Randomized trial identifies environmental impacts on odontocete occurrence in European straits, suggesting implications for conservation management.

The study aims to investigate the acoustic occurrence of odontocetes across four European straits and identify environmental influences.
Performed static acoustic monitoring using C-PODs across the North Channel, Sound, Strait of Gibraltar, and Dardanelles Strait.
Utilized Generalised Additive Modelling to analyze acoustic presence in relation to tidal cycle, sea surface temperature, moon phase, and underwater noise.
Focused on monitoring the presence of dolphin species and harbour porpoises.
Harbour porpoises were predominantly detected in the Sound and North Channel; dolphin detections were higher in the Strait of Gibraltar and Dardanelles Strait.
Significant associations with sound pressure levels were identified for both species across all monitored locations.
Tidal cycle and sea surface temperature significantly influenced odontocete occurrence, excluding the Dardanelles Strait.

A 2026 study studied this question.
