Debris Tracker is an open data citizen science movement, powered by Morgan Stanley. Join us in creating a bigger picture of the plastic pollution crisis by using the app to report litter wherever you find it, from our oceans to your backyard. Every day, dedicated educational, non-profit, and scientific organizations and passionate citizen scientists from all around the world use the Debris Tracker app to record GPS data on inland and marine debris. To date, Debris Tracker users have contributed 2 million items to our open-data platform, hosted at the University of Georgia and accessible to researchers and curious citizens everywhere. Together we can create a more comprehensive understanding of marine debris and plastic pollution by collecting and sharing data, generating scientific findings, informing policy, and inspiring upstream solutions. See our website for more information on how to get started or to download data: http://www.marinedebris.engr.uga.edu/. Debris Tracker is a joint effort of the NOAA Marine Debris Program and the Southeast Atlantic Marine Debris Initiative (SEA-MDI) out of the University of Georgia College of Engineering. Continued use of GPS in the background can dramatically decrease battery life.
