Collaboration with Timo Aho

The installation utilizes sensors and real-time data to dynamically respond to changing tides and storm surges, creating an immersive experience that visually represents the effects of rising sea levels caused by climate change. Customized for each location based on IPCC data and local elevation, the scenarios depicted range from realistic projections for 2100 to more speculative visions for 2300.

For the Spanish Arch, the scientists Gerard McCarthy, Zoe Roseby and Katherine Dooley from Trinitycollege Dublin & Maynooth University, have combined the storm surge from Storm Eleanor (1.2m) with an average sea level rise for the year 2150 under the IPCC’s AR6 SSP2-4.5 sea level rise scenario (1m) (IPCC, 2021a) to create a line height of 1.9m

– LED-Lights on at high tide or storm surge
– Light on at high tide or storm surge when dark (under 300 lux)
– Real time data feed from Marine Institute sensors
– Light sensor: on/off according the ambient LUX amount
– Powered by custom built Solar PV feeding excess power to the grid
– Located at the Spanish Arch, Galway, Ireland
