Wildlife disturbed by human noise in Antarctica

Wildlife disturbed by human noise in Antarctica
——————————
Human-generated noise is disrupting wildlife in Antarctica, Earth.com reported citing a new study by researchers from the University of the Republic of Uruguay and Pompeu Fabra University.

Recordings from Ardley Island, a protected sanctuary for seabirds and seals, revealed that the low-frequency hum of a single power generator over a mile away is clearly audible within the reserve. This constant noise overlaps with natural sounds, potentially interfering with critical animal communication.

Penguins and seals rely on vocalizations for mating, feeding, and alerting danger. The study warns that mechanical noise can cause animals to alter their calls, increase stress levels, and reduce foraging efficiency. Although direct behavioral changes were not documented, researchers emphasize that chronic noise exposure threatens breeding success over time.

Antarctica’s busy research stations use numerous engines, but terrestrial noise has received little attention compared to ship noise affecting marine life. The study suggests mitigation measures such as placing generators behind ridges, using acoustic baffles, and switching to quieter equipment. The authors call for incorporating noise limits into Antarctic protected area management to preserve the continent’s fragile soundscape and protect wildlife. The findings appear in Ecological Informatics.
