Composer Jana Winderen in conversation with Knut Korsbrekke from Havforskningsinstituttet and Geir Pedersen from Christian Michelsen Research Institute about what they have experienced from listening under water. Artist and composer Jana Winderen has spent her life listening under water, creating artworks that bring her into contact with the shifting and sometimes precarious lives of mammals, fish and other organisms that live in the world’s waters. Scientists at the Institute of Marine Research in Bergen have long used sound as a way to map water currents and fish movements, through techniques such as hydrophone recording and echograms, to better understand this world beneath the waves. Where then do these two practices meet? One, a sound-focused, creative practice, the other a data-driven scientific research project. We ask Jana Winderen and members of the marine biology community to discuss where their work converges, how important listening is to our understanding of the oceans, and what science and art can learn from each other.
