The Sailing the Sonic Sea Symposium proposes to lend an attentive ear to what underwater sounds can reveal in a time of rapid change. The increase of glaciers collapsing, and the incessant noise created by commercial ships are examples of factors that impact the sounds of the oceans. These sonic changes are not harmless for marine species. With the oceans warming up at an unprecedent level, sounds (and noises) travel faster underwater, the oceans are louder and disorienting for many species relying on echolocation to communicate and orient themselves. The acoustic explorations of the changing conditions of our oceans from an anthropological perspective can further contribute to new forms of knowledge about how humans relate and are aware of the impact of climate change on the underwater world
