Amphibious Architecture is a public artwork that creates a dynamic and captivating layer of light above the surface of the water that makes visible the invisible through real-time sensing of the environmental health New York’s urban rivers. Two networks of floating interactive tubes, installed at sites in the East River and the Bronx River, house a range of sensors below water and an array of lights above water. The sensors monitor water quality, presence of fish, and human interest in the river ecosystem. The lights respond to the sensors and create feedback loops between humans, fish, and their shared environment. An SMS interface allows citizens to text-message the fish, to receive real-time information about the river, and to contribute to a
display of collective interest in the environment.
