In early 2024, scientific investigation into unusual submarine seismic activity in the Indian Ocean, approximately 20 kilometres west of Wadjemup (Rottnest Island), led to the discovery of the tentatively named Perth Fissure; a deep-sea trench of currently unknown area and depth. This exhibition showcases the preliminary findings of the Perth Fissure Deep Sea Survey, a multidisciplinary team of marine scientists, geoscientists, oceanographers, occultists, theologists, and xenolinguists. The Perth Fissure Deep-Sea Survey is generously funded by the Dagon Foundation.
