The work is a collaboration across the time zones of Hobart, Tasmania and London, UK, in the era of COVID-19, between Jan Hogan and Andreas Philippopoulos-Mihalopoulos writing on Japanese paper with ink and water. ‘Tracing Submergence’ brings together the materialities of the geological and the human, working through tracing and erasure, layering ways of listening to the digital other, a writing dialogue where neither is leading but both follow the movements of water.
