The Marine Debris Action Planner (MAP) is a service developed by SALT and GRID-Arendal to (1) optimise the use of public funds spent on marine debris mitigation, and (2) enable coastal clean-up crews to succeed in delivering a steady supply of recovered materials into a circular economy value chain. This tool is based on a scientifically derived predictive GIS model of beach litter deposition rates based on coastline characteristics. This poster presents how we are developing the GIS and remote sensing model to predict where marine litter is most likely to accumulate on the Norwegian coastline. Some of the variables included in this research include the morphology of the coast, coastal curvature, coastal substrate type, weather and fetch, and proximity to sources of marine and land based pollution.
