To contribute, users are asked to open a browser window and listen to underwater recordings made with an underwater mic, differentiating between the high-pitched sounds of feeding shrimp and the lower-pitched sounds of fish. They are then asked to tap an on-screen button when they believe they hear fish. If enough people contribute, the data should help automate conservation efforts. According to Simpson, “there are too many recordings for one person to sit down and listen to, and that’s where you come in. We need your help, and the help of others like you, to form a listening collective. Your data will then be used to train computers to listen for fish sounds automatically.”
