  • Urban environments and manicured nature, with no sight unseen of native organism diversity, have led to forgotten evolutionary histories and a reduced understanding of ecosystem relations. The aquatic plant biosphere especially bears a collective amnesia  from the humans of its evolutionary roles. It wouldn’t be erroneous to use ‘out of sight, out of mind’ in the context of the biosphere of aquatic plants. While the contributions of these early species have been tremendous to shaping higher plants, they haven’t received a lot of focus in their role from non-scientific communities.

    Our work refocuses the attention on algae species and reflects on the role of these species in climate change in specific coastal regions, through very specific micro-capabilities. We were first inspired by algae sounds recorded underwater in the bay and river waters at the East Coast (East River / Hudson River) and West Coast (San Francisco Piers, Sausalito, Point Reyes) areas in the US. These microalgae traditionally form and release oxygen near their macroalgal filaments. When this oxygen is released, the relaxation of the bubble to a spherical shape creates a sound source that ‘rings’ at the Minnaert frequency.
