The goal of the SeaClear project is to develop autonomous underwater and surface vessels for mapping, classification and collection of marine waste. Hopefully in the future, robots will be cleaning our oceans continuously, but for now, periodic ocean clean-up actions performed by divers and manned vessels remain the only option. However, to test the efficiency of the autonomous vessels being developed through the project, a baseline must be used for comparison, making monitoring the efficiency of current ocean clean-up actions essential to the project.
