transported to the Arctic from several remote and local sources by different transport pathways (Fig. 1):
• air transport driven by atmospheric circulation
• ocean transport
• riverine transport
• sea ice transport
• coastal erosion and ground water discharge
• biological transport driven by migrating animals
