Polar Sounds is a collaboration between Cities and Memory, the Helmholtz Institute for Functional Marine Biodiversity (HIFMB) and the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI). Out of all the senses, sound is the one that travels the furthest in the oceans. Because of this, acoustic methods are becoming a critical tool that scientists are using to better understand the Polar seas and the marine biodiversity within. When sight is impossible, acoustic data can give us invaluable information on breeding habits, migration patterns and the ways in which anthropogenic noise negatively affects marine environments. Thus, studying the soundscapes of the seas can tell us a lot about how our oceans are rapidly changing. Through this project, sound artists and musicians reimagine these sounds to help provide alternative and new perspectives to our scientific data. The sound clips chosen for the project were recorded from hydrophones located in the Arctic and Antarctic seas and consist of a mixture of biotic, geophonic and human-made sounds.
