Tidmarsh is a 600-acre property near Plymouth, Massachusetts. After over a century as a large operational cranberry farm, Tidmarsh is now being restored to natural wetland. Researchers in the Media Lab's Responsive Environments group are developing sensor networks that document ecological processes and allow people to experience the data at different spatial and temporal scales. Small, distributed, low-power sensor devices capture climate, soil, water, and other environmental data, while others stream audio from high in the trees and underwater. Visit any time from dawn till dusk and again after midnight; if you're lucky you might just catch an April storm, a flock of birds, or an army of frogs.

Many current projects in the group are making use of the Tidmarsh site and the data. The flagship project is a cross-reality sensor data browser constructed using the Unity game engine to experiment with presence and multimodal sensory experiences. We're looking for new ways to explore and experience data about the environment. Built on LIDAR-scanned terrain data, the virtual Tidmarsh experience integrates real-time data from the sensor networks with real-time audio streams and other media. The soundtrack is based on real-time sensor data—flashes and ukulele notes occur when new data comes from each sensor. The music is driven by the sensor readings: higher pitches indicate warmer temperatures, for example. You can visit Virtual Tidmarsh yourself on Mac, Windows, or Linux by grabbing the app from our downloads page.
