Mapping of seafloor litter at coastal sites

This report presents the results of a pilot project carried out by SALT and Green-Bay, commissioned by the Norwegian Environment Agency, to build knowledge and test non-invasive methods for mapping seafloor litter.

The project had two main components: first, identifying suitable survey areas based on their potential for litter accumulation; and second, conducting field surveys using a towed video camera system. The report describes the methods applied in both phases and presents the main findings, including visual maps of litter distribution, litter composition, and an evaluation of the field survey and data collection approach.
