Marine Debris Tracker is available in Google Play. After reading below, if you have further questions about how to track or other issues, see our FAQ. One you download the app and accept the Terms, you will be taken to the start page with the logo. Click Track Debris to begin. Next, simply click on the drop-down list to find the item you want to track. Be sure your GPS is showing valid coordinates and then click Add to Log. Next, you can either add more items (simply find them and click Add to Log) or you can View and Submit or Show Map (shows only your data collected at this point on a map). At the View and Submit page, you can click on items in your list, then choose to delete them (if you made a mistake) or submit them to the database. Note: Your data is not submitted until you complete the submit step – this allows you to track and log items anywhere – you don’t need to be connected to a network to log and all your items will be stored until you submit. The first time you use Marine Debris Tracker, you will need to choose a username and password. This will allow you to view and download your data from the website. While usernames show up on the homepage with town locations for the last 5 tracked items submitted, the exact GPS coordinates are not available associated with any username. The public data available for viewing and download on the website is anonymous, and you need your username and password to see and download your data as a separate file (coming soon). If you want to keep it private, keep your username and password private only to you. Once you have registered once, your username and password is all you need to submit all your tracked data each tracking session (and can be stored in the phone so you don’t have to enter it each time you submit).

We hope you find the app fun and useful and that you now notice (and pick up) marine debris when you see it.
