Hydrology 2.0 Sound Walk is a thirty-minute original locative media work created for Pula, Croatia, commissioned for Media Mediterranea 27: H2O Interface. Drawing on over 300 hours of hydrophone recordings gathered from aquatic systems worldwide over the past decade, the work maps this global underwater archive onto a specific urban environment, grounding planetary-scale ecological data in local place. The work treats water as both subject and material, responding directly to the festival's theme of water as interface, and invites festival audiences into an embodied, participatory listening experience that connects everyday public space with hidden acoustic ecologies through original soundscape compositions along the streets of Pula.
The work was commissioned by the Croatian Metamedia Association and premiered as part of Media Mediterranea 27: H2O Interface (2025), curated by Darko Fritz within an international program examining water as interface across art, science and technology. Media Mediterranea, presented by the Metamedia Association, has run annually since 1999 as one of Croatia's leading international media arts festivals, hosting international artists alongside a free public program for local communities. H2O Interface examined the relationships between water and the diverse human and non-human entities that depend on it, asking how living beings and material worlds interface with water in its many forms.
