The Corallinales is composed of Coralline algae, which will continue to grow throughout the duration of the exhibition. These marine plants deposit hard skeletons as they grow, providing the foundation for coral reefs. Coralline algae are highly susceptible to the effects of climate change, and their absence would destroy the reef. To create this installation, Ritson gathered algae-encrusted garbage from shallow reefs off urban Honolulu’s coastline. This debris sits at the bottom of two saltwater aquariums designed to replicate the way climate change will affect the ocean’s water chemistry. Specific Coralline strains that can survive in this warm, acidic environment reproduce and grow on panels submerged in the tanks, creating living paintings in the process.
