Fate of floating plastic debris released along the coasts in a global ocean model

Marine plastic pollution is a global issue, from the shores to open ocean. Understanding pathway and fate of debris fundamental manage reduce pollution. Here, floating discharged along coasts studied by comparing two sources, one based on river discharges other mismanaged waste coastal populations, using Lagrangian numerical analysis in ocean circulation model. About 1/3 particles end up 2/3 beaches. The input scenario largely influences accumulation toward main subtropical convergence zones, with South Pacific North Atlantic being mostly fed population inputs. number beached that several areas. Beaching occurs mainly locally, although significant travel long distances, allowing for connectivity.
