Urban environments and manicured nature, with unseen native diversity, have resulted in forgotten evolutionary histories and a reduced understanding of ecosystem relations. In this context, especially the aquatic plant biosphere is the object of collective amnesia. Algaphon is a hybrid installation where algae bubbles that ring at Minnaert frequency near algal filaments are rendered audible through a hydrophone. Online visitors can leave a voice message that is translated into photosynthetically active radiation (PAR) variations in a remote aquarium. The algae bubble’s response to human speech is then recorded and emailed back to the visitor to engage in a reflective dialog with algal species. The installation refocuses attention on nonvascular physiological mechanisms and invites viewers to think about how environments exist in a heightened dynamic to adapt to human actions.


Algaphone is selected as a part of Ars Electronica Festival 2021 (Sep 8-12, 2021)
