Abstract
This audio paper examines listening practices, technologies and cultures within the scientific study of marine ecosystems. It mixes recordings of whale song and ocean sounds with the voices of its co-authors, marine mammal ecologist Dr Denise Risch and artist researcher Dr Mark Peter Wright. Moving across three phases of argumentation and reflection, the paper questions how underwater knowledge emerges through tools such as hydrophones, spectrograms and Artificial Intelligence. It situates the ears, bodies and imaginations of researchers to ask what constitutes sonic data when listening to worlds beyond the human.
