Oscillating between positive and negative 16mm black-and-white film is a sensorial attunement to the layered mysteries of oceanic zones. Abstracted studies and sonic traces of communicating species dwelling in the intertidal and midnight zones of the Pacific Ocean. Biosonar clicks of whales and vocalizations of seals are interrupted by the sounds of tanker engines, radar pings from commercial ships and the growing chorus of ocean mining. In the depths, the mammal with the largest brain tries to communicate through the noise of our dominion. What does it mean to listen, to intrude and to belong? (J.M. Martínez)
