Sunken Shoreline (2016) captures a 2014 performance of climate-related tweets from around the world in realtime (#climatechange, #tarsands, #environment, fracking, #sustainable, among others), the year before the United Nations Educational, Scientific, and Cultural Organization (UNESCO) formed a “Charter for Sound” to emphasize sound as a critical signifier in environmental health. Mapping characteristics of these tweets to sonic parameters, users from the around the world sound out a call for our climate. Here, an array of audio processing submerges these sonic voices under a technological deluge that suggests an Atlantian future should we choose to ignore the calls to action.
