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
