Narwhals Flee Canadian Arctic Amid Rising Ship Noise Pollution

Narwhal populations near Canada's Mittimatalik (Pond Inlet) have declined by 90% since the early 2000s, with researchers and local Inuit hunters identifying increased ship noise pollution—linked to a 2015 Baffinland mine port opening—as a key driver, as studies show narwhals avoid vessel noise, disrupting their feeding and migration. Collaborative acoustic monitoring efforts have spurred industry changes like reduced shipping speeds, which have shown early positive effects on narwhal numbers during recent hunts, highlighting the need for stricter Arctic noise regulations as shipping activity grows in the increasingly ice-free Northwest Passage.
