Executive Summary
Rising ship and activity noise in Arctic waters is masking wildlife signals, changing behavior, and prompting calls for stricter monitoring and rules
- Ten years of underwater observations were analyzed in Iqaluktuuttiaq and Cambridge Bay, Nunavut from 2015 to 2024
- Noise sources included ships, snowmobiles, machinery, aircraft, and other human activity
- Summer open water brought more vessel noise and higher frequencies above 1 kilohertz
- Winter ice cover reduced sound transmission and shifted loud sounds below 1 kilohertz
- Smaller vessels without GPS transponders were a major source of noise and were not fully tracked by satellites
- Narwhals in Eclipse Sound went quiet, stopped feeding dives, and altered movement when ships were nearby
- Conservation groups say voluntary IMO guidance is not enough and want mandatory quieter ship measures
Quick Facts
- What: Arctic underwater noise is increasing and harming marine life
- Where: Nunavut waters including Cambridge Bay and Eclipse Sound
- Why: Melting sea ice is opening waters to more human activity
- Who: Researchers conservation groups and Indigenous hunters
- When: 2015 to 2024 with impacts rising in the 2020s
