In the newly founded Helmholtz Institute for Functional Marine Biodiversity (HIFMB) in Oldenburg, Germany, we have initiated a project to investigate how environmental acoustic features relate to habitat use and variations in behaviour of multiple marine mammal species. The project’s resources include basin-wide passive acoustic monitoring (PAM) data sets from the Southern Ocean spanning 11 years at 20 sites collected by AWI’s Ocean Acoustic Lab. Because these data were obtained in one of the most pristine ocean locations world-wide, this project offers a unique opportunity to analyze habitat acoustics in virtual absence of anthropogenic sound effects. By drawing from terrestrial research, we aim to adapt and further develop existing acoustic metrics to analyze passive acoustic data from the Southern Ocean to develop maps comprehensively describing the temporal, spectral and spatial characteristics of the underwater acoustic environment, to assess variations in acoustic assemblages’ composition, and finally, to develop a comprehensive “toolkit” to assess acoustic habitat quality.
