammals (AMMs) as their rapidly contracting habitat fills with unfamiliar anthropogenic noise. Noise in the ocean's underwater soundscape degrades acoustic habitat. This study helps fill a gap in knowledge that has limited our understanding of how much underwater noise the eleven AMMs are exposed to and its effects, especially in consideration of the unique hearing and communication capabilities of each species. AMMs spend much of their lives in deep darkness and have evolved to depend on sound as their principal sense. They rely on sensory cues to learn and thrive in their environments. Hydrophones were deployed at 44 locations between 13 °E and 19 °E and 69 °N and 79 °N in April 2023. Wind, waves, and ice (geophony) dominated the soundscape's acoustic signature in remote locations, while human-caused sounds (anthrophony) were significant near Arctic shipping routes, fishing areas, and in fjords. Marine mammal vocalizations were detected near the ice edge, at fjord mouths, and in fjords. Collecting and interpreting data that help explain the changing composition of the soundscape may offer insights to guide regulation of anthropogenic noise in the ocean's underwater soundscape, contributing to management and conservation efforts. This dissertation is available in open access at AURA (https://aura.antioch.edu/) andOhioLINK ETD Center (https://etd.ohiolink.edu/etd).
