TIDES is a public data system containing the world's largest ocean trash dataset, all collected by volunteers. These citizen science data are collected during the annual International Coastal Cleanup and by users of Clean Swell, Ocean Conservancy's ocean trash data collection app. When exploring this system, you can view ocean trash data at a global scale or even zoom into your local beach. Looking to do your own analysis? Easily download reports for any country, state, region or location.
