Assessment of communication masking in Antarctic marine mammals by underwater sound from airguns


Marine mammals depend largely on their sense of hearing. Underwater noise can lead to acoustic masking of biologically important sounds. Marine airguns used for scientific studies of the seabed produce this type of sound. In this project, models were developed to assess the masking potential of airguns on blue whale, fin whale, killer whale and Weddell seal communication. The results of the models also show that seismic surveys conducted at lower latitudes (Australia) may also have masking potential in remote areas at higher latitudes (Antarctica). In the majority of the scenarios considered, however, a severe masking effect only manifests at distances of up to 200 km.
