Tidal Resonance (work in progress)

Tidal resonance is a phenomenon which occurs only under select conditions, namely when three factors co-occur. First, when deep ocean waves crash against a long continental shelf and are forced up and into a semi-enclosed gulf or bay. Second, this rhythmic propulsion of waves along the bay must occur at the same or similar frequency as the Earth’s tides. And third, the time between consecutive high tides must be comparable to the time it takes a wave to reach from the mouth to the end of the bay (approximately 12.5hrs). The pairing of these interconnected geographic anomalies leads to large waves and a massive intertidal range.

This multi-channel installation is a sonificaiton work which uses predictive tidal data from Port of Bristol (Avonmouth), with permission from the UKHO.
